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

Acute toxicity of Euphorbia kamerunica on Oreochromis niloticus

Ecotoxicology and Environmental Safety, 2005
A series of static short-term bioassays was conducted to assess the acute toxicity of the plant Euphorbia kamerunica on the fingerlings of Oreochromis niloticus. The 96-h LC(50) was computed using two methods: probit analysis and the arithmetic graphic method. The overall mean value of 0.023 +/- 0.002 g/L was obtained.

Impacts of Salinity on Growth, Physiology and Tissue Integrity of Nile Tilapia: Implications for Coastal Aquaculture Under Climate Change

Aquaculture, Fish and Fisheries, Volume 6, Issue 3, June 2026.
ABSTRACT Climate change is responsible for salinity intrusion in coastal areas, which is significantly threatening the sustainability of aquaculture. This investigation focused on evaluating growth performance, proximate composition, blood morphology and histopathological modifications in Nile tilapia (Oreochromis niloticus) exposed to varying salinity

Effect of Stocking Density on Growth Performance and Economic Return of Nile Tilapia (Oreochromis niloticus) in Non‐Aerated Semi‐Intensive Ponds of Bangladesh

Aquaculture, Fish and Fisheries, Volume 6, Issue 3, June 2026.
Effect of stocking density on growth performance and economic return of Nile tilapia cultured in non‐aerated semi‐intensive ponds in Bangladesh. Four stocking densities (200, 230, 260, and 300 fish decimal−1) were evaluated over a 243‐day culture period.

The impacts of biological invasions

Biological Reviews, Volume 101, Issue 3, Page 1255-1310, June 2026.
ABSTRACT The Anthropocene is characterised by a continuous human‐mediated reshuffling of the distributions of species globally. Both intentional and unintentional introductions have resulted in numerous species being translocated beyond their native ranges, often leading to their establishment and subsequent spread – a process referred to as biological

Beyond mammals: the evolution of chewing and other forms of oropharyngeal food processing in vertebrates

Biological Reviews, Volume 101, Issue 3, Page 1406-1462, June 2026.
ABSTRACT Oropharyngeal food processing exhibits a remarkable diversity among vertebrates, reflecting the evolution of specialised ‘processing centres’ associated with the mandibular, hyoid, and branchial arches. Although studies have detailed various food‐processing strategies and mechanisms across vertebrates, a coherent and comprehensive terminology ...
