Molecular Characterization and Expression Analysis of Cyp19a Gene of Schizothorax oconnori in Relation to Sex Differentiation

Aquaculture Research, Volume 2025, Issue 1, 2025.
Schizothorax oconnori has evolved various adaptations to the region’s extreme conditions, including low temperatures and high altitudes. This study showed that the full‐length open reading frame (ORF) of the SoCyp19a gene reveals a sequence encoding a 517 amino acid protein. SoCyp19a protein shares high sequence identity with other fish species’ Cyp19a

High Level of Dietary Sunflower Oil Affects Growth Performance, Serum Biochemical Index, Antioxidant Capacity, Lipid Metabolism, and Inflammation in Large Yellow Croaker, Larimichthys Crocea Juvenile

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%,

Global population size and conservation priority areas for the endangered Titicaca grebe

The Journal of Wildlife Management, Volume 88, Issue 8, November 2024.
The Titicaca grebe is an endangered endemic species found solely in Lake Titicaca, which has not had a population census in 20 years. We offer the first update of this species’ population since 2003, and show its population has increased, rather than suffered the decrease that had been assumed.

Ecología alimenticia del pejerrey (Odonthestes bonariensis)

Revista del Museo de La Plata, 2023
El estudio de la alimentación de los peces de agua dulce ha llamado la atención de muchos autores, especialmente norteamericanos, que desde Forbes, en la segunda mitad del siglo pasado, han llegado a dar un cuadro bástanle completo para muchas especies neárticas. El alimento como factor del ambiente (factor ecológico) es importante, y en el pejerrey, a

Addressing conflict between fishermen and the Titicaca Grebe (Rollandia microptera) through diet analysis

Ibis, Volume 166, Issue 4, Page 1395-1403, October 2024.
Human–wildlife conflict is often a driver of species declines, and understanding the material basis of this conflict is the first step in addressing it. The Titicaca Grebe Rollandia microptera is an endangered endemic species found solely in the Lake Titicaca watershed of Peru and Bolivia, and has experienced population declines due to fisheries ...

Modeling potential consequences of climate‐driven sex reversal on Southern and Summer Flounder population dynamics

Marine and Coastal Fisheries, Volume 16, Issue 2, April 2024.
Abstract Objective We investigate the interacting effects of fishery selectivity and sexual dimorphism by using the fisheries for Southern Flounder Paralichthys lethostigma and Summer Flounder P. dentatus as case studies. In both species, females are larger than males, and temperature‐sensitive sex determination can lead to an increased proportion of ...
