Metabolic growth differences between Gymnocypris przewalskii and Gymnocypris eckloni: A quantitative proteomic perspective

Journal of the World Aquaculture Society, Volume 56, Issue 2, April 2025.
Abstract Metabolism plays a crucial role in the growth rate of species. Proteomics serves as a potent tool to explore these metabolic changes. Herein, we investigated the metabolic growth differences in Gymnocypris przewalskii (GP) and Gymnocypris ecklon (GE). After 9 months of culture, the growth rate of GP was slower than that of GE (p < 0.05), while

Occurrence of natural triploidy in Rhamdia quelen (Siluriformes, Heptapteridae)

Genetics and Molecular Research, 2010
Five specimens of Rhamdia quelen collected from the Lindóia Stream, PR, Brazil, were cytogenetically analyzed. The diploid chromosome number found was 58, including 30 metacentric, 16 submetacentric, 10 subtelocentric, and 2 acrocentric chromosomes. Supernumerary or B chromosomes, frequently observed in this fish group, were not detected.

Recent advancements in aquaponics with special emphasis on its sustainability

Journal of the World Aquaculture Society, Volume 56, Issue 1, February 2025.
Abstract An aquaponic system which is an integration of hydroponics with aquaculture is sustainable, ecologically friendly, and uses non‐renewable resources with very high efficacy. The increasing trend in aquaponics research demonstrates a growing recognition of its potential to address critical global issues such as food security, water conservation,
