Comparing genomic signatures of selection between the Abbassa Strain and eight wild populations of Nile tilapia (Oreochromis niloticus) in Egypt

Domestication to captive rearing conditions, along with targeted selective breeding have genetic consequences that vary from those in wild environments. Nile tilapia (Oreochromis niloticus) is one of the most translocated and farmed aquaculture species globally, farmed throughout Asia, North and South America, and its African native range. In Egypt, a breeding program established the Abbassa strain (AS) of Nile tilapia in 2002 based on local broodstock sourced from the Nile River.

Replication Data for: A systematic literature review of the major factors causing yield gap by affecting growth, feed conversion ratio and survival in Nile tilapia (Oreochromisniloticus)

Productivity among small- and medium-scale tilapia farms varies considerably. The difference between the best performers and lower ones (yield gap), is affected by differences in growth rate and feed conversion ratio (FCR). FCR at the farm level is strongly influenced by survival of fish. In this study a systematic literature review of two databases (ASFA and CAB-Abstracts) identified 1973 potentially relevant articles.

An on-Farm Performance Assessment of Aquaculture Production Systems in Nigeria

The survey was implemented to assess on-farm performance of aquaculture fish production systems in Nigeria. The primary sampling unit was aquaculture farming households/farms. The survey comprised the following modules: (1) farmer characteristics; (2) aquaculture production and marketing activities including input use and cost as well as output harvested and sold; (3) Aquaculture experience, change and livelihoods; (4) aquaculture credit and association; (5) food safety and willingness to participate in aquaculture certification; Data on aquaculture production were collected at farm level.

Nigeria: post-farmgate value chain (wholesalers, processors, and retailers) scoping study dataset

Nigeria is the largest fish producer in Sub-Sahara Africa. Fish plays crucial role to support fish producers and post-farm gate value chain actors’ livelihood. Despite the virtues of aquaculture and fisheries sub-sectors to enhance value chain actors livelihood, major gaps exist related to fish value chain efficiencies, including financial performance of post-farmgate actors, gender-disaggregated data on value chain actors, the roles of women and youth in fish trade, and post-farmgate food safety practices.
