Tropical, subtropical marine fish hatchery technology needs improvement
Hatchery technology for most commercially important species of cultured marine fishes is essentially unchanged for the past several decades.
Natural strategies to improve growth and health of farmed shrimp
The application of probiotics, prebiotics and lipopolysaccharides has shown positive results with farmed shrimp, and is a very promising field, but more research is needed to clarify and foresee the molecular impact of these biological entities.
Prebiotics and their role in sustainable aquaculture
Results of a study to evaluate a commercial prebiotic on growth of European sea bass juveniles indicates this product can improve fish growth performance and allowing for the fish to reach the marketable size earlier, boosting their immune status, and reducing potential fish losses due to pathogens.
On the Job: Young fish veterinarian holds a hopeful outlook
Harry Hamlin-Wright is a fish vet. It’s a career choice that gets strange looks but offers him varied and interesting work. See the world of aquatic animal health and welfare through a fresh set of eyes in a new Advocate series on aquaculture jobs.
Animal health giants have sea lice in their crosshairs
Alltech and Benchmark have been working on the next generation of sea lice solutions and believe they have new products that can help salmon farmers win.
Potential applications of bacteriophages for AHPND control
Study demonstrates that isolated phages tested are effective in controlling AHPND infection in farmed penaeid shrimp and inhibiting bacterial growth.
Biofloc technology holds potential for carnivorous fish species
Juvenile carnivorous African catfish performed well in biofloc-based systems, which could help produce better quality and more disease-resistant seed of this important aquaculture species and support the expansion of African catfish farming industry.
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.
The history and future of the Aquaculture Pathology Laboratory
The University of Arizona’s Aquaculture Pathology Laboratory has significantly contributed to the expansion of the shrimp farming for three decades.
Asepsis key to prevent contamination in shrimp hatcheries
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.
Vacuna oral a base de gránulos o pellets es prometedora para la protección contra VNN
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.
A comprehensive look at the Proficiency Test for farmed shrimp
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.
Pellet-based oral vaccine holds promise for VNN protection
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.
Determining causes of osmotic stress in Pacific white shrimp postlarvae
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.
Evaluating effects of organic acids in Nile tilapia feed
A study tested the effects of a commercial product that includes three organic acids incorporated into a commercial feed for Nile tilapia fingerlings.
GOAL 2017 video: Fanny Giudicelli, Marine Akwa
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.
