This short research note provides insights on the invasive apple snails (Pomacea spp.) and rice cultivation in Brunei Darussalam. This freshwater invasive snail was first detected in 2009, but it was never introduced intentionally. Since then their population has increased swiftly and spread to almost all the rice areas across the country, becoming a major pest of irrigated transplanted rice. Research and collaboration among infested countries is important for accurate species identification and better understanding of the invasion pathways.

NACA’s 29th Governing Council Meeting was held in the Maldives capital, Malé, from 26-27 June, with attendance by fifteen member governments. This was the first official NACA meeting in the Maldives, since it became a member in 2014, and also the first time that most of the delegates had visited the country, affording participants a fascinating glimpse of a very different lifestyle in the archipelago, and a very different development context.

Some varieties of freshwater fish have low growth potential but remain economically attractive due to market preferences. The endangered catfish Horabagrus brachysoma is one such fish, which has limited production but high market demand, and a number of favourable biological characteristics. This article provides guidelines for the culture of this catfish in captivity including for the breeding, nursery, stocking and growout, including advice on pre- and post-stocking practices, harvesting and health management.

The American Fisheries Society and the Environmental and Water Resources Institute of the American Society of Civil Engineers are holding this year's annual Fish Passage conference in Australia in December in collaboration with hosts Charles Sturt University and the New South Wales Government. The International Conference on River Connectivity, to be held in Albury from December 10 to 14 includes the First International Symposium on Hydropower and Fish Management.

Despite their abundance at one time in India and other Asian nations, wild mahseer populations have been declining because of degradation of aquatic ecosystems, urbanisation and indiscriminate fishing. Wild mahseer are populations are presently struggling for their mere existence.

An international workshop on mahseer conservation, propagation and rehabilitation will be held in Bhimtal, India from 23-24 April 2018. The workshop is organised by the ICAR-Directorate of Coldwater Fisheries Research in collaboration with the Coldwater Fisheries Society of India.

BRAQCON 2019 wil cover latest research and development in the broader themes of the conference in the form of special sessions, contributed papers, expert group discussions and brainstorming on issues facing aquaculturists and ecosystem managers in India and around the world. The conference themes include: Brackishwater ecosystems, estuarine biodiversity and conservation; aquaculture production systems; larviculture; fish and shellfish nutrition; environment and climate change; aquatic animal health; socio-economic and livelihood issues; and aquaculture genetics and biotechnology.

Originating from South America the apple snail species of Pomacea, commonly referred to as golden apple snail, was imported into Vietnam from 1985 to 1988 with the intention of raising it for human consumption. Not long after that, the introduced snails quickly spread to most freshwater ecosystems of the country. This review examines the current status and history of apple snail introduction in Vietnam, and the various control and management measures used to cope with snail infestations.
