The first ever IAAC conference was a free half day event held in Ostend, Belgium on 9 September, as a prelude to Larvi 2024, which ran from 9-12 September. The conference featured twelve presentations introducing the IAAC and providing an overview of many of the issues surrounding Artemia, including management of salt lakes habitats that still provide the bulk of global Artemia supplies, Artemia biodiversity, hatching optimisation, and aquaculture of Artemia biomass in tanks and ponds. Video recordings of most will be posted shortly (the programme below will be updated with links). Video recordings of the presentations are now available on the NACA YouTube channel.

The first IAAC Members’ Meeting was held in the afternoon following the IAAC Conference. The proceedings involved two panel discussions, by the Academic Sector and Private Sector respectively. The panels included remote members participating via Zoom.

14th Asian fisheries and Aquaculture Forum: Early bird closes 10 November https://enaca.org/?id=1366

The 14th Asian Fisheries and Aquaculture Forum (14AFAF) will be held from 12-15 February 2025 in New Delhi, India. Submission of abstracts has been extended until 5 November, and early bird registration closes on 10 November, so get in quick!

The forum is a scientific meeting organised by the Asian Fisheries Society (AFS) once every three years to understand the global trends and address issues and challenges faced by the fisheries and aquaculture sector. The main purpose of this Forum is to provide an international platform for eminent scientists, young researchers, and other stakeholders across the globe to share their research experiences and innovative ideas. By facilitating the exchange of diverse range of knowledge and expertise, the Forum with the Theme ‘Greening the Blue Growth in Asia-Pacific’ aims to address key issues towards developing sustainable fisheries and aquaculture.

Captive breeding of Ompok bimaculatus (pabda): An indigenous catfish of North East India https://enaca.org/?id=1354

Ompok bimaculatus, locally known as pabda catfish, is widely distributed in the natural water resources of Assam and other northeastern states of India. It is a preferred indigenous non-airbreathing catfish with high market demand compared to Indian major carps and exotic carps. Due to habitat modification and over exploitation, pabda has been assessed as Near Threatened by the International Union for Conservation of Nature. This article describes the development of captive breeding protocols for pabda at the Pabhoi Fish Farm, including broodstock management, captive breeding, and larval rearing. Fecundity ranged from 20,000-22,000 eggs per 100 g body weight. Spawning was induced with Ovatide and eggs transferred to a flow-through system for hatching. Larvae began exogenous feeding after two days.

Exploring the possibility of captive production of a near threatened catfish, Rita chrysea for Indian aquaculture https://enaca.org/?id=1345

Rita chrysea, a member of the Bagridae family, is a medium-sized freshwater catfish predominantly inhabiting the Mahanadi River system, coursing through the states of Chhattisgarh and Odisha in India. It has been classified as Near Threatened by the IUCN. Researchers at ICAR-CIFA, Bhubaneswar, have achieved successful breeding and rearing of R. chrysea in an intiative that aims to to popularise the species through training programs for farmers. This article describes methodologies to induce spawning and rear the larvae of R. chrysea and its performance in captivity, potentially paving the way for its adoption as a mainstream aquaculture species. Furthermore, the insights provided in this article may contribute to ensuring the captive breeding and rearing of two other species, R. pavimentata and R. rita, in the future. These species, belonging to the same genus, dominate Indian river systems.

Community participation in marine ornamental aquaculture: Empowerment of women and conservation of reef ecosystems at the Lakshadweep Islands https://enaca.org/?id=1343

Promoting and encouraging community participation in marine ornamental aquaculture presents an alternative approach to enhancing the economic status of marginalised individuals, particularly women, in the Lakshadweep islands. Additionally, it aids in curbing the wild capture of marine ornamental organisms, thereby relieving pressure on natural resources. The article examines the strategy of community-based marine ornamental aquaculture and its significance in bolstering the economy of islanders, particularly women, in the Lakshadweep Sea. It seeks to investigate effective approaches to promote the sustainability of the coral reef ecosystem in the region. High-value marine ornamental organisms, such as fishes and shrimps, are cultivated in community aquaculture units using simplified technology. These organisms are supplied to aquarists and hobbyists, thus supplementing the income of local women islanders.

The Grass Carp Aquaculture Manual https://enaca.org/?id=1338

This manual covers everything from grass carp's natural distribution and reproductive behaviours to its biology and anatomy. This manual also explores diseases that can affect grass carp and emphasises the crucial connection between animal welfare and stress in fish. With a detailed discussion on cultivation systems, this manual includes pond structures and fish farming techniques in both polyculture and monoculture. It provides practical insights into important aspects such as water quality monitoring, feeding, nutrition, health checks and behaviour assessments at every stage of grass carp farming – from broodstock management to pre-slaughter and slaughter processes. The emphasis is on responsible harvesting techniques, transportation considerations and humane slaughter methods. This manual offers a comprehensive guide for both novice and experienced fish farmers, and enthusiasts interested in cultivating grass carp sustainably and ensuring optimal animal welfare.
