The Thai Fish Project began in 2019, and involves around 200 research members and multiple institutions in Thailand and Japan. The project aims to promote domestication and wise use of two Thai native aquatic species, namely the Asian sea bass Lates calcarifer and banana shrimp Penaeus merguiensis through increasing productivity, reducing the impact of infectious diseases, and preserving genetic resources. The project also encompasses several specific research topics to ensure that it comprehensively addresses the concerns on safeguarding the food security and enhancing the environmental sustainability as much as possible. This article describes the main research activities, outputs and future expectations of the Thai Fish Project.

Naihati fish seed market of West Bengal was established in 1976 and is the largest seed market in India. With the advent of induced breeding technology and hatcheries, fish seed is now available almost year-round, catering to the need of Indian farmers. Situated in North 24 Parganas, Naihati wholesale fish seed market is a well-known establishment that provides multifaceted services to stakeholders including fish seed growers, retailers, sellers, and mediators. This article describes the state of the market as aspects of its evolution over time.

In late 2022 tilapia parvovirus (TiPV) was found to be associated with mass mortalities of tilapia in Odisha, India, both individually and in co-infections with tilapia lake virus. Infections have also been reported from Thailand and China. Clinical signs include lethargy, scale loss, redness on the body with haemorrhages on the operculum, base of fins and ventral part, opaqueness of the eyes, swimming near the pond edge and loss of appetite before death. This article describes the epidemiology of TiPV disease including its diagnosis, transmission, prevention and control, and its potential impact on the tilapia aquaculture industry.

The Late Sri Kripan Sarkar was an enterprising ornamental fish breeder-cum-farmer par excellence, exporter and supplier of the same from northern part of West Bengal. As proprietor of Rainbow Ornamental Fish Farm, at Bakshipara Village in Jalpaiguri District, he was an expert and authority in scientific breeding, larval rearing, propagation, research and experimentation on economically important freshwater ornamental fishes. There was a time when Sri Sarkar was the only commercial ornamental fish breeder in north Bengal. This article documents his experiences and career as an influential pioneer in the ornamental fish culture trade.

The welfare of decapod crustaceans, the largest group of farmed animals worldwide, is gaining prominence in the aquaculture industry. Taking better care of the billions of shrimp farmed annually not only responds to certification standards and consumer demand, it is the right thing to do. Embracing a welfare approach has the potential to address current challenges in shrimp farming by providing insights into farming conditions and animal health, ultimately boosting production performance. Recording welfare data enhances transparency along the supply chain, ensuring that every actor, from hatcheries to shrimp buyers, understands the quality of the breeder, post larvae, or shrimp they purchase. This article also details a free online training course on shrimp welfare created by FAI Farms.

With the implementation of the new aquatic animal disease reporting in the Asia Pacific region from January 2021, and in lieu of the published QAAD Reports (last issue published was 4th quarter of 2020), NACA is publishing reported aquatic animal diseases submitted by countries in the Asia-Pacific region. This report covers the second quarter of 2023 and the original and updated reports can be accessed from the QAAD page

In this issue:

Kingdom of Saudi Arabia joins NACA; Applications for the position of Director General, NACA; NACA awarded the Aziz-Ul Haq Rural Development Medal; Training Course on Risk Analysis in the Aquaculture Value Chain held in Bangkok; Free FAO publication: Genetic management of Indian major carps; 7th International Symposium on Cage Aquaculture in Asia; PhD scholarships: Shanghai Ocean University PhD Programme 2024; WAS Journal Special Issue: Global Conference on Aquaculture Millennium +20 Thematic Reviews; Seminar on Artemia Research and Production: Videos; Reported aquatic animal diseases in the Asia-Pacific Region during the first quarter of 2023.

Eight thematic reviews prepared as preparation for the Global Conference on Aquaculture Millennium +20 (GCA +20) have been published in a Special Issue of the Journal of the World Aquaculture Society "Aquaculture for Food and Sustainable Development". A group of experts prepared advanced working drafts of each thematic review and the key findings from each theme were presented and discussed by expert panels during the GCA +20. Participants were then invited to provide their feedback and perspectives on the reviews and their key messages for consideration in finalisation of the papers. The reviews are available for free download.

CAA7 will be held in Hainan, China, from 29 November to 2 December, with an option for online participation via Zoom for people that cannot attend in person. The theme of the symposium is "Sustainable development of cage aquaculture in Asia". Sessions will be held on: Production systems; breeding and seed production; nutrition and feed; carbon sink and fouling organisms; health and environmental management; economics, gender, livelihood and policy.

The symposium is organised by the Asian Fisheries Society, Hainan University, Shanghai Ocean University, and the China-ASEAN "Belt and Road" Joint Laboratory of Mariculture Technology, Center for Ecological Aquaculture.

Collectively carps represent the largest global aquaculture sector, contributing over 20 percent of global aquaculture production. The Indian major carps including catla (Catla catla), rohu (Labeo rohita) and mrigal (Cirhinnus mrigala) are cultured widely across the Indian sub-continent with the main culture system being a multi-species polyculture in ponds, often including other carp species. This production sector is supported by major seed supply systems producing over 50 billion seed per annum. This case study analyses genetic management of Indian major carps since they were first domesticated with the development of hypophysation techniques in the 1950s. A review of literature and a survey of common hatchery practices identifies significant problems prevalent in the sector brought about by a lack of application of best practices in genetic management resulting in loss of genetic diversity, inbreeding and uncontrolled hybrid introgression.
