Shrimps remain an important source of proteins worldwide. The contamination of the environments with effluence such as from domestic, healthcare systems, industrial waste discharges and agricultural run-offs; are posin...

One of the many biomarkers for determining the effects of pollutants on fish is changes in organ histopathology. Leaves of Balanites aegyptiaca have been reported to have phytochemicals with fish anaesthetic property. This study sought to...

The desire to shore up the shortfall in protein supply, the increased awareness of the importance of cholesterol free
animal protein, like guineafowl, and the need to conserve their wild genes, have necessitated studies on improved
capti...

The level of heavy metals in water, sediment, water hyacinth (Eichhornia crassipes) and frillfin goby (Bathygobius soporator) from Ologe Lagoon and its tributaries were monitored because of the importance of the water bodies to t...

A survey on the diversity and abundance of earthworms in southwestern Nigeria was carried out. Earthworm and soil samples
were collected from thirty different locations within the sub-region. Earthworms were identified and soil samples were a...

Samples of broiler starter feed, grower mash, broiler finisher feed and layers mash were collected from three commercial feed manufacturers and were coded commercial feed A (CFA), commercial feed B (CFB) and commercial feed C (CFC). The proximate...

Akwa Ibom State is one of the six maritime states in Nigeria and has a shoreline of approximately 129km. Three important rivers (Cross, Imo and Kwa Ibo) transiting through some Nigerian states, terminally pass through the state before discharging...

The menace of microplastics in the aquatic ecosystems is of increasing concern worldwide mainly due to their impact on the entire ecosystem and human health. In order to contribute to knowledge, the incidence of microplastics in water and fish sam...

Benin City, the capital of Edo State of Nigeria has undergone tremendous changes in recent times, especially with the aggressive rate of urbanisation in the last two decades. This has invariably resulted in habitat loss and fragmentation for the a...

The encroachment of freshwater territories by invasive species is a global issue with its associated co-existence, displacement and facilitation of native species. The blackchin tilapia, Sarotherodon melanotheron is one of the most succes...

Benthic macroinvertebrates are helpful bio-indicators providing better understanding of modified and perturbed aquatic ecosystems. This study seeks to determine the ecological status and diversity of the macroinvertebrate community in relation to...

The presence of the West African manatee, Trichechus senegalensis in a semi-wild holding facility in Little Stream Farm, Ibesikpo Asutan Local Government Area, presented an opportunity to study directly, aspects of their biology, which hi...

The decline in animal population with resulting risk of eventual disruption of ecosystem functioning has necessitated moves towards non-invasive sampling methods for ecotoxicological studies. These efforts have focused on developing sampling metho...

Biodiversity is critical for sustainability but it is being increasingly threatened by anthropogenic activities, such as habitats’ degradation through deforestation, unsustainable shifting cultivation and draining of wetlands; as well as ind...

Pesticides from agricultural run-off pose a severe threat to non-target organisms, such as fishes. This study was carried out to evaluate acute toxicity and histological and genotoxic effects (erythrocytic nuclear abnormalities) of lethal and subl...

Streams are often recipients of pollution from agricultural, domestic and industrial sources though they are important sources of water supply and habitats of several aquatic species. Regular monitoring is required to protect this fragile but impo...

Macroinvertebrates are good bioindicators of water quality and ecosystem health and are often used to study anthropogenic effect on aquatic ecosystems. Consequently, some environmental variables and macroinvertebrates of Eme river were studied to...

Plastic pollution is ubiquitous throughout the world’s ecosystem. Increase in the world’s plastic production and use, inefficient recycling, indiscriminate disposal, synthetic nature and non- biodegradability of plastics have made it a...

Iyieke Lake is one of the floodplain lakes within the middle reaches of the Cross River, it is a major foraging and breeding site of several fish species. It is not directly connected to any river, so the water level depends on seasonal inundation...
