Summary: The effects of live feed diets containing Brachionus plicatilis (B) and Apocyclops panamensis (A) on the survival, growth, and fatty acid composition of pikeperch larvae were investigated in two experiments. Several diets with different combinations of the live feed organisms were provided to the larvae. The results showed that a higher proportion of B. plicatilis in the diet led to improved survival and specific growth rates, as well as increased levels of the polyunsaturated fatty acid linoleic acid (LA).

Summary: This study aimed to investigate the effects of final glucose and sperm concentrations, different activation solutions for sperm motility, and dilution of semen on the cryopreservation success of cultured pikeperch semen. Results showed that specific concentrations and dilution methods had significant impacts on sperm motility and successful cryopreservation. Future efforts should focus on controlling spontaneous motility to further improve cryopreservation techniques for pikeperch semen.

Summary: The aquaculture production of pikeperch faces challenges due to high mortality in early life cycle stages and insufficient understanding of nutritional requirements. The fate of fatty acids during development and the impacts of available feed were investigated. Deficiencies in essential fatty acids led to dysfunctions and mortalities in pikeperch. Improvements in feed composition are needed to enhance pikeperch rearing success.

Summary: Although nursing pike-perch larvae indoors increases fish mortality, it leads to improved growth later in life and lower feed conversion ratio. Therefore, indoor rearing can shorten the growth period and increase fish yields.

Summary: This research aimed to assess the reproductive potential of hatchery-reared (F1) pike-perch broodstock fed with a commercial diet low in long-chain polyunsaturated fatty acids (Lc-PUFA), compared to wild (F0) pike-perch broodstock fed with forage fish. The study analyzed reproductive parameters, egg composition, hormone levels, and immune response. The results showed lower pseudogonadosomatic index and embryo survival but satisfactory hatching rate and larval size in F1 broodstock. Additionally, a decrease in arachidonic acid percentage and increased immunoglobulin levels indicated potential depletion of key fatty acids and immune system activation in F1 fish.

Summary: This study suggests that polyculture in a Recirculating Aquaculture System (RAS) may have varying impacts on fish production, depending on the species involved. A comprehensive analysis of the consequences of polyculture on three fish species revealed that some species may be more affected than others in terms of survival, growth, and behavior. This highlights the importance of considering all species and adopting a multi-criterion assessment framework in evaluating RAS polyculture.

Summary: The study aimed to investigate the effects of single or multiple sperm collection methods on sperm quality in pikeperch. Results showed that multiple sperm collection with catheter did not significantly impact sperm volume and density, while multiple collection with syringe led to a drastic reduction in sperm density. Additionally, sperm volume, density, and osmolality were significantly affected by sampling method and post-injection time.

Summary: The study found that the size of female pikeperch, water temperature, and the potential energy invested in reproduction by females can influence the length of hatching larvae. Maternal effects also seemed to impact the timing of larval growth, with larger larvae at hatching growing less on yolk sac reserves. Additionally, female size had a positive effect on larval starvation resistance, but only under cold conditions.

Summary: The study showed that immersing pikeperch in a sodium chloride solution did not cause significant stress, but led to short-term biochemical and hematological changes. Exposure to high concentrations of NaCl resulted in significant alterations in biochemical and blood parameters, however, these changes were temporary and the fish showed significant recovery abilities.

Summary: This study aimed to assess whether heart rate variability (HRV) could predict the affected hemisphere in acute ischemic stroke (AIS). By comparing HRV between patients with right hemispheric (RH) and left hemispheric (LH) stroke, it was found that LH stroke patients had higher HRV complexity, possibly due to increased activity in the parasympathetic system, while RH stroke patients had lower HRV complexity, possibly due to increased activity in the sympathetic nervous system.

Summary: This study compares the radiation sensitivity and repair mechanism efficiency of human breast carcinoma cells and peripheral blood lymphocytes under different doses and radiation qualities. The findings suggest that breast cancer cells are more biologically sensitive to proton beams and have lower repair efficiency compared to lymphocytes. This supports the use of proton therapy for breast cancer patients.

Summary: In this study, the researchers compared the effectiveness of four activation solutions for ide sperm motility analysis. They found that adding a minimum concentration of bovine serum albumin (BSA) and casein significantly improved the computer-assisted sperm analysis (CASA) parameters of ide sperm. These low doses of proteins were also effective in preventing sperm adhesion to glass slides.

Summary: This study investigated the transfer of fatty acids from broodstock diets to eggs and the time needed for the eggs to equilibrate to the diet in Southern flounder. The findings indicate that different diet treatments significantly affect the fatty acid composition of eggs, and it takes 8-16 weeks for the eggs to adapt to changes in the adult diet. These results are important for improving broodstock diets and feeding protocols in stock-enhancement programs.
