Beneficial Microbes for the Sustainable Management of Shrimp Aquaculture
Aquaculture production has grown enormously in recent years and among that Penaeid shrimps are one of the most important cultured species worldwide especially in Asia due to their high economic value and export....
Nutrient Sparing: A Sustainable Tool for Long-Term Profitability
Aquaculture production can address contradictory challenges such as costs and environmental footprint by using phytogenic feed additives that improve digestibility, nutrient retention, feed efficiency and reduce emissions, write By Rui Gonçalves, Technical...
The Role of Nutrition in Gut Health
Nutrition along with environment and host physiology comprise the three main factors for strong gut performance. This second article in our gut health series reveals how nutrition can influence gut health, writes Otavio Serino Castro, Technical Sales...
Nutraceutics for the Control of Bacterial Coldwater Disease
The aquaculture industry has developed significantly over recent decades and is, today, one of the fastest-growing food production sectors in the world. One of the most important problems that affect aquaculture is the appearance of infectious diseases....
The Challenge of Shrimp Diseases in Asia
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...
Can VHS Virus Bypass the Protective Immunity Induced by DNA Vaccination in Rainbow Trout?
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...
Calibrin® -Z Increases Shrimp Survival During Early Mortality Syndrome (EMS) Challenge
Two studies conducted at the University of Arizona showed that shrimp fed Calibrin-Z had survivability of 84% when challenged to induce Early Mortality Syndrome (EMS) vs. 5% for challenged shrimp not fed the enterosorbent, write Ron Cravens, DVM, Fang...
Effects of Fish Meal Substitution with Poultry By-product Meal on Juvenile Nile Tilapia
AMM. Yones and AA. Metwalli from the National Institute of Oceanography and Fisheries, Shakshouk Fish Research Station, El-Fayoum, Egypt, look at the effects of fish meal substitution with poultry by-product meal on the growth performance, nutrients utilization...
Effect of a Functional Feed Additive on Productivity in Ecuadorian Shrimp Farming: a Pilot Scale Demonstration
Maintaining a stable and favorable gut microflora is of crucial importance to minimize the impact of disease events and to optimize digestive efficiency in shrimp, resulting in improved survival and productivity. The present paper illustrates the potential...
Effect of Dietary Salt Supplementation on Growth, Survival and Feed Utilization of Tilapia
Malawi’s fish production is dwindling and the development is not in tandem with the human population increase. In view of this, it is imperative to increase fish production to tally with the high market demand, write Mzengereza K, and Kang’ombe J,...
Multiple Benefits from Promoting Gut Health in Aquaculture
The European ban on the use of antibiotic growth promoters in livestock, and the subsequent search for alternatives, has revealed the importance of gut health and the development of a stable, favorable gut microflora, on feed efficiency, overall performance...
Low Temperature Performance of Disinfectants
Many disinfectants, which claim proper efficacy against many pathogens, are often tested at ideal circumstances, meaning room temperature (25 degrees C), clean surfaces with no dirt and mostly against one single type of microbe....
Counting the Cost of Aquatic Disease in Asia
The true cost of each disease outbreak is complicated by an intricate interplay of environmental and management-based factors, from the direct losses in stock, through to indirect losses in the downstream industry, writes Andy Shinn, Jarunan Pratoomyot,...
Resistance to Kudoa thyrsites in Atlantic Salmon
Research by Simon R.M. Jones,Steven Cho, Jimmy Nguyen and Amelia Mahony from the Canadian Pacific Biological Station, has found that Atlantic salmon which have recovered from infection with Kudoa thyrsites showed resistance to reinfection with the parasite,...
Microbial Dynamics in Shrimp Ponds
Understanding the microbial ecological process in ponds and in the shrimp intestinal tract is vital to maintain and optimize productivity without prophylactic use of hazardous substances, write Marcos H. S. Santos, Tadeu de Silva (INVE do Brasil), Jose...
