Nonapeptide molecular evolution during the adaptive radiation of Tanganyika cichlids

Journal of Neuroendocrinology, Volume 38, Issue 6, June 2026.
Abstract Oxytocin (OT) and vasotocin (VT) are evolutionarily conserved nonapeptides that regulate a wide range of physiological and behavioral processes in vertebrates. Their receptor families have undergone gene duplications that facilitated functional diversification throughout vertebrate evolution.

Photoperiod modulates male sexual maturation in the Emperor tetra (Nematobrycon palmeri), a strictly tropical ornamental fish

Journal of the World Aquaculture Society, Volume 57, Issue 3, June 2026.
Abstract Photoperiod manipulation is widely used to regulate reproduction in temperate fish species, but little is known about its effects in strictly tropical species. This study evaluated whether the Emperor tetra (Nematobrycon palmeri), a tropical ornamental fish, can modulate sexual maturation in response to artificial light regimes.

Molecular validation of Cichlids from Zobe Reservoir, Dutsin-Ma, Katsina State, Nigeria using Cytochrome Oxidase (COI) Genes

Fountain Journal of Natural and Applied Sciences (FUJNAS)
The species of cichlids are easily misidentified due to their morphological similarities. This study, therefore, was designed to discriminate the cichlid species inhabiting Zobe reservoir using a molecular approach.

Fish health, environmental contaminants, and disease management in Ghanaian aquaculture: A systematic review

Journal of the World Aquaculture Society, Volume 57, Issue 3, June 2026.
Abstract Fish health significantly influences aquaculture productivity, sustainability, food security, and public health. Despite Ghana's rapid aquaculture expansion, the sector remains constrained by widespread disease outbreaks and environmental threats. This systematic review synthesizes existing literature (2010–2024) to comprehensively assess fish

Induction of putative tetraploid larvae and analysis of unfertilized egg storage for burbot (Lota lota)

Journal of the World Aquaculture Society, Volume 57, Issue 3, June 2026.
Abstract Burbot (Lota lota) are a promising candidate for commercial aquaculture production. Methods for captive culture are well understood, the species is highly regarded for its muscle, roe, liver, and skin, and its resistance to many salmonid pathogens coupled with the species' affinity to trout‐like water quality conditions make burbot an ...

Effects of dietary 1,8‐cineole supplementation on growth performance, antioxidant, and immunological responses of Nile tilapia, Oreochromis niloticus, reared in different stocking densities

Journal of the World Aquaculture Society, Volume 57, Issue 3, June 2026.
Abstract This study aimed to evaluate the effects of dietary 1,8‐cineole (CIN) on Nile tilapia, Oreochromis niloticus, reared at different stocking densities. Fish (average initial weight 13.2 ± 0.35 g) were fed diets supplemented with 0%, 0.25%, or 0.5% CIN and stocked at either 14 (normal) or 56 (high) fish per 120‐L tank.

Impact of diet, dissolved oxygen concentration, and stocking density on channel catfish (Ictalurus punctatus) production performance

Journal of the World Aquaculture Society, Volume 57, Issue 3, June 2026.
Abstract Diet selection, stocking density, and target levels for dissolved oxygen concentration are three of the major management decisions made by aquaculture producers. These factors and their combinations were tested in channel catfish (Ictalurus punctatus) to determine their relative impact on food conversion ratio (FCR), growth performance, and ...
