Abstract:
... Brycon hilarii is a neotropical fish whose population in rivers is being threatened by overfishing, construction of hydroelectric dams, transposition of riverbeds, and pollution. Fundamental knowledge of the reproductive characteristics of this species is necessary to enable its breeding in captivity, for aquaculture as well as for biological conservation. The aim of this study was to investigate ...

Abstract:
... Reproduction in fish is influenced by several environmental factors. In many cases, failure in reproduction is common once fish are no longer in their natural habitat. Thus, the use of exogenous hormones has been crucial to control the reproductive cycle of many fish species under ex situ conditions. These hormonal stimulations became yet more important for those species facing extinction, as the ...

Abstract:
... Hormonal stimulation of spermiation is the most commonly used method for carp kept in captivity. Recent studies have suggested that hormonal stimulation of carp resulted in changes of the seminal plasma proteome. However information regarding proteome changes in spermatozoa upon hormonal stimulation is lacking. Here, we aimed to compare the sperm quality parameters and spermatozoa proteomes of hor ...

Abstract:
... Atlantic sturgeon (Acipenser oxyrinchus), also known as Baltic sturgeon, is considered extinct in German waters. Fish‐rearing for conservation purposes largely relies on classical hatchery technology focusing on traits like survival and growth in captivity but rarely focusing on subsequent life in the wild, lacking skills such as foraging or anti‐predation behavior. Predation is hence a major fact ...

Abstract:
... Aquaculture of Spinibarbus denticulatus (Oshima, 1926), a fish species indigenous to North Vietnam and Eastern China, is constrained by lack of fingerlings for stocking ponds and cages. As these fish do not naturally breed in captivity, carp pituitary extract (CPE), luteinizing hormone-releasing hormone analogue (LHRHa) with domperidone (DOM) and human chorionic gonadotropin (HCG) were administere ...
