General and Comparative Endocrinology, 2015 The endocrine mechanisms that regulate spermatogenesis and their interaction with environmental cues have been poorly studied compared with oogenesis in fish. The aim of this work was to study the spermatogenesis in pejerrey under the influence of photoperiod and water temperature fluctuation in the wild, evaluating the transcript levels of brain Gnrh ...

Diversity and Distributions, Volume 31, Issue 3, March 2025.Abstract Aim Artisanal fisheries account for 40% of the world's fisheries catch, yet its environmental impacts remain poorly understood. This is especially the case in developing countries. In this study, we sought to integrate Local Fisher's Knowledge with distribution modelling to estimate the annual bycatch of Titicaca Grebe (Rollandia microptera ...

Presence of 11-ketotestosterone in pre-differentiated male gonads of Odontesthes bonariensis
Fish Physiology and Biochemistry, 2012 The involvement of androgens during sex differentiation period was investigated in the pejerrey Odontesthes bonariensis, by classic biochemical studies and gonadal histology. We studied in particular whether the enzyme activities involved in 11-oxygenated androgen production were active in a gonadal/peritoneum complex (GPC) of very small larvae exposed

Aquaculture Research, Volume 2025, Issue 1, 2025.Milt cryopreservation facilitates native fish’s constant production of commercial interest. However, it can damage spermatozoa (sptz) due to the osmotic stress of diluents and low temperatures. This study compares spermatic quality in fresh (SF) and cryopreserved (CS) milt in B. amazonicus for 24 h, 1 month, and 3 months.

Aquaculture Research, Volume 2025, Issue 1, 2025.This study aimed to evaluate the effects of fish oil (FO) replacement by sunflower oil (SFO) on growth performance, serum biochemical indicators, antioxidant ability, lipid metabolism, and inflammation in juvenile large yellow croakers, Larimichthys crocea (LYC). Five formulated diets that varied in the replacement level of FO by SFO (0%, 25%, 50%, 75%,
