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.

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…

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 …

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.

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

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

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…

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…

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.

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…

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.

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.…

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

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.

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…

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.

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…

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…

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

Scientists looking at the fecal material of 12 Baleen whales of three different species found some surprises. While Baleen whales are carnivores, feeding on fish and crustaceans, the microbes found in their guts the so-called whale microbiome share characteris…

This article offers an introduction to the new environmentally friendly and highly productive closed fish farming systems, by Jacob Bregnballe, FAO.

Aquaculture certification programs essentially mark milestones on the journey toward more sustainable practices. There is a role for a clearly defined starting point of minimum acceptable standards, but it is equally important to create incentive structures to…

The aim of this guide from the Irish Sea Fisheries Board (BIM) is to provide practical and contemporary guidelines on the handling and quality of herring, at all stages, from capture to the first point of sale.

IRTA researcher Enric Gisbert explains what the Feed Conversion Ratio is, how to calculate it and its importance for fish production.

Poxviruses are large DNA viruses of vertebrates and insects causing disease in many animal species, including reptiles, birds, and mammals. Although poxvirus-like particles were detected in diseased farmed koi carp, ayu and Atlantic salmon, their genetic relat…

For lovers of sushi, or those living in Asia, the sight of algae in a meal is not uncommon. Humans around the globe have consumed wild algae for centuries, but it is in Japan that the first farming of algae is believed to have begun.

Since the worlds first government-sponsored ecolabel The Blue Angel (Der Blaue Engel) was launched in Germany in 1978, ecolabels have become increasingly more commonplace.

Obligate and opportunistic parasites play a critical role in determining the productivity, sustainability and economic viability of global finfish aquaculture enterprises. Without stringent and appropriate control measures, the impact of these pathogens can of…

Consumer awareness of sustainable aquaculture production has led to increased interest in certification for sustainable aquaculture practices. In contrast to common belief, this certification encompasses a broader scope than just environmental issues. It also …

The aim of this guide from the Irish Sea Fisheries Board (BIM) is to provide practical and contemporary guidelines on the handling and quality of Blue Whiting, at all stages, from capture to the first point of sale.

A new technology promises to revolutionize the simultaneous detection of mycotoxins and greatly expand our scientific knowledge. Several cases in the field along with the 2014 BIOMIN Mycotoxin Survey results reveal the value of multiple mycotoxin detection in …

Dr Bob Carling writes about the influential ideas of economist Nicholas Stern on the value that we place on biodiversity.

This article is the second in a two-part series about Japan's Kinki University Fisheries Laboratory. The first article looked at the history of the facility and how tuna is being farmed. This article focuses on the challenges the Laboratory faces, and some fut…
