Beyond Hard Parts: Metabarcoding Advances Dietary Resolution in Threatened Amazonian Elasmobranchs

Aquatic Conservation: Marine and Freshwater Ecosystems, Volume 36, Issue 5, May 2026.
ABSTRACT Elasmobranchs are highly vulnerable and are considered one of the most threatened vertebrates worldwide. Insights into diet can improve conservation measures. The bias of traditional morphological methods towards taxa with distinctive hard parts makes metabarcoding analysis a complementary tool to assess diet composition. Here, we analysed the

Investigating Low‐Temperature Stress Responses in Crustacea Aquatic Species Through Comparative Transcriptomics

Evolutionary Applications, Volume 19, Issue 5, May 2026.
ABSTRACT Crustaceans, such as shrimp and crabs, are pivotal to global aquaculture, yet their productivity is severely impacted by low‐temperature stress. This study employs comparative transcriptomic and genomic analyses to elucidate the molecular mechanisms underlying crustacean responses to cold stress across five economically significant species ...

Molecular and Endocrine Regulation of Ovarian Maturation in the Black Tiger Prawn (Penaeus monodon) and Associated Challenges in Its Aquaculture

Reviews in Aquaculture, Volume 18, Issue 2, March 2026.
ABSTRACT Over the past four decades, substantial research has investigated the regulation of ovarian maturation and spawning in the black tiger prawn (Penaeus monodon). In this species, female reproduction is strongly suppressed by gonad‐inhibiting hormone (GIH) released from the eyestalk, making eyestalk ablation (ESA) the most widely adopted spawning‐

Is There Extraovarian Synthesis of Vitellogenin in Penaeid Shrimp?

The Biological Bulletin, 1992
Extraovarian synthesis of vitellogenin (Vg), has been reported for several crustaceans, mainly in the subepidermal adipose tissue (SAT) or the hepatopancreas (HEP). The precise site(s) of Vg synthesis in penaeid shrimp is hitherto unknown and was investigated in a large local species Penaeus semisulcatus de Haan. Protein synthesis was determined in SAT

Heat Shock Proteins in Aquatic Larvae: Nutritional and Live Feed Modulation of Chaperone‐Mediated Stress Physiology in Fish and Shellfish

Reviews in Aquaculture, Volume 18, Issue 2, March 2026.
ABSTRACT Heat shock proteins (HSPs) are highly conserved molecular chaperones that maintain proteostasis under environmental and physiological stress. In aquaculture research, HSP responses have been studied primarily in relation to temperature, salinity, pollutants, and pathogens in juvenile and adult stages, whereas the nutritional regulation of HSP ...

Molecular cloning and recombinant expression of the VP28 carboxyl-terminal hydrophilic region from a brazilian white spot syndrome virus isolate

Brazilian Archives of Biology and Technology, 2011
In the present study, a fragment of the VP28 coding sequence from a Brazilian WSSV isolate (BrVP28) was cloned, sequenced and expressed in E. coli BL21(DE3) pLysS strain in order to produce the VP28 carboxyl-terminal hydrophilic region.

Effect of Stocking Densities on Growth Performance of Mud Crab (Scylla olivacea) in the Earthen Pond System in Southwest Region of Bangladesh

Aquaculture, Fish and Fisheries, Volume 6, Issue 1, February 2026.
ABSTRACT Coastal communities in Bangladesh face significant challenges due to long‐term salinity intrusion, leading to economic vulnerability and environmental stress. The remarkable adaptability of mud crabs to saline environments has encouraged coastal farmers to transition from shrimp aquaculture to mud crab fattening as an adaptive strategy ...

An effective white spot syndrome virus challenge test for cultured shrimp using different biomass of the infected papilla

MethodsX, 2019
White spot syndrome virus (WSSV) is one of the most virulent pathogens of cultured penaeid shrimp. Several control strategies are used commonly to mitigate the economic losses caused by the pathogen, such as application of antiviral products at farm ...

Temporal habitat partitioning and resource competition between congenerics: Testing for density-dependent growth and mortality in estuarine shrimp.

PLoS ONE
Habitat partitioning can promote coexistence of closely related competitors. Two congeneric shrimps (brown shrimp, Penaeus aztecus, and white shrimp, Penaeus setiferus) which utilize estuaries in the southeastern U.S.
