The Carp Genetic Improvement Program is the only program of its kind in the world concentrating on catla and silver carp as well as being the largest familybased selection program for rohu. The methods are similar to those used to develop faster growing chickens and livestock that have transformed their respective sectors. This brief highlights the methodology of the carp genetic programs.
Rohu (Labeo rohita) is a significant freshwater aquaculture species with approximately 1.8 Mt produced annually. Fin clips obtained from the founders of a newly established Bangladesh-based breeding population (~140 fish from each of the Halda, Jamuna, and Padma rivers) were used to identify 9157 SNPs and 14 411 silicoDArT markers using the Diversity Arrays Technology (DArT) genotyping-by-sequencing platform known as DArTseq. After quality control, 1985 SNPs were retained and used to examine population structure within and among river systems.
In India’s Odisha State, fish farmers have been able to double their production and increase their profits thanks to a carp intensification program supported by WorldFish.
In terms of quantity produced, Catla catla is the sixth most important finfish aquaculture species produced globally in 2015. It is primarily grown in South Asia, often on a small scale in polyculture with other species. In spite of its economic importance, in a number of countries, including Bangladesh, the quality of catla seed produced in hatcheries has historically suffered from high levels of inbreeding, uncontrolled interspecific hybridisation and negative selection.
The coastal zone of southwest Bangladesh, endowed with diverse resources, bears a significant scope in ensuring security of food and livelihood of the coastal poor people. However, the region is highly prone to adverse weather events and environmental changes leading to vulnerability in the agricultural production as well as food security, and livelihood of the people. The uncertainties of the weather and environmental events in the coastal region often affect the potential aquaculture inputs producing industries like fish seeds.
A wide range of chemical and biological products are used in aquaculture to improve the health status and to prevent or cure diseases of cultured animals. The present study aimed to identify the health issues, management practices and occupational health hazards related to shrimp (Penaeus monodon) and prawn (Macrobrachium rosenbergii) farming in the southwest region of Bangladesh.
The present study was carried out to evaluate the kinetics of antibody titers and protective response against A. hydrophila antigen at different age groups of the two species of Indian major carps, catla (Catla catla) and rohu (Labeo rohita).
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.
Due to inadequate technical knowledge and training in advanced methods of gradually growing carp poly culture, framers are not getting expected yield. From the very beginning of the CSISA-BD project, WoldFish Center has taken initiative to introduce advanced methods in carp poly culture. To do this, the shortage of skilled trainers and training materials, has, particularly, been realized. Presently, a number of manuals on carp poly culture from Department of Fisheries, Bangladesh Fisheries Research Institute, WorldFish Center and different GOs and NGOs are available.
Lack of quality seed and technical knowhow are considered major constraints to improving aquaculture productivity and profitability in Bangladesh. This paper assesses the outcomes of investments in improving carp seed quality and farmer training, targeting poor and women fish farmers, on the productivity and profitability of homestead aquaculture systems in Southwest Bangladesh.
