Better management practices for tilapia hatcheries in Egypt

Tilapia hatcheries are the most common type of fish hatchery in Egypt. They are nearly all private sector businesses, and their success in supplying fish farms with tilapia seed has contributed to the increase in national farmed fish production. There are three different hatchery systems used for Nile tilapia: (1) concrete tanks with a water-heating system, (2) hapas under plastic tunnels and (3) hapas in open ponds. The fish farming industry is growing quickly, and tilapia hatcheries have to improve the quality of seed production for fish farmers to maintain their profit margins.

11th Symposium on Diseases in Asian Aquaculture (DAA11)

A forum to explore the technical knowledge and experiences surrounding aquatic animal health.

Date: Monday-Thursday, 23-26 August 2021

*Stay tuned for the registration link for virtual audience*

The Diseases in Asian Aquaculture (DAA) series is held once in every three years and for 2021, the DAA11 symposium will bring together professionals, academicians, and field experts to discuss the core aspects of aquatic animal health.

Basic biosecurity manual for tilapia hatchery technicians in Bangladesh (Bangla version)

With the onset of Tilapia Lake Virus (TiLV) outbreaks in several Asian countries, WorldFish, in collaboration with Bangladesh’s Department of Fisheries, has developed a program to improve biosecurity in the tilapia industry throughout the country. As the first step, a training program has been designed and conducted to train a group of specialists called Master Trainers on improving tilapia hatchery biosecurity. This manual is a result of that program.

Vulnerabilities in aquatic animal production

The role of aquatic animals in global food and nutrition security is increasingly recognised. The global demand for fish is increasing, leading to a need to significantly increase its supply. Securing future fish supplies through sustainable production is a challenge as major resources such as fresh water and land are becoming limited worldwide. Aquaculture and capture fisheries face various threats from both human-mediated and natural environmental change, including climate change. Aquaculture systems and practices are vulnerable to such changes.

Impacts of epizootic ulcerative syndrome on subsistence fisheries and wildlife

Epizootic ulcerative syndrome (EUS), caused by the water mould (Oomycota) Aphanomyces invadans, has spread throughout the world’s major continents over the last 50 years, with the apparent exception of South and Central America. With over 160 susceptible fish species representing 54 families and 16 orders recorded to date, EUS is of international concern and infection with A. invadans is a World Organisation for Animal Health (OIE) listed disease.
