“…The temperature during the controlled reproduction was kept constant at 12°C and the photoperiod comprised a photophase of 14 hr. Only females at maturation stage I were used for experiments to conform to the procedures for domesticated broodstock; it has been reported that the maturation stage of females upon injection may have a significant effect on the quality (Żarski, Kucharczyk, et al, 2012) and composition (Żarski, Krejszeff, et al, 2012; Żarski Palińska‐Żarska, Łuczyńska, & Krejszeff, 2017) of eggs in percids. After the ovulation was confirmed, the eggs were collected in the plastic sealable containers and were stored for no longer than 30 min before further use.…”

Pikeperch, Sander lucioperca, is a species of high interest to the aquaculture. The expansion of its production can only be achieved by furthering domestication level. However, the mechanisms driving the domestication process in finfishes are poorly understood. Transcriptome profiling of eggs was found to be a useful tool allowing understanding of the domestication process in teleosts. In this study, using next

“…Its flesh is appreciated and the Eurasian perch belongs among the most promising fish species to promote freshwater fish diversification [18–20]. Perch domestication is still under process and its reproduction has already been investigated allowing a good knowledge of its reproduction cycle [18, 20–27], egg quality [28, 29] and larval development [30]. However, only few studies investigated perch embryonic development [31–33].…”

BackgroundFish correspond to the most diversified phylum among vertebrates with a large variety of species. Even if general features are distinguishable during the embryogenesis, several differences in term of timing, organ implementation or step progression always occur between species. Moreover, the developmental timing of wild non-model fish often presents variability within a species. In that context, it is necessary to define a model of developmental table flexible enough to describe fish development by integrating this variability and allow intra- and inter-specific comparisons. The elaboration of a model passes by the definition of new stages that could be easily observable on individuals. The present study aims at proposing such a model and describing accurately the Eurasian perch (Perca fluviatilis) embryogenesis using microscopic techniques among which time lapse video and histological studies. The Eurasian perch belongs to the Percidae family that includes 235 species classified in 11 genera. It is a member of the Perca gender and inhabits the Northern part of Europe and Asia.ResultsAt 13 °C, P. fluviatilis development elapses for 15 days from the fertilization to the first oral feeding. The staging division first took into account the cellular status to define periods, then the acquisition of new abilities by the embryo to further define stages. It allowed distinguishing two main stages during the cell cleavage period depending on the synchronization of the cell divisions, two stages during the gastrulation period depending on the cell speed migration and five stages during the organogenesis according to the acquisition of key abilities as proposed in the saltatory theory. During each stage, organs implementation was carefully followed with a particular attention for the visual and digestive systems. In addition, our study shows that embryos hatch at various developmental stages while they all begin to feed at a fixed date, 15 days after the fertilization whatever the spawn and the hatching date. These data give arguments to propose the first oral feeding as the best definition of the embryonic-to-larval transition.ConclusionsThe present model of developmental table combines flexibility and accuracy allowing detailed description of non-model fish species and intra- and inter-specific comparisons.Electronic supplementary materialThe online version of this article (doi:10.1186/s13227-015-0033-3) contains supplementary material, which is available to authorized users.

“…Experimental fish were transported to the Centre of Aquaculture and Ecological Engineering in Olsztyn (20°27′43.203” E, 53°45′12.382″ N). Before the beginning of experiments, fish were caught and immediately anesthetized with MS-222 (Finquel, Argent Laboratories, Redmond, WA, USA) for Siberian sturgeon 125 mg dm −3 [ 19 ], for rainbow trout 150 mg dm −3 [ 20 ], and 150 mg dm −3 Eurasian perch [ 21 ]. For each experiment, we used 180 individuals per species.…”

Squalene is an antioxidant that plays an essential role in fat metabolism. The study aimed to assess the effect of squalene supplied in feed on the growth performance, health status, and fatty acid profiles of muscle and liver of Siberian sturgeon, rainbow trout, and Eurasian perch. The experimental feeds containing 0%, 0.5%, and 1.0% squalene were prepared for each fish species. Hematological and biochemical indices, liver histology, and fatty acid profiling of muscle and liver were analyzed. Squalene supplementation was safe for fish, and no negative influence on growth status was observed. However, changes in the values of hematological and biochemical indicators were found, including the level of triglycerides in the blood of rainbow trout, and cholesterol in the blood of Eurasian perch. The addition of squalene influences the nucleocytoplasmic index values in all fish offered feed containing 1% squalene. The retention of squalene in the liver and muscle of experimental Siberian sturgeon was observed in both 0.5% and 1.0% squalene levels of feed. The PUFA and docosahexaenoic acid increase was observed in all fish in groups with squalene addition. Dietary squalene increases the content of PUFAs in tissues of the examined species.
