14th Asian fisheries and Aquaculture Forum: Early bird closes 10 November

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

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

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.
