Fish trait preferences: a review of existing knowledge and implications for breeding programmes

Continued growth of the aquaculture sector will rely on the availability of fish with traits that respond to the needs and preferences of these users along the value chain. Such trait responsiveness requires that fish breeding programmes have reliable knowledge of these users’ trait preferences. The present study found from a non-systematic literature review, that no fish breeding programme had reported user preference in their product-profile design.

Tilapia major clinical signs (Khmer version)

The purpose of this poster is to enhance the capacity of hatcheries, nurseries, grow-out farmers and extension service providers to recognize and report tilapia diseases. Prevention, early recognition, diagnosis and rapid intervention are the best steps to manage aquatic animal diseases. If you observe clinical signs, abnormal behaviour and unusual mortality, contact your local aquaculture health professionals to report and ask for support.

Biosecurity in tilapia production

A presentation given at The World Organisation for Animal Health (OIE) held the 4th Global Conference on Aquatic Animal Health from 2 to 4 April 2019, in Santiago, Chile. Tilapia is very important for food and nutrition security, livelihoods and income for rural households in Asia and Africa. Importance attached to biosecurity and health management must be at the same level as for shrimps and salmon. This calls for a massive change in the way farmers, researchers and policy makers treat carps and tilapia with respect to overall biosecurity and health management.

Typology of interventions aiming to reduce antimicrobial use (AMU) in aquaculture systems in low and middle-income countries

This poster aims to conduct a typology analysis of interventions to reduce antimicrobial use (AMU) in aquaculture systems of low and Aim middle income countries and provide an overview of the policy landscape affecting AMU. Poster presented at the Second international conference - Quantification, Benchmarking and Stewardship of Veterinary Antimicrobial Usage, held in Bern, Switzerland from 2-3 July 2019.

Assessment of the impact of dissemination of genetically improved Abbassa Nile tilapia strain (GIANT-G9) versus commercial strains in some Egyptian governorates

WorldFish initiated a selective breeding program in Abbassa--Egypt to develop and produce the genetically improved Nile tilapia strain known as “Genetically Improved Abbassa Nile tilapia (GIANT)”, adopting the same technology used for the Genetically Improved Farmed Tilapia (GIFT), in Asia. WorldFish provided the Ninth Generation (G9) broodstock of the GIANT to 11 Broodstock Multiplication Centers (BMC’s) in five governorates; these centres then disseminated improved mixed-sex fry to 160 tilapia hatcheries which supplied all-male fry to 1,500 fish farms in 2017.

Masa depan akuakultur di Indonesia: Transformasi menuju peningkatan keberlanjutan = The future of aquaculture in Indonesia: A transformation toward increased sustainability (Indonesian version)

Untuk memerangi tingkat kekurangan gizi dan stunting atau kekerdilan saat ini, pemerintah Indonesia telah menetapkan suatu target ambisius untuk pertumbuhan akuakultur di Indonesia hingga tahun 2030. Perikanan secara fundamental telah memberikan kontribusi pada kesejahteraan Indonesia dengan memberikan sumber protein tinggi yang terjangkau. Namun untuk mencapai target yang telah ditentukan, hasil produksi harus ditingkatkan lebih dari tiga kali lipat. Namun bagaimanapun, dalam memenuhi target produksi tersebut akan timbul suatu dampak pada lingkungan.

The future of aquaculture in Indonesia: A transformation toward increased sustainability

To combat current high levels of malnutrition and stunting, the Indonesian government has set ambitious targets for aquaculture growth up to 2030. Fish already fundamentally contributes to the well-being of Indonesians by offering an affordable source of nutritious animal protein. However, to reach these targets, production will have to more than triple. However, meeting the production targets will come at a cost for the environment.

Dietary administration of probiotics modulates non-specific immunity and gut microbiota of Nile tilapia (Oreochromis niloticus) cultured in low input ponds

Poor culture conditions in low input ponds make fish highly susceptible to infectious pathogens which lead to diseases and mortalities yet the effects of probiotics on immunity, gut microbiota and microbiological quality of fish in low input ponds are unknown. Nile tilapia, Oreochromis niloticus fingerlings (40 g) were randomly stocked at 50 fish m-3 in 1.25 m3 cages in low input ponds. The fish were fed on diets supplemented with either Saccharomyces cerevisiae (1 × 1010 CFU g-1) or Bacillus subtilis (1 × 109 CFU g-1) at six levels: Diet 0 (No probiotic); S.

Controlling preharvest maturity in farmed Arctic char: A review from the Canadian perspective

Arctic char, Salvelinus alpinus L. is a promising candidate for aquaculture expansion in Northern Europe, Canada, and the United States because of its excellent growth at low temperature, tolerance to high rearing density, high fillet yield, and superior flesh texture and flavor. To support this industry, several breeding programs in these regions currently focus on selection for growth and delayed maturation. While the growth potential of existing strains has been improved, preharvest sexual maturation remains a problem in this industry.
