Die Brutanlage des AV Prüm im Wandel der Zeit Our "nursery" The hatchery Return From the Brunnenstube to the hatchery Load More .... after the renovation After the extensive renovation work in 2008, during which the dilapidated floor and ceiling were renewed, in the following years the complete water supply, water enrichment, and filtering and the entire electrical installation were brought up to date, the hatchery is equipped with additional breeding channels, holding tanks and one unique, experimental electrostatic hatcher ready for the future. Time travel to 2006 - functional but shaky. In the meantime getting old and the growing number of eggs no longer growing, it was time to change something. Extensive work was required to ensure that our water attendants were able to offer a better and safer workplace for the complex and time-consuming brood care. The wooden planks were dangerously slippery and sometimes fragile - light was only donated by a weak, outdated neon tube in the dark winter months. For the breeding season 2007/2008 this should be a thing of the past. After many hours of voluntary work and with the help of donations from the RWE, the "new" hatchery was handed over to the water body on time. Before the breeding ground of our "Eifeler brown trout" had moved to the hatchery in the early 90s, there was the Brunnenstube. The Brunnenstube is located about 2 km from today's hatchery. The spring water collected here used to supply drinking water. However, since the line dates from before World War I and therefore no longer meets today's drinking water production standards, it was made available to the association. So it happened that the first offspring were bred in this 1.2 m wide, 3 m deep and 2.4 m high shaft in 2 breeding channels. About 7 rungs of a rusty ladder were used to get into the shaft, to sort out dead eggs in the light of a flashlight and later to take care of the seedlings. The Brunnenstube is a bit "off the beaten path" so that it was actually not reasonable to do the brood service alone in winter, at a time when the cell phone was still a dream of the future. The logical consequence - the hatchery - which made life a lot easier at the time, is now a presentable hatchery. Unfortunately, we do not have any pictures from this period. The photos of the Brunnenstube shown here date from 2015. At that time there was a decline in the water supply in the hatchery, which was due to the leaking pipework in the Brunnenstube. This dates from the early 90s and can be seen in the pictures. Below again the plant in the brood house 2017 in direct comparison to the Brunnenstube - It clearly shows the long way we have taken since the beginning of the project. A path that we can rightly be proud of. Here the hatchery in 1994. It shows Erhard Nieder and Klaus Abels fishing off the seedlings. These were placed in the fountain room for the last time in 1993 and later (spring 94) transported to the incubator. It was then completely finished in 1995 with the completion of the plastering work. For the next 13 years, the system served the association well and paved the way for more than 2 million small brown trout to escape. Today, 14 years after the renovation, we are already over 4 million and there is still no end in sight.

The brook trout Salvelinus fontinalis Mitchill 1814 This colorful representative of the salmonids was imported to Europe from North America as early as 1884. It is therefore classified as a neozoa, alien animals that have entered a faunal area that was originally inaccessible to them through the involvement of humans. It is a very popular fish among anglers and is also valued as a food fish. However, natural reproduction is rare in Europe, so the species can only be preserved by stocking. Because even if it hardly reproduces naturally, the animals form sex products and the artificial reproduction largely corresponds to the methodology used with our brown trout. The incentive to produce these fish yourself is due to the fact that it was not possible to obtain animals in the colorful appearance so typical of the brook trout, as it is often portrayed. Why is that? The brook trout is usually used for edible fish production and not as stocking fish - which is a good thing. It simply has no place in open waters, since it hunts its prey in direct competition with the brown trout and occupies similar water structures, potentially displacing them as well. Further advantages compared to the brook trout are that brook trout hardly need shelter - as is unfortunately often the case with our straightened and therefore fast-flowing streams, as well as the better tolerance of acidic water - due to spruce monocultures. So these fish don't belong in open water and are intended as food fish