The striped spiny eel, Macrognathus pancalus, is economically significant but faces population decline due to anthropogenic factors. This study presents a comprehensive approach to breeding and seed production techniques for M. pancalus, conducted at the Regional Research Centre, ICAR-Central Institute of Freshwater Aquaculture, Rahara, India. The study describes broodstock management simulation of natural habitat to stimulate natural breeding. Techniques for hatching and larval rearing, management of early spawn, and precautions to prevent cannibalism are presented. Survival of 88% after one month was achieved. The breeding and seed production techniques provided are suitable for farmers to adapt, and will contribute to the conservation and utilisation of M. pancalus in sustainable aquaculture practices. The findings also highlight the economic potential of this species to provide a nutritious option for consumers at affordable prices.

This study explores the cultivation of the Indian spiny loach, Lepidocephalichthys thermalis, in indigenously designed poly-lined iron frame tanks as a sustainable solution. The article details the fabrication methods for these tanks, highlighting the use of rust-resistant iron and low-density polyethylene sheets.The study proposes a supplementary feed mixture and provides insights into water quality management to ensure optimal conditions. The study demonstrates the potential for achieving a net production level of 1 kg from 400 liters, offering economic viability for farmers. The modified tank-based rearing system is shown to be beneficial in hilly regions with limited land and water resources.

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 4^th quarter of 2020), NACA is publishing reported aquatic animal diseases submitted by countries in the Asia-Pacific region. This report covers the third quarter of 2023 and the original and updated reports can be accessed from the QAAD page. 

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.
