The effects of shaded pond on growth performance of Russian sturgeon (Acipenser gueldenstaedtii)

, 2011
The aim of this study was to identify the effects of reduced daylight over shaded ponds on growth during adult rearing of Russian sturgeon (Acipenser gueldenstaedtii). Growth performance was determined as weight gain, condition factor, specific growth rate, and feed conversion ratio using 7+years old sturgeons.

Analysis of the effect of the sorbent probiotic drug “Florin Forte” on the cellular immunity of the Russian-Lena sturgeon [PDF]

E3S Web of Conferences
The paper analyzes the effect of the sorbent probiotic drug “Florin Forte” on the cellular immunity of the Russian-Lena sturgeon. The proposed dosages of the drug in compound feeds (4 g/kg, 6 g/kg, 8 g/kg) allowed us to evaluate the effect of the drug on

Genomic Prediction for Growth‐Related Traits in Golden Pompano (Trachinotus ovatus)

Evolutionary Applications, Volume 18, Issue 8, August 2025.
ABSTRACT Golden pompano (Trachinotus ovatus) is a rapidly growing marine aquaculture species along the southeast coast of China due to its favorable biological traits. However, the relatively short domestication history of marine species compared to terrestrial livestock and crops indicates untapped genetic potential.

Application of Machine Learning for Predicting the Abundance of Russian Sturgeon in the Sea of Azov Based on Historical Annual Ecosystem Dataset

Fishes
A new approach was applied for forecasting purposes of Russian sturgeon abundance in the Sea of Azov. Different types of supervised machine learning models were tested based on long-term data of Russian sturgeon abundance and ecosystem parameters of the ...

River Network Connectivity Reductions Dominate Declines in the Richness of Plateau Fish Species Under Climate Change in the Upper Yangtze River Basin

Water Resources Research, Volume 61, Issue 6, June 2025.
Abstract Anthropogenic climate change and disrupted river network connectivity are major factors affecting freshwater fish richness. However, the distribution patterns of this parameter under the combined influence of climate change and reduced river connectivity resulting from hydroelectric development remain unclear.

Growth modeling of the European grayling (Thymallus thymallus L.) in a large alpine river based on age‐at‐length, mark‐recapture, and length‐frequency data

Journal of Fish Biology, Volume 106, Issue 6, Page 1714-1723, June 2025.
Abstract Animal growth is a fundamental component of population dynamics, which is closely tied to mortality, fecundity, and maturation. As a result, estimating growth often serves as the basis of population assessments. In fish, analysing growth typically involves fitting a growth model to age‐at‐length data derived from counting growth rings in ...