or for angling - most of them end up straight from the farm directly onto your plate. It is only to be expected that fish farmers have looked for a way to increase their yield, a way that does not necessarily serve the preservation of the natural species, its appearance and it has been found. The solution to being able to produce larger quantities faster is the "Alsässer-Saibling" or "Salvelinus alpinus x fontinalis", a hybrid that was probably first grown in Alsace. In this crossing, Arctic char (alpinus) is used on the female side and brook trout (fontinalis) on the male side. In the case of hybridization, animals are usually optically closer to the mother species - here the arctic char - hence the weaker markings and marbling. It is also often claimed that "Alsatians" are sterile and incapable of reproduction - that is simply wrong. Hybrids are not necessarily sterile, but natural reproduction is as unlikely as that of the parent animals. Finding parents with the desired appearance, from a reputable source, turned out to be as difficult as it was tedious. The breeding stock was built up from young fish so that they could get used to the conditions in the breeding facility. We obtained animals from private breeders and even transported them from Bavaria to the Eifel. It should take 4 years until the first eggs could be stripped. In the spring of 2021, the first brook trout eggs arrived in the hatchery. These were picked up from a breeder friend of ours when they were in the eye point stage and we were able to gain initial experience in rearing the larvae up to the seedling. At this point let's go into a little more detail. Breeding the local brook trout naturally has absolute priority - brook trout spawn earlier, however, so we only lay small numbers of eggs, because there must always be enough space for the farios. Therefore, the eggs were placed in the incubator, which has a high capacity and is just as well suited for the rather small char eggs. An incubator offers various advantages over incubation in channels. The space requirement is very small with, in this case, 0.8 m² with a minimum water requirement of 2L/s and a capacity of up to 120,000 eggs. Another advantage is the possibility of separating the scrims according to trunks, each slot can be divided into up to 8 compartments. So can eggs in the eye point or too. Larval fish can be returned to their original waters. The average quantity of eggs in a brook trout rogner is 2,000 - 3,000 per kg of body weight. The eggs of our 4-year-old animals are approx. 3mm in diameter, they can be up to 5mm, so they are more than half smaller than those of the brown trout. So here on the right in the picture the fertilized eggs in the ocular stage. At this stage, the eggs are largely insensitive to transport. You have to know that we handle the eggs won as little as possible during incubation. A transport is only unfertilized (roe and milk separated), here the fertilization takes place immediately after arrival in the incubator, shortly after the fertilization in a small time window and just after reaching the eye point. This is quite easy to recognize - the eyes of the larva are now so far developed that they can be seen through the membrane of the egg. For transport, the laid eggs are removed from the water, divided into compartments in an insulating container, which, similar to the incubator, are divided into shelves and then stacked. It may sound wrong at first that the eggs are transported dry, but that is exactly what prevents the eggs from moving too much, they are "fixed" so to speak, because they are not insensitive to shocks and vibrations, which inevitably take place in the sloshing water. The bottom floor is left free and the top one is filled with ice. This defrosts during transport, and the water then drips through the individual floors, thus ensuring sufficient moisture and cooling before it collects again on the lowest level. Arriving at the incubator, unfertilized eggs are then selected before they are placed in a slot in the incubator. This would have been possible in advance, but it would have been much more convenient to do it in the incubator. Since Salmonids usually multiply during the cold season, transport in this way does not pose a problem in terms of temperature. Depending on what reading you take, brook trout are given with 450 - 470 daily degrees. So let's assume an average of 460 TG at an average water temperature of 6°C, which results in a hatch around the 76th day. Our clutches had at 35-.40. Day reached the eye point, leaving almost 4 weeks time for a transport or 168 day degrees. You should always take this into account beforehand, because the temperature increases during the procedure and, depending on the