Fish in food systems in Nigeria: A review

In Nigeria, like many coastal developing countries, fish is an important source of food for the population, which is currently estimated at 186 million people (World Bank 2016). A recent study estimated that Nigeria ranks third globally for the number of people dependent on coastal fisheries for food and nutrition security, and the demand for fish is growing, alongside growth in population and incomes. However, household fish consumption in Nigeria—measured at 13.3 kg/capita/year—is low compared with the world’s average of 20.3 kg/capita/year (FAO 2018).

Identifying hotspots for antibiotic resistance emergence and selection, and elucidating pathways to human exposure: Application of a systems-thinking approach to aquaculture systems

Aquaculture systems are highly complex, dynamic and interconnected systems influenced by environmental, biological, cultural, socio-economic and human behavioural factors. Intensification of aquaculture production is likely to drive indiscriminate use of antibiotics to treat or prevent disease and increase productivity, often to compensate for management and husbandry deficiencies. Surveillance or monitoring of antibiotic usage (ABU) and antibiotic resistance (ABR) is often lacking or absent.

The complete mitochondrial genome of a Pabdah catfish, Ompok pabda (Hamilton, 1822)

The complete mitochondrial genome of Pabdah catfish, Ompok pabda (Hamilton, 1822) was determined by MiSeq platform. The genome was 16,512 bp in length, in which canonical 13 protein-coding genes, 22 tRNAs, 2 rRNAs, and a control region (D-Loop) were encoded. The overall A + T (55.10%) content was higher than G + C (44.90%). Total nine genes were located at the L strand, and remaining 28 genes were at the H strand. The start codon of 12 protein-coding genes was ATG, except for COX1 (GTG).

AMFORA: Applying a One Health systems modelling approach to formulate strategies for mitigating the risk to human health of ABR in aquaculture

Aquaculture systems are highly complex and influenced by environmental, biological, cultural, socio-economic and human behavioural factors. The growing importance of aquaculture is fuelling a transition of small-scale farming to industrial intensification in LMICs. Two interdisciplinary workshops were held in 2018, in Vietnam and Egypt. They aim to use a ‘systems-thinking’ approach to map aquaculture systems and identify potential hotspots for the emergence and selection of resistance and human exposure to antibiotics and antibiotic-resistant organisms.

Environmental impact of non-certified versus certified (ASC) intensive Pangasius aquaculture in Vietnam, a comparison based on a statistically supported LCA

Pangasius production in Vietnam is widely known as a success story in aquaculture, the fastest growing global food system because of its tremendous expansion by volume, value and the number of international markets to which Pangasius has been exported in recent years.

Value-chain analysis: an assessment methodology to estimate Egyptian aquaculture sector performance

Egypt's aquaculture production (705,490 tonnes in 2009) is by far the largest of any African country and places it 11th in terms of global aquaculture production. The aquaculture sector in Egypt is now a mature one having developed over a period of more than 30 years, but the financial performance of the sector is not well understood or documented, even though value-chain analysis provides a methodological tool to do so.

Cage-pond integration of African catfish (Clarias gariepinus) and Nile tilapia (Oreochromis niloticus) with carps

Cage-pond integration system is a new model for enhancing productivity of pond aquaculture system. A field trial was conducted using African catfish (Clarias gariepinus) and Nile tilapia (Oreochromis niloticus) in cages and carps in earthen ponds. This study aimed to assess the production and profitability of different cage-pond integration models of Nile tilapia and African catfish with carps under farmers’ conditions and to recommend the best ones for adoption in Nepal.

Production economics of striped catfish (Pangasianodon hypophthalmus, Sauvage, 1878) farming under polyculture system in Bangladesh

Fish is the main animal-source food consumed, accounting for 60% of animal protein intake and is the most frequently consumed nutrient rich food in Bangladesh Pangasius is now the most consumed fish in rural areas of Bangladesh. Pangasius aquaculture has improved access to fish among poor consumers in Bangladesh by increasing supply and reducing relative prices. The present study assesses the production costs, profitability and the importance of inputs (seed, feed, fertilizer and labor) in striped catfish (Pangasianodon hypophthalmus) production under polyculture system in Bangladesh.

Mycoflora and mycotoxins in finished fish feed and feed ingredients from smallholder farms in East Africa

In this article, the authors provide a pioneer snapshot of the co-occurrence of aflatoxins, fumonisin and ochratoxin A, as well as other mycotoxins, in fish feed and ingredients from East Africa. A total of 52 samples of finished fish feeds and ingredients were collected from smallholder farmers in Kenya, Tanzania, Rwanda and Uganda, and analyzed.
