Background. Fish are the principal source of n-3 and n-6 fatty acids for humans. Traditionally, these fatty acids have been supplied in the form of captured marine and freshwater fishes. Recently, freshwater cultured species have been increasing their share in the fish volume on the market. Therefore it is crucial for fish farmers to rear fish under proper condition and with proper feeding in order to receive good quality fish flesh at harvest. The presently reported study was aimed at determining the effect of diet with the increased level of lipids or carbohydrates on selected blood indices, reduced glutathione content, lipid peroxidation products concentration in the liver, and body weight gains in carp fingerlings reared in post-cooling waters. Materials and Methods. The experiment was carried out in spring (2004) on 300 carp divided into two feeding groups. Group I was fed high-fat feed, whereas group II high-carbohydrate feed. After 7 weeks, fish blood and livers were collected for further analyses. Results. Significantly higher body weight gains were found in the fish fed high-fat feed as well as significant increase of haemoglobin (Hb) concentration in the blood of both feeding groups, which was accompanied by the increase of haematocrit (Ht) index. Furthermore, an increase in the concentration of lipid peroxidation products was observed as well as significantly lower content of reduced glutathione (GSH) in the livers of fish examined. Conclusion. The observed MDA values and reduced glutathione (GSH) concentration in the fish liver may indicate enhanced peroxidation processes in the organisms of the fish from both experimental groups, caused by their intensive feeding with extruded feeds. The peroxidation processes were more intensive in fish fed high-fat feeds.

The present study was conducted on two-year-old carp, reared in the production-scale conditions. The fish were kept for 62 days in cooling water and fed feeds differing in the fat content (35.9% of the energetic value of the diet) and carbohydrate content (35.6% of the energetic value of the diet). The experiment resulted in statistically significant differences in the levels of glucose, lipids, and blood lipoproteins as well as in the body composition of the fish in relation to the pre-experiment values and in relation to the other nutritional groups.

It was determined in the present study that a 14-day stay of carp in blue, yellow, and red aquaria caused significant increase of cortisol levels compared to its initial state and to that of fish kept in aquaria of a natural colour. This in turn caused a decrease in the levels of sodium and chloride ions and statistically significant decrease in potassium ion content.

The experiment was run on carp individuals in their second year of life. The fish were randomly divided into two groups fed two different isoprotein diets, one with increased fat level (Group I) and the other with increased carbohydrate level (Group II). Cortisol, total protein and protein fraction contents, AspAT and AlAT activities, and body composition and weight increments were monitored. Statistically significant differences between the two experimental groups were found in cortisol content, albumin level, blood AspAT and AlAT activities as well as in dry weight, total protein, and fat contents of the fish body.

The experiment, carried out in the aquarium room of the Faculty of Marine Fisheries and Food Technology, involved 72 carp juveniles. The fish were kept in 6 aquaria for 12 weeks without food. Levels of crude protein, AspAT and AlAT activities, levels of glucose, triacylglycerols, cholesterol and its fractions as well as body weight reduction and body composition were analysed. Starvation was found to significantly affect the crude protein level and AspAT activity as well as the blood levels of glucose, triacylglycerols, cholesterol and its fraction and the body chemical composition. The significant changes occurred both in relation to the initial status of the fish and between successive stages of the experiment.

Fisheries structure is associated closely with habitat conditions. Even small changes in hydrochemical conditions can affect the composition of ichthyofauna, and, therefore, catch structure, which is notable even after just a few years. In contrast, drastic changes in habitat conditions can affect ichthyofauna structure through the high mortality of economically valuable fish. The trophic status of Lake Miedwie waters has decreased in recent years, while catches of predators have increased. Cyprinid catches result from the high productivity of the lake in the 1980s and 1990s and the high tolerance these fish have for environmental conditions.

The interrelation between fishing bait color and size and the species and size of fish caught using these baits was investigated in the spring and fall of 2010 from the Skośnica Canal to Dąbie Lake in Międzyodrze. The fishing lures comprised two different colored twisters (motoroil and pearl) of three different sizes (3.5 cm, 6.5 cm, 9 cm). A total of 179 fish of three species - perch, pikeperch, and pike, were caught. The perch and pikeperch showed preferences for bait color, as more fish were caught with the motoriol twisters than with the pearl-colored bait. No such preferences were noted with regard to pike. Additionally, it was determined that bait size had a significant impact on the size of the fish caught.
