Rising Sea Water Temperatures Causing Coral Bleaching in Seca Islands, Panama
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...
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...
Functional Feed Additives for a Sustainable Blue Revolution
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 2012–2022, aquaculture is forecasted to grow between 29 and 50% (FAO 2014). ...
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 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,...
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...
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...
Avoiding the Choke
The European Union’s Common Fisheries Policy has undergone many reforms since its creation. Last year saw the introduction of first phases of one of the most significant reforms – the Landing Obligation. Under this new rule (with a few exceptions)...
Patenting Genetic Material in Aquaculture: A Red Herring or an Emerging Issue to Tackle?
Aquaculture farmers and breeders need legal certainty about how the increasing number of patents over aquatic genetic material can affect their breeding programs, writes Fran Humphries, Griffith University, Australia....
The Problem of Overfishing: Can Japan's Attempts to Lower Catch Limits Provide a Solution?
Japan has decided to tighten its rules on overfishing this year. With fishery resources around the country at increasing risk of being depleted, Bonnie Waycott reports for The Fish Site on Japan's attempts to address an increasingly serious global problem....
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....
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,...
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,...
Top Tips for Preventing Fish Spoilage During Handlling
Fishing doesn’t just end with capturing the fish. Once the fish is sorted and stored on the boat, it is then taken back to shore where it is either processed, or sold directly. This is a crucial step – improper handling of seafood can result in their...
