Effects of Attractants on the Growth Performance, Antioxidant Capacity, Immunity, and Histology of Largemouth Bass Larvae (<i>Micropterus salmoides</i>). [PDF]

Aquac Nutr
This study evaluated the effect of four attractants on the growth performance, antioxidant capacity, immunity, and histology of largemouth bass larvae (Micropterus salmoides). A total of 75,000 larvae (~1.25 mg) were randomly divided into 15 tanks (five groups with three replicates), with 5000 larvae per tank. The experimental diets were isonitrogenous

Restoration and ecology of sterlets in the Austrian Danube – The way from LIFE-Sterlet to LIFE-Boat-4-Sturgeon

, 2022
Sturgeons are an essential faunal element of the Danube and provided a link between the Alpine Danube basin and the Black Sea through their migration in the past. Today, two out of six Danube sturgeons are already regionally extinct, and the remaining species are threatened with extinction due to poaching, bycatch, migration barriers and habitat loss ...
