Abstract This study was conducted to evaluate the effects of probiotic‐amended diets fed juvenile Nile tilapia, Oreochromis niloticus , on growth and susceptibility Streptococcus iniae infection. Fish (average weight 16.5 ± 0.2 g) were five formulated with Bacillus subtilis strains SB3086 SB3295 SB3615 or AP193 either individually in combination at a targeted concentration approximately 4 × 10 7 colony‐forming units ( CFU )/g feed basal control diet no additives for 21 d. After 21‐d trial,...
The high dependence on plastics in Ghana has resulted the generation of large quantities plastic waste which are poorly managed and improperly disposed into aquatic environments. This study assessed spatial distribution abundance microplastics mangrove oysters (Crassostrea tulipa): a major fishery resource commercial importance Ghana. results showed that 84.0% all individuals examined had ingested microplastics. A total 276 microplastic items were recovered from 120 individual oysters. Densu...
Pollution of plastic waste in aquatic ecosystems Ghana is significant concern with potential adverse effects on food safety and ecosystem function. This study examined the abundance distribution microplastics (MPs) freshwater biota samples namely: African river prawn (Macrobrachium vollenhovenii), Volta clam (Galatea paradoxa), Nile tilapia (Oreochromis niloticus), sediment from Lake. Both were subjected to microscopic identification FTIR analysis. In samples, highest mean microplastic 4.7 ±...

The use and misuse of antibiotics for treating animal human infections are a key driver the emergence resistant bacterial strains at human-animal-environment interface. This inappropriate threatens ecological balance poses significant risk to health. lack relevant knowledge right attitudes practices regarding antimicrobial stewardship among fish farmers, antibiotic drug retailers, government agencies has significantly exacerbated this serious environmental public health issue. To enhance...
This study was conducted to evaluate the individual and combined effects of long-term feeding diets containing two probiotic Bacillus subtilis group strains (Aqua NZ AP193) prebiotic Previda®, a commercial hemicellulose extract, on growth performance, immune parameters Aeromonas hydrophila susceptibility juvenile Nile tilapia, Oreochromis niloticus. tilapia average weight 7.47 ± 0.11 g were fed formulated with probiotics and/or prebiotic, or control diet for 8 weeks and, subsequently,...
This global survey of vAh brought together scientists that study fish disease to evaluate the evolution, geographical distribution, phylogeny, and hosts other Aeromonas sp. isolates. In addition isolates from China United States, four new were isolated lower Mekong River basin in Cambodia Vietnam, indicating significant threat modern aquaculture need for improved biosecurity prevent spread.
Antibiotic residue in food products and the resulting antibiotic-resistant bacteria represent a significant global public health threat. The misuse of antibiotics is primary contributor to this issue. This study investigated knowledge, attitudes, practices (KAP) regarding antibiotic use among cage fish farmers on Ghana's Volta Lake.
Aquaculture is considered an alternative to making up the shortfall in supply of fish Ghana. The Cobb-Douglas production function, which relates output several independent input variables, was used determine inputs that affect productivity. A survey conducted on pond farmers selected from four regions Empirical results show stocking rate as most significant affected production. exhibited increasing returns scale over period study, meaning increase will more than proportionately output....
Small-scale on-farm storage of maize in Africa is changing, part due to shifts the threat from insect pests. A questionnaire survey 242 households four closely situated districts Volta Region Ghana, where Prostephanus truncatus (Horn) (Coleoptera: Bostrichidae) arrived ten years ago, was used show how practices have changed over last five years. The included asking farmers about changing use contact insecticides order guide research and future recommendations. We found high uptake...
The ability to access user-friendly, low-cost instrumentation remains a limiting factor in coastal ocean observing. majority of currently available marine observation equipment is difficult deploy, costly operate, and requires specific technical skills. Moreover, harmonized program for the world’s waters has not yet been established despite efforts global organizations. Global observational systems are mainly focused on open do include shelf areas, where models satellites require large data...
Abstract 1 Attack by Prostephanus truncatus (Horn) (Coleoptera: Bostrichidae) on the maize and cassava stored small‐holder farmers in Africa is sporadic, varying considerably within between years. The risk that food store will become infested related to number of beetles dispersing flight. A means predicting years with high dispersal rates needed warn when be vigilant. 2 relationship climatic variables pheromone trap catches was observed a forest‐savannah transition zone Ghana. These...
Lakes around the world, including Ghana’s Lake Volta, are facing insidious threats from pollutants due to high dependency on aquatic ecosystems. Cage aquaculture is expanding across Africa because of its potential address food insecurity, provide livelihoods, and boost local economies. However, uncontrolled expansion cage can have significant negative impacts water resources, environmental footprints that threaten biodiversity. Given intensification for tilapia farming we advocate a...
Education, research, and biosecurity have global recognition as strong pillars of sustainable aquaculture development. In many developing countries, insufficient knowledge awareness among stakeholders regarding the relevance education, influenced sustainability negatively. To uncover gaps in practices aquatic animal health management, we conducted a questionnaire-based study various East West African countries. By adopting methodology self-reporting data, invited significant number...
