Sea Hares (Dolabella auricularia) may not be familiar to anyone except a handful of medical researchers and marine aquarium enthusiasts. They get their name from the two rabbit ear like tentacles, known as rhinophores, on the top of their head that are used fo…

Aquaculture is one of the fastest growing food-production sectors but the economic impact that parasites and bacterial, fungal and viral diseases have on the industry is highly significant for the many countries that rely heavily on this industry. Research int…

This article focuses on approaches to improve ammonia and carbon dioxide utilization in algal cultivation practices to reduce loss of valuable nutrients through the process of volatilization

One third of all marine species that live in the sea spend at least part of their lives on coral reefs which are some of the most diverse ecosystems in the world, second only to rainforests. Slow growing coral reefs are worth more than the $billions in revenue…

DNA vaccines encoding viral glycoproteins have been very successful for induction of protective immunity against diseases caused by rhabdoviruses in cultured fish species. However, the vaccine concept is based on a single viral gene and since RNA viruses are k…

Two studies conducted at the University of Arizona showed that shrimp fed Calibrin-Z had survivability of 84% when challenged to induce Early MortalitySyndrome (EMS) vs. 5% for challenged shrimp not fed the enterosorbent, write Ron Cravens, DVM, Fang Chi and S…

Aquaculture is the fastest growing industry producing animal protein, with an average annual growth rate of 10 percent during the 1980s and 1990s. For the decade 20122022, aquaculture is forecasted to grow between 29 and 50% (FAO 2014).
