Evidence for adaptive explanations of semelparity in animals

Biological Reviews, Volume 101, Issue 6, Page 2716-2734, December 2026.
ABSTRACT Semelparity, the reproductive strategy of reproducing once, is widespread but uncommon in animals. Classes of models to explain the evolution of semelparity are based either on age structure and mortality schedules – demographic models in which high post‐reproductive mortality risk favours high reproductive effort and semelparity results from ...

The effects of green tea extract additive feeds on the growth performance and survival rate of the giant freshwater prawn (Macrobrachium rosenbergii) [PDF]

Songklanakarin Journal of Science and Technology (SJST), 2005
This study was designed to examine the effects of green tea extract (GTE) additive feeds on the growth performance in the giant freshwater prawn. Two separate trials were determined by using two different stages of prawn for initial stocking, one was the

Innovative Field Applications of Probiotics, Prebiotics, and Medicinal Plant Products for Disease Control in Aquaculture

Journal of Fish Diseases, Volume 49, Issue 11, November 2026.
ABSTRACT Disease outbreaks and the associated reliance on antibiotics pose major constraints to the sustainability of modern aquaculture. As regulatory pressures increase and consumer demand shifts toward residue‐free production, diverse biological interventions are gaining prominence as viable alternatives to chemotherapeutics.

Molecular characterization of the giant freshwater prawn (Macrobrachium rosenbergii) beta-actin gene promoter [PDF]

PeerJ, 2018
Constitutive promoters are important tools for gene function studies and transgenesis. The Beta-actin (actb1) gene promoter has been isolated from many species but remains to be cloned from the giant freshwater prawn (Macrobrachium rosenbergii).

Single‐Cell Transcriptomics and Metabolomics Reveal Glutamate Dehydrogenase as a Central Regulator of Nitrogen Metabolic Remodeling During Alkalinity Adaptation in Crustaceans

Advanced Science, Volume 13, Issue 60, 28 October 2026.
Single‐cell transcriptomics reveals the cellular response of Macrobrachium hainanense to carbonate alkalinity stress. Alkalinity stress impairs branchial ammonia excretion, induces mitochondrial dysfunction, and drives cell‐type‐specific changes in gills and hemocytes.

Reducing Dependency on Live Feed in Tambaqui Larviculture: Growth Performance, Histology and Economic Implications of Early Inert Feeding

Aquaculture, Fish and Fisheries, Volume 6, Issue 5, October 2026.
ABSTRACT This study evaluated whether an inert commercial feed can replace Artemia nauplii during the initial feeding of tambaqui larvae in an intensive larviculture system. Larvae were assigned to three feeding protocols: exclusive Artemia (A), mixed feeding with Artemia and Vitellus (AV) and exclusive Vitellus (V).

Exploring the significance of Kenya's indigenous and emerging blue foods for sustainable aquaculture development. A review

Journal of the World Aquaculture Society, Volume 57, Issue 5, October 2026.
Abstract Kenya's aquaculture sector is at a pivotal stage, transitioning from a historical reliance on Nile tilapia and African catfish toward a more diversified production portfolio that integrates indigenous and emerging freshwater and marine species. This shift is increasingly recognized as essential to enhance climate resilience, food security, and
