Quantitative Genetic Variation and Response for Harvest Body Weight in a Selection Program for Red Tilapia (Oreochromis spp.)

Aquaculture, Fish and Fisheries, Volume 6, Issue 1, February 2026.
ABSTRACT Genetic variation is indispensable for both natural and artificial selection, as well as evolution, adaptation, and the long‐term success of selective breeding programs. This study attempted to scrutinise genetic variations and responses within the breeding population of red tilapia across eight generations of selection (2016–2023).

Influence of Tank Coloration in Modulating Physiological Growth, Survival and Skin Pigmentation Expression in Nursery‐Reared Channa striata

Aquaculture, Fish and Fisheries, Volume 6, Issue 1, February 2026.
ABSTRACT Tank colour is a crucial environmental factor that influences growth performance; however, its effect on Channa striata fry under laboratory environments is not widely recognized. This study investigated the influence of tank coloration on growth, survival, cannibalism, and pigmentation of C. striata larvae under nursery rearing conditions.

Easy or difficult? Investigating perceived ease of changing eating and physical activity behaviors

Applied Psychology: Health and Well-Being, Volume 18, Issue 1, February 2026.
Abstract Many people aim to eat healthier or become more physically active, yet often fail. Identifying aspects of behavior that are easier to change is crucial for effective interventions. Two preregistered online studies assessed participants' perceived ease of changing eating and physical activity (PA) behavior and explored potential moderators ...

Evaluation of a novel anti‐mycotoxin agent specific for aquatic species in mitigating aflatoxin B1‐induced changes in Nile tilapia: A comprehensive study

Journal of the World Aquaculture Society, Volume 57, Issue 1, February 2026.
Abstract Aflatoxin B1 (AFB1) contamination of aquaculture feed poses serious health risks to fish and consumers. In this study, the efficacy of a novel anti‐mycotoxin agent specific for aquatic species (AM‐AQ) containing bentonite, sepiolite, and orange peel meal (Citrus Sinensis) in alleviating AFB1 toxicity in Nile tilapia (Oreochromis niloticus) was

Calcium signaling in crops

New Phytologist, Volume 249, Issue 4, Page 1644-1658, February 2026.
Summary Calcium (Ca2+) signaling is integral to nearly all aspects of plant biology, including development and responses to biotic and abiotic stresses. It operates through two main layers: the generation of Ca2+ signals and their decoding by Ca2+‐binding proteins, which act early in diverse signaling pathways. The system exhibits remarkable robustness

Diversification of Aquaculture Production in Relation to Global Change: The Case of the Domestication of Indigenous Euryhaline Catfish Species (Siluriformes) in the Mekong River Delta, Viet Nam

Reviews in Aquaculture, Volume 18, Issue 1, January 2026.
ABSTRACT The Mekong River Delta, the heart of Vietnam's aquaculture industry, is facing many challenges due to climate change, particularly salinity intrusion. In this context, this review aimed to assess the potential of indigenous euryhaline catfish species to diversify fish farming, strengthen food security, and build resilience in the region. Among
