The present study evaluated the performance of two commercial diets: AgloNorse (AN) and BioKyowa (BK), and two experimental, formulated diets based on casein (C) or casein plus casein hydrolysates (CH) in rearing of pike-perch larvae (Sander lucioperca L.). All fish were 5 day old and control group was fed live Artemia nauplii. Fish were sampled periodically for histological comparison of morphological changes in the digestive tracts. Survival of fish fed Artemia nauplii, BK and AN was similar: 54.4%, 50.8% and 52.4%, respectively, while the fish fed formulated diets C and CH showed considerably lower survival: 28.4% and 21.6% respectively. After 5 weeks of rearing, the average body mass of fish ranged from 212±32 mg in Artemia fed group to 53.8±6.8 mg in C diet fed group. A considerable vacuolization of supranuclear zone in enterocytes of posterior intestine was observed in the larvae fed commercial diets. No anomalies in liver development were found. Hepatocytes of fish fed BK diet showed larger glycogen storage areas, compared with those occupied by lipids. The highest zymogen accumulation of pancreatic cytoplasm was observed in fish fed Artemia. In fish fed C and CH diets, anomalies in digestive system development were indicated by lower and less numerous intestinal folds, smaller hepatocytes, retarded development of gastric glands, and in CH group – also local fatty degeneration of liver.

- Effect of weaning age and diet on pikeperch larviculture (2007, background): “However, a recent paper (Ostaszewska et al., 2005) demonstrated that pikeperch larvae can be fed from day 5 post-hatching with high quality commercial dry diet as unique food source without significant reduction of survival and growth rates when compared with controls fed Artemia nauplii.”
- Histological methods in the assessment of different feed effects on liver and intestine of fish (2011, unknown): “Similar method was used by Ostaszewska et al. (2005), in the study of the effects of casein replacement in feed by soy on the rainbow trout and pacu (Piaractus mesopotamicus).”
