Genetic improvement of disease resistance through selective breeding
This study, involving more than 10 years of research on selective breeding, has shown that selective breeding can create considerable phenotypic divergence in rainbow trout lines when targeting a specific pathogen.

Organic acids in aquafeeds: A potential substitute for antibiotics
Prophylactic use of antibiotics in animal production is being banned or restricted by many countries. A potential substitute for antibiotic growth promoters in aquafeeds is organic acids, which are the focus of much research and commercial interest.

Selection for disease resistance in Indian white shrimp
A new breeding program for genetic improvement of Indian white shrimp (Fenneropenaeus indicus) in Egypt was established at a private shrimp farm at AL Dibah Triangle Zone (DTZ) to develop disease-resistant shrimp for the country’s aquaculture industry.
