Olfactory Receptors in Acipenseridae Fish Larvae

1992
Basic aspects of the development of the olfactory system of Acipenseridae occurs during the period between the embryo’s hatching and its period of independent feeding. It was found that actively feeding Acipenseridae larvae have the same types of olfactory receptor cells as observed in adults (Pyatkina, 1976).

Jesetre (Acipenseridae) - relikti prapovijesne ihtiofaune

2000
U radu se prikazuju sistematika, biologija, areal rasprostranjenosti i mjere zaštita vrste riba iz porodice Acipenseridae. Posebno se iznose problemi i mogućnosti uzgoja jesetri u češkoj akvakulturi utvrđeno je da najveći problemi nastaju u početnoj fazi uzgoja mlađa, nakon prelaska ličinki na egzogenu prehranu, te, poslije, kad jednogodišnji mlađ ...