duration, hatching can then possibly begin. Afterwards, everyone carefully returns to the water. Here now first in a larger underflow box of a long-flow trough, everything unfertilized is now read out (no eye point recognizable = rejects). Then it goes over the counting plate to determine the exact amount, already in the incubator. From here the daily care begins, as if you had put them on yourself, until hatching. Since brook trout, at least in Europe, are very likely to come from farms, there are usually no problems to be expected in further rearing, which means above all the conversion to exogenous food. Always a critical point in rearing that cannot be missed, but with wild fish this process can often be fraught with problems. Here are the hatched brook trout in the larval stage. They can best be described as the size of a pin - really very small and filigree. It is all the more astonishing when you imagine that such a tiny thing will become what you will see below. When the first brown trout were released into the wild in April, the char were able to move into a channel that had become free - still quite small but already moving much further in the direction of the fish. From here on, however, the little ones develop quite quickly, with increasing feed size the more steadily and faster. The three pictures above show the development quite well. On the right you can already see the characteristic juvenile stripes that are already forming on the flanks, the development of the fins and their reddening as well as the white fin rays. We would have liked to have followed and recorded the development of the small brook trout for longer, but unfortunately this was not possible. On July 14, 2021, the hatchery in Willwerath was damaged by the flood and the water supply was destroyed. Luckily the water in the facility was "only" knee high and all the remaining broodlings in the facility could still be evacuated as the water did not reach the pools. Parallel to incubation, we have been looking for year-old animals in order to enable earlier entry into breeding. By selecting animals from other sources and the bred ones, the aim is to create a gene pool that is as broad as possible. As mentioned at the beginning, we had found a company that breeds high-quality fish in Bavaria and was willing to provide us with a sufficient quantity. For the transport of more than 600km we left in the middle of the night to arrive at the destination in the early morning. The trip took place at the end of March, so no temperature problems were to be expected. The transport trailer has the necessary oxygen system with EPDM air vents and an insulating container that protects the 600 liters of water from heating up during the journey. Arriving at the breeding facility, our fish were already waiting in the tanks to be picked up. They were caught from the pond the day before, which significantly reduces the stress of transport, as the fish return to the water quite quickly when transferred to the transport container. After adjusting the oxygen system the fish could be loaded and we made our way back to the Eifel. However, this took longer than the way there - every 45 minutes we took a break to check the oxygen saturation with the oximeter and make adjustments if necessary. The saturation was kept at an average of 95% over the entire route. Back home, all the char survived the transport well and we could start adjusting. The water only warmed up by 1.5°C during the trip. A third of the water has now been drained from the tank and gradually filled up with water from the pond. In this way, the animals could get used to the water values in a gentle manner and then be moved. What was left to do now was - wait. The fish had an average size of 15 cm and should have reached the 30 cm mark by the age of three. For this purpose, the feeding began with feed that has an increased carotene content. From 2mm up to 6mm grain. Char have a smaller mouth gap - therefore smaller grain sizes should always be chosen than with brown trout. After the long wait, we were able to win the first brook trout eggs from our own fish at the end of 2022 and lay them in the hatchery. The animals have developed excellently in recent years, as can be seen in the following pictures.

Eel-Care During its complex life cycle, the eel is exposed to many adverse influences such as pollution, overfishing of the young eel stocks (glass eels are a delicacy!), Climate change, diseases, parasites and predators. The eel has been on the "Red List" of endangered species since 1987, and today its stocks are considered "highly endangered" mainly because the glacial eel production on the coasts accounted for two to five percent of the amount at the beginning of the 1960s decreased n is.

