INTRODUCTION Aquaculture is the fastest growing sector of food animal production in the world and supplies an increasing percentage of the total production of fish for human consumption ( FAO, 2012 ). Nowadays, Egyptian fish production from aquaculture contributed by 80% of total fish production which amounted 1.8 million metric tons ( Abdelhamid, 2019a ). Tilapia in different countries is farmed with fertilization and/or supplementary feeding. Feed is the highest...

Introduction The omnivorous Nile tilapia ( Oreochromis niloticus ) is an important commercially farmed species worldwide due to characteristics such as strong disease resistance, fast growth and the ability to accept lower cost diets with terrestrial-based ingredients ( Ng and Romano, 2013 ). Fish production costs are increasing while fish price in the market is relatively stable ( Tacon and Metian, 2015 ). Increased price of fish feed is one of...

1. Introduction Teleosts fish species are one of the largest sources of protein for humans through their extensive production in aquaculture. There has been a growing trend in the last decades into the use of genomics to improve our disease control and prevention strategies against various diseases infecting different fish species in aquaculture. As such, genomics studies in aquaculture have evolved from reductionist single gene sequencing to high throughput next (HTS)...

Background Infectious pancreatic necrosis virus (IPNV) is the causative agent of a contagious fish disease by the same name and is responsible for economic losses in the aquaculture industry worldwide. In 2015, this viral agent represented about 30% of disease diagnoses reported from Chilean salmon farming centers and caused about 8% of pathogen-associated mortalities [1]. Infections with IPNV mainly occur in the freshwater or fry first-feeding stages, but fingerlings of most...

Unprecedented demand for a slew of seafood products is likely to boost the U.S. crustacean market size as aquaculture seafood products continue to gain momentum in the region. Trend for commercial seafood products among millennial and gen Z population at various outlets will become more noticeable in the U.S. The commercial landings at ports by U.S. fishermen were pegged at close to 10 billion pounds (9.9 bn), valued at $5.4 bn in 2017.
Crustaceans have been gaining traction in...

Introduction. Organic selenium (OSe) has an advantage in reducing oxidative stress in comparison to inorganic forms and incorporates into skeletal muscles, kidney, liver, and gastrointestinal mucosa proteins as selenomethionine and selenocysteine. It is an essential micronutrient for fish (Martinez-Alvarez et al., 2005). Yeast cell wall has been proven as an immunostimulant and health improver for fish and other animals (Selim & Reda, 2015). Materials...
