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.

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, Pikul …

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, su…

Fishing doesnt 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 contaminatio…

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 Torres,…

This animal has done everything right. It has been around for 300 million years, outlived the dinosaurs and survived the catastrophic meteorite impact, warm phases and glacial periods.Even today, it continues to populate the sea at depths where it eats carrion…

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, writes…

This guide explains how integrated aquaculture farming (where a farmer can rear fish, chicken and plant vegetables) on a plot of 10 by 10 feet can generate food and an income for a family in the Philippines.

A major European-wide research project is making strong inroads into developing new breeding programmes to improve the stock of six important aquaculture species, writes Chris Harris.

Shrimp culture tends to now be developed intensively with upgraded technology for higher and successful production.In many occasions shrimp culture are affected by various diseases and experienced in loss of crop or reduced the production level by various reas…

This study was carried out to evaluate the value chain performance of the aquaculture feed sector in Egypt, in terms of value addition, employment and profitability, write Abdel-Fattah M. El-Sayeda, Malcolm W. Dicksonb and Gamal O. El-Naggarb, Alexandria Unive…

Fishing incurs costs from many different aspects the vessel itself, fuel, fishing equipment, crew, licences, and so forth. Making sure every bit of a catch counts as income is essential especially where fishers are running on tight margins.

An Aquaculture Experience Farm in Java operates a hybrid system, based on a careful balance between autotrophic and heterotrophic organisms which gave average outputs of 20 tonnes/ha in early 2013, Agus Saiful Huda, Junaedi Ispinanto, Fauzan Bahri and Olivier …

The threat of disease in the aquaculture industry, coupled with greater restrictions or ban on antibiotic use, has increased interest in evaluating antibiotic alternatives, write Wing-Keong Ng et al, Universiti Sains Malaysia.

Salmon migrating from the open ocean to inland waters do more than swim upstream. To navigate the murkier freshwater streams and reach a spot to spawn, the fish have evolved a means to enhance their ability to see infrared light. Humans lack this evolutionary …

Often dubbed the aquatic chicken, farmed tilapia is now a staple in many parts of the world. A healthy source of protein, micronutrients and essential fatty acids, tilapia is now the fourth most consumed fish in the US and it is farmed extensively in China, Eg…

Researchers from the Queensland Brain Institute at The University of Queensland have uncovered a new form of secret light communication used by marine animals.

The recent boom in 3-D printing has driven innovations in fields as disparate as haute couture and medical implants.

This article shows the retention efficiency of nutrients from feed resources to final product in Norwegian salmon production, including limiting resources such as the omega-3 fatty acids EPA and DHA and phosphorous. It is highly relevant to compare the efficie…

Scientists have solved a longstanding mystery about how some fish seem to disappear from predators in the open waters of the ocean, a discovery that could help materials scientists and military technologists create more effective methods of ocean camouflage.

Cultured marine fish larvae are most often fed rotifers (Brachionus sp.) the first few weeks after first-feeding. However the nutritional value of rotifers is generally inferior to the natural diet of marine fish larvae which is comprised of zooplankton, mostl…

Extracellular Polymeric Substances (EPS),1 or exopolymers, play vital roles in the productivity of commercial hatcheries, yet have received little attention in aquaculture outside of their role in the biofilters of recirculating systems, write A. Joycea and S.…

The main objective of this study by Hooi Ling Khaw et al, Wageningen University, Netherlands, is to quantify the genetic and non-genetic indirect effects for harvest weight in the GIFT strain of Nile tilapia.

In early 2014, a trial to evaluate the effects of a mixture of Bacillus strains on early mortality syndrome bacteria during the larviculture and nursery phases for shrimp was carried out at a commercial hatchery in Mexico, write Oliver Decamp et al, INVE Aquac…

Research by Anna K. Farmery et al, University of Tasmania, Australia, has found that the distance seafood is transported is not the main determinant of food sustainability. Despite the increased distance between production and consumption, carbon footprints of…

Research by Phuthongphan Rattayaporn, Srianek Patipon, Roeland Wouters, Geert Rombaut and Olivier Decamp, INVE Aquaculture, discovered increased palatability of shrimp feed when it was coated with a specific probiotic.

This article will show different behaviours of oxidative disinfectants in corrosivity and efficacy under soiled conditions.

On hot, humid days, you might jump into water to cool down, but for the tiny mangrove rivulus fish, cooling down means jumping out of water, according to a new study from the University of Guelph.

Sub-Saharan Africa presents a solid marketing opportunity for tilapia producers, processers and traders, particularly in view of the dwindling nature of traditional sources of fish, population growth, and rising incomes. However, it is important to first under…

This article by Dr Abdel Raheam H. A. El-Bassir and colleagues from Sudan explores the effects of preserving fish using salt on its nutritional properties.

Achieving better growth rates or improved efficiency relies on good gut performance in aquaculture species, write Rui Gonalves, Gonalo Santos..

When it comes to catching elusive prey, many fishes rely on a special trick: protruding jaws that quickly extend their reach to snap up that next meal. Now, researchers reporting in the Cell Press journal Current Biology on October 8 have found a clever way to…
