Global Change Biology, Volume 32, Issue 3, March 2026.Rising temperatures can unbalance the number of males and females in species whose sex is influenced by the environment. In a decade‐long experiment with European sea bass, we found that heat during development produces more males, but the thermal history of parents—especially fathers—can unexpectedly push offspring sex ratios back in the opposite ...

Glycoproteins histochemistry of the gills of Odontesthes bonariensis (Teleostei, Atherinopsidae)
Journal of Fish Biology, 2010 The histochemistry of glycoproteins (GP) in the mucous cells of the gills of the silverside Odontesthes bonariensis was identified with: (1) oxidizable vicinal diols; (2) sialic acid and some of their chain variants, carbon 7 (7C), carbon 8 (8C) or carbon 9 (9C); (3) sialic acid residues without O‐acyl substitution and with O‐acyl substitution at 7C ...

Early Nutritional Programing: Unlocking the Potential of Fish for Sustainable Aquaculture
Aquaculture Nutrition, Volume 2026, Issue 1, 2026.Nutritional programing, which explores the link between early nutritional conditions and their long‐term effects on animals, is a developing field within fish biology. Suboptimal nutritional status during early life is strongly associated with a higher risk of metabolic consequences later in life, including permanent growth retardation, impaired neural