Wie züchtet man originale Eifeler Bachforellen salmo trutta fario "Eifel brown trout" Back The stripping of farmed fish Every year in the first weeks of December, project work begins for us when our spawning trout are stripped. Each of these hand-picked trout comes from wild catches of regional streams or from the breeding program itself. A main task is the regular "refreshing" of the spawning fish strain in order to incorporate a maximum of genetic diversity into the breeding program. For this purpose, the fishing club Prüm 1967 eV has a fixed spawn fish in the breeding facility "In der Litzer". Here the trout experience year-round care and care and can be stripped off with minimal stress. The seed (milk) of the male trout (Milchner) are then added to the eggs, and here too, as with spawning, several trout are streaked. Since there are usually more males than females available, the mixture is mixed in a ratio of 2 - 4, which benefits the genetic diversity due to the different mating. Water is added to the mixture for fertilization and carefully stirred with a goose feather. When they arrive at the hatchery, the eggs are rinsed out in clear water and carefully placed in the undercurrent boxes with a counting plate. From now on, these are checked daily and dead eggs are read out. Until the eye point stage is reached, the eggs cannot be transported and unnecessary movement is avoided. We expect about 420 daily degrees for our trout. This means that at a water temperature of 6 ° C, the larvae hatch after about 70 days The female trout (Rogner) are spread the eggs into a fine sieve with gentle pressure on the belly. The eggs are in ovarian fluid here, contact with water is largely prevented to prevent the egg membrane from closing. If you have enough eggs, put them in a smooth bowl. Left trout larvae just before hatching. You can clearly see the eyes and the torso through the eggshell, the orange color comes from the yolk sac, from which the larvae feed in the first few weeks before being fed. Larvae hatching and hatching below. Even if a continuous supply of fresh, oxygen-rich water is important throughout the breeding - from here on it is essential. Even brief disruptions can result in significant losses. In late April to early May, the time has come. The trout have outgrown the hatchery and need more space to thrive. A large part is brought to the "In der Litzer" pond for further breeding. Another part is released into the upper reaches in streams leased by the association. These are not fished, but only nurtured for spawning fish at large intervals. Trout become sexually mature at the age of 2-3. First spawners are not used for breeding purposes, at 4-5 years high quality roe / milk can be obtained and the cycle closes.

Beginn und Fortlauf des Nachzuchtprogrammes für die "Eifeler Bachforelle" aus Wildstämmen The beginning Conservation on behalf of the State of Rhineland-Pfalz Return Artificial reproduction of the "Eifeler brown trout" The fishing association Prüm 1967 eV has been actively protecting species in the form of the offspring of the "Eifel brook trout" since 1991. The University of Mainz (Prof. Dr. Alfred Seitz) carried out the first genetic studies on the importance of the regional brown trout population. When creating a population genetic profile of the "Eifeler brown trout" by Prof. Dr. Arndt Schreiber and Dr. Michael Riffel from Heidelberg University, it turned out that the "Eifel brook trout" - if not different from that of the Rhine catchment area - formed the most homogeneous group of all trout in the Rhine catchment area. In the years that followed, the Prüm Fishing Association 1967 eV stripped many thousands of trout eggs from as many varieties of brown trout as possible from wild stocks and released the trout seedlings it yielded into several previously damaged Eifel streams to preserve the "Eifel brown trout" at a young age. For this purpose, a specially built hatchery is operated, which is fed with 6 ° C cold, surface-independent water. Regular surveys of the populations of the occupied streams have shown that these measures, which are very time-consuming and labor-intensive for the fishing club Prüm 1967 eV, are crowned with success, since the wild brown trout are very true to location and reproduce particularly well. In this way, a self-reproducing stock could be established in many small streams. This is mainly due to the fact that only regional animals are used for breeding - autochthonous stocking - which means that the seedlings are already optimally adapted to their "new" environment through their genetic heritage. The biggest hurdle that stood in the way of breeding success were the scattered, partly unsafe ponds that were leased by the association. At this point, a cooperation agreement was concluded with the state of Rhineland-Palatinate. This included the work in the species conservation project "Eifeler brown trout and river pearl mussel" and as a result the construction of the later pond system "In der Litzer". This contract has existed for more than 25 years and has now led the association to international activity. In addition to the alliance partners in Rhineland-Palatinate and North Rhine-Westphalia, the EU life project river pearl mussel, in particular the "Hellef fir d'Natur" in Heinerscheid, also benefit from the work of the association.
