This study aimed to examine the cultivation of the brackish-water macroalga Ulvalactuca L., known as a seaweed with a high growth rate, in a land-based cultivation over 30 days using different aquaculture effluents as medium. The used wastewater was provided by four land-based aquaculture...

This proceedings contains 32 papers covering aquaculture, fisheries, fish diseases, effect of environmental pollution on fish, fish feeding and conservation. The first 7 papers discuss the culture, transport and feeding of Clarias gariepinus, Oreochromis niloticus, Benthosema pterotum, Penaeus...

This contains topics on improved performance of lemon fin barb hybrid (Hypsibarbus wetmorei × Barbonymus gonionotus) at elevated salinities; enhancement of microalgal production through bacterial mineralization of ethylene glycol; embryonic and larval development of lemon fin barb hybrid (...

A survey was conducted to obtain up-to-date information and create a knowledge base on pond fish farming, local feed ingredients, and their nutritive properties in Rwanda. Sixty-seven pond-farms were randomly sampled from a population of 112 countrywide. Semi-intensive was the dominant (81%)...

Despite continuing worldwide expansion in production and demand, recent performance in the aquaculture sector in Egypt has been volatile, and yield has reduced. The most significant and visible problems arise from parasitic diseases and predation by birds. In this study, we examine the impact of...

Demand for fish is growing rapidly in Tanzania due to population growth and rising incomes. However, as fewer wild fish are being caught, there is a gap in fish supply. Aquaculture is a viable alternative source to meet the gap in fish demand. Tanzania has the perfect climate and land for fish ...

Potomida semirugata, which belongs to the Unionidae family, require a host fish to complete their life cycle. In this study, the host fish preference of this species was investigated. Besides, mussel species and hence the attachment state of larvae on the host fish were also investigated. Five...

In subsistence and small-scale fish farming, algae are an important food source for fish. Therefore, understanding their distribution and diversity in fish ponds is essential. This study aimed at characterising algae species in African sharptooth catfish (Clarias gariepinus) and Nile tilapia (...

Present research aimed to examine the pathogenicity of some bacteria which were isolated from ponds aquaculture to some freshwater fish. A number of novel pathogenic bacterial strains that infect fish have been identified within the previous five years. Isolating and testing bacteria from culture...

In Chad, Clarias gariepinus (catfish) fishing traditionally in many aquatic ecosystems. Its livestock farming, which can play an important role in the country's economy by improving food self-sufficiency in protein, is still in its infancy. However, fish feeding is the major constraint for the...
