The University of Arizona’s Aquaculture Pathology Laboratory has significantly contributed to the expansion of the shrimp farming for three decades. 

Maintaining biosecurity and asepsis in larval shrimp production is a key component of the production chain in Ecuador, which requires the production of 5.5 billion larvae monthly from 300-plus hatcheries.  

Una vacuna oral administrada a través de alimento para peces para defenderse contra la necrosis nerviosa viral podría estar lista para el mercado pronto si todo va según el plan para el arranque de VakSea. 

The University of Arizona Aquaculture Pathology Laboratory has carried out the Proficiency Test (PT) since 2005, with 300-plus diagnostic laboratories participating while improving their capabilities in the diagnosis of several shrimp pathogens. 

An oral vaccine delivered via fish feed to defend against Viral Nervous Necrosis could be ready for market soon if everything goes according to plan for startup VakSea. 

This study evaluated the relationship between the molting stage, age and osmotic stress in Pacific white shrimp postlarvae. The results indicate that osmotic stress tests should be done only with at least PL12 at the intermolt stage and that were cultured at 35 ppt salinity and 29 degrees-C. 

A study tested the effects of a commercial product that includes three organic acids incorporated into a commercial feed for Nile tilapia fingerlings. 

In the second Pecha Kucha presentation from the Global Aquaculture Alliance's annual GOAL conference in Dublin, Ireland, Fanny Giudicelli of Marine Akwa talks about how marine probiotics, derived from seaweed, can help the industry's efforts in combatting infectious diseases. 

A look at economic implications of predatory birds on commercial tilapia facilities, and the various control technologies – mostly non-lethal, such as frightening techniques – used by the industry to protect its farmed fish. 

At the Global Aquaculture Alliance's annual GOAL conference, held last month in Dublin, Ireland, we introduced a series of Pecha Kucha presentations about the future of aquaculture. We'll feature all seven on the Advocate, starting with Neil Manchester's rapid-fire view at how genetics are improving breeding techniques for aquaculture. 

Predatory birds can cause major losses for tilapia farms. As some bird species are protected by law, fish farmers must use non-lethal control techniques. 

The Scottish salmon industry is facing criticism following the release of sea lice statistics and acknowledgement that up to 10 million salmon – a quarter of all stocks – were thrown away last year as a result of disease, parasites and other issues. 

In this third and final part, authors present recommendations to help reduce the incidence of Zoea-2 Syndrome, which is not caused by any known infectious agents in P. vannamei hatcheries in India. 

Indian shrimp hatcheries have experienced larval mortality in the zoea-2 stage, with molt deterioration and resulting in heavy mortality. Authors considered biotic and abiotic factors. Part 2 describes results of their study. 

Indian shrimp hatcheries have experienced larval mortality in the zoea-2 stage, with molt deterioration and resulting in heavy mortality. Authors investigated the problem holistically.
