Effects of Carbon‐to‐Nitrogen Ratio in Biofloc System on Water Quality, Growth Performance and Haematological Parameters of Nile Tilapia (Oreochromis niloticus)

Aquaculture, Fish and Fisheries, Volume 6, Issue 3, June 2026.
ABSTRACT A 10‐week indoor culture trial was carried out to assess the impact of various C/N ratios on the water quality, growth performance and haematology of Nile tilapia (Oreochromis niloticus) in a biofloc system. The experiment included four biofloc treatment groups with distinct C/N ratios (12:1, 15:1, 18:1 and 21:1) and a control group with a C/N

Gonado-hepatosomatic Indexes of Clarias gariepinus Sub-adult Exposed to Artrazine, Cocos nucifera Water and Phyllanthus muelarianus Extract [PDF]

Journal of Aquaculture Research & Development, 2015
Success in fish culture is influenced by several factors. Elucidation of influences of some of these factors has become necessary as there is a lingering need to narrow the gap between supply and demand in the fish market in Nigeria. The influence of Atrazine (a systemic herbicide), coconut water (Cocos nucifera: also called coconut milk due to its ...

Growth and immunomodulation in individually reared giant freshwater prawn, Macrobrachium rosenbergii (de man 1879) as a function of dietary chitosan extracted from black soldier fly (Hermetia illucens) larvae and shrimp shell

Journal of the World Aquaculture Society, Volume 57, Issue 3, June 2026.
Abstract Macrobrachium rosenbergii is one of the major species produced in world aquaculture. Functional feed additives can contribute to the sustainable production of prawns, and chitosan is one of the additives, which is widely used for various applications, including improving growth and immunity in aquatic species. One of the sources, black soldier

Evaluation of physiological and molecular tools to assess ovarian stages in the black tiger prawn (Penaeus monodon)

Journal of the World Aquaculture Society, Volume 57, Issue 3, June 2026.
Abstract Advancing knowledge of the molecular mechanisms governing vitellogenesis and spawning in the black tiger prawn, Penaeus monodon, requires an efficient method for identifying ovarian stages. Several physiological and molecular tools have been employed to define these stages in laboratory studies.

Microplastic Impacts on Seafood: A Global Synthesis of Experimental Findings

Fish and Fisheries, Volume 27, Issue 3, Page 591-606, May 2026.
ABSTRACT Plastic pollution is a growing global concern, with plastic and microplastic particles now widespread in aquatic environments. Microplastics are frequently ingested by marine organisms, including commercially important seafood species. Ingestion can lead to a range of biological effects, influenced by the size, type and quantity of plastic, as

The Individual and Combined Effects of Warming and Atrazine on Lithobates pipiens Phenotypes: Implications for Frog Declines

Journal of Experimental Zoology Part A: Ecological and Integrative Physiology, Volume 345, Issue 3, Page 238-258, April 2026.
ABSTRACT Amphibians are the most threatened vertebrate class globally. Climate change, agrochemicals, and/or pathogens and parasites are implicated in contributing to amphibian declines, either singly or in combination. We investigated individual and combined effects of elevated temperatures and atrazine (2.0 μg/L) on Lithobates [formerly Rana] pipiens

Dietary supplementation with ALLPRO, a DHA source, for Nile tilapia reared under field conditions throughout cold season: Effects on growth performance, carcass and fillet quality, and economic feasibility

Journal of the World Aquaculture Society, Volume 57, Issue 2, April 2026.
Abstract This study evaluated the effects of dietary supplementation with ALLPRO, a source of docosahexaenoic acid (DHA—C22:6n‐3, 126 g kg−1 dry weight) and nucleotides (5 g kg−1 dry weight), on Nile tilapia farmed in southern Brazil during autumn, winter, and spring.
