The Siamese fighting fish (Betta splendens) has great importance as an ornamental aquarium fish as well as laboratory model species. Due to its rapid development, a cooling-embryo protocol could provide some advantages in ...

The buoyancy of eggs and embryos is associated with successful development in pelagic fish. Buoyancy is the result of oocyte hydration, which depends on the osmotic force exerted by free amino acids (FAA) generated by yolk ...

The objective of this study was to assess the viability of Steindachneridion parahybae embryos after chilling using different cryoprotectant solutions, stages of embryonic development, chilling curves, and storage periods ...

The reproductive biology of the guitarfish Rhinobatos percellens was studied from 751 specimens caught by bottom pair trawlers off the coast of São Paulo, Brazil, between c. 24° 00′ S; 45° 15′ W and c. 25° 10′ S; 47° 52′ ...

This study investigated and analysed survival, growth and macro-and microscopic damage during the development of zebrafish embryos up to the adult stage after undergoing cooling. The embryos at 50% epiboly stage were ...

This review discusses the new biotechnological tools that are arising and promising for conservation and enhancement of fish production, mainly regarding the endangered and the most economically important species. Two main ...

Fish embryo toxicity (FET) test using zebrafish (Danio rerio) has been established as an alternative assay to animal experimentation. The FET assay enables the assessment of multiple morphological endpoints during the ...
