Zooplankton richness, abundance and biomass of two hypertrophic shallow lakes with different salinity [PDF]

, 2012
The zooplankton of lakes is controlled by biological and physico-chemical parameters. Among the former, predation by fish can determine the replacement of large-sized species by small-sized ones and among the latter, salinity exerts negative effects on ...

Artemia Enrichment Strategies: A Comprehensive Review of Nutritional Enhancements With Emphasis on Fatty Acid Profiles in Aquatic Species

Reviews in Aquaculture, Volume 17, Issue 4, September 2025.
ABSTRACT Artemia (brine shrimp) is a foundational live feed in global aquaculture, renowned for its adaptability, ease of production, and favorable nutritional profile. However, in its natural state, Artemia contains suboptimal levels of highly unsaturated fatty acids (HUFAs), particularly docosahexaenoic acid (DHA) and eicosapentaenoic acid (EPA ...

Problems with combining modelling and social science approaches to understand artisanal fisheries bycatch

Diversity and Distributions, Volume 31, Issue 3, March 2025.
Abstract Aim Artisanal fisheries account for 40% of the world's fisheries catch, yet its environmental impacts remain poorly understood. This is especially the case in developing countries. In this study, we sought to integrate Local Fisher's Knowledge with distribution modelling to estimate the annual bycatch of Titicaca Grebe (Rollandia microptera ...

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

Bile Pigments in the Bile of Freshwater Fish, Rainbow Trout, Tilapia, and Pejerrey

Agricultural and Biological Chemistry, 1988
Bile pigments in the bile of the rainbow trout, Salmo gairdneri, tilapia, Tilapia nilotica, and pejerrey, Odonthetes bonariensis, were analyzed by HPLC and TLC.Major bile pigments of rainbow trout and pejerrey were bilirubin glucuronides and ditauro-bilirubin, respectively.

Early morphological variation and induction of phenotypic plasticity in Patagonian pejerrey [PDF]

Neotropical Ichthyology, 2012
The aim of this work was to study two aspects of phenotypic plasticity in the Patagonian pejerrey Odontesthes hatcheri (Teleostei: Atherinopsidae) the dependence of the early morphology on developmental time and temperature, and the induction of morphological changes by controlled feeding in juveniles.

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%,

¿El pejerrey puede causar cambios estructurales en un ecosistema?

Biología Acuática, 2019
La laguna Del Estado se secó circunstancialmente a comienzos de la década de 1960. El aislamiento hidrológico superficial del ambiente impidió la recolonización masiva de peces.
