Report of the SDG-aligned Artemia Aquaculture Workshop

Annual consumption of Artemia is now estimated at 3,500 – 4,000 tonnes, underpinning the production of over 900 billion crustacean post larvae and fish fry. With approximately 90 percent of the current Artemia production harvested from inland salt lakes, the future of the hatchery industry could be at risk and requires urgent attention. The purpose of the workshop was to explore needs and opportunities for a new international initiative to guarantee a more sustainable provision of Artemia, both from natural sources and from controlled extractive Artemia farming integrated with salt production and other fish/crustacean aquaculture.

Research breakthrough seen to curb shortage of "poor man’s fish"

A scientific breakthrough at a research center in the Philippines might finally be the long-term solution to the perennial shortage of round scad (Decapterus spp.), known as the “poor man’s fish” in the country. In a world’s first, researchers successfully spawned the round scad Decapterus macrosoma in captivity at the Southeast Asian Fisheries Development Center, Aquaculture Department (SEAFDEC/AQD) in Tigbauan, Iloilo, marking a critical milestone towards farming the fish, locally known as galunggong. Round scad is considered a staple fish in the Philippines with over 202,000 metric tons harvested by commercial and municipal fisheries in 2020 according to government statistics.

Magical role of live foods in boosting spawn survival of climbing perch: A success in the farmer’s field

Climbing perch inhabit water bodies ranging from fresh to brackish waters across a wide range of environments, and are widely distributed throughout south and southeast Asia through to southern China. In India it is prized both as a foodfish and as a traditional medicinal food. This article describes the induced breeding of climbing perch and the interaction of scientists and farmers to improve survival of larvae and fry in through the use of live feeds (rotifer) in small-scale hatcheries in India.

Aspects of air-breathing fish farming practiced at Mathurapur-II Block, West Bengal, India

Climbing perch Anabas testudineus is a high-priced fish, nutritious and economically profitable for small- to medium-scale fish farmers, who can obtain fry from local paddy fields and low-lying inundated areas in late summer, monsoon and post-monsoon periods. Climbing perch is a facultative air-breathing fish that is able to move between water bodies by undertaking short migrations overland. This article describes techniques for climbing perch and major carp aquaculture, including use of biofloc systems, preparation of live feeds including mealworms, and some concerns regarding the hybridisation of native Indian strain of A. testudineus with an imported Vietnamese strain.

Wild seed collection and modified-extensive farming of Mystus gulio in inland water bodies of South 24 Parganas, West Bengal

The cultivable small- to medium-sized bagrid catfish Mystus gulio is an estuarine species sold as a high-priced food fish in retail markets in cities and towns of southern West Bengal. M. gulio is a good addition to mixed species culture-based fisheries in canals in the Indian Sundarbans region. It adapts and grows well in freshwater ponds and is recommended for freshwater fish culture in areas of the Sundarbans vulnerable to saline water intrusion. This article describes the seed collection, nursery and grow-out practices of M. gulio as practiced in modified-extensive mixed culture systems in West Bengal, India.

Habitat breeding and seed rearing of a near threatened featherback, Chitala chitala

The humped featherback, Chitala chitala is considered to be one of the most commercially important food, sport, aquarium and highly priced cultivable fish in Assam. However, over exploitation, habitat degradation and pollution has caused wild populations to decline in recent decades, to the point where the species is categorised as Near Threatened on the IUCN Red List. Here we present the biological aspects of breeding and larval rearing protocols of the humped featherback, which has been prioritised as a new candidate species for freshwater aquaculture in India. The information will also aid in stock enhancement and conservation of this species.
