In Nile tilapia (Oreochromis niloticus) farming as in all fed aquacultured species feed accounts for 60 percent of the total production costs. Increasing prices of raw materials has led nutritionists to search for alternative ingredients to reduce or at least …

Aquaculture diet has become increasingly plant based. In addition, the industry faces environmental changes. Recent findings in salmonids show the two challenges are combined, give cause for concern.

Chronic Inflammation is a symptom of virtually every disease. Inflammation plays a major role in the development of the well known chronic problems of heart disease, cancer, diabetes, arthritis, eye disease, mood disorders, fibromyalgia and the list goes on an…

This paper by D. Allen Davis, Elkin Amaya, Jesus Venero, Oscar Zelaya and David B. Rouse, Auburn University, discusses from a historical perspective the systematic improvements in feed management that have allowed us to improve feed utilization and total produ…

Global seaweed production has more than doubled between 2000 and 2014, from 10.5 to28.4 million tonnes. The 2012 world production of seaweeds was estimated to be about US$6billion (FAO, Food and Agriculture Organization, 2014); 95% of this production was from …

Nutritional value of food and feed is just not declining, it is collapsing, write Dr. C. S. Bedi and Dr. R. Karthik, Aquaculture Division, Guybro Chemicals.

Although cleaner fish are proving an effective and environmentally friendly way of removing sea lice on salmon farms, they can carry pathogens that can cause disease in both the cleaner fish and salmon. Speaking at Aquaculture Europe, 20-23 September, Edinburg…

Mycotoxins, secondary metabolites produced by molds, can harm many varieties of aquaculturespecies. Here are 8 key facts about mycotoxins that reveal the real dangers for production.

The aim of this study by Tatiana S Barbosa, Universidade Federal Rural do Rio de Janeiro, et al was to determine species of the fungal genera Aspergillus, Fusarium, and Penicillium and fumonisin B1 (FB1), aflatoxin B1(AFB1), and ochratoxin A (OTA) contaminatio…

A new study by Future of Fish has explored the power of story to sell more fishand to determine what elements of that story most influence consumer purchasingbehavior. The study also aims to identify the business benefitsof data-rich supply chains and to ignit…

Dr Bill McGraw, an Aquaculture and Environmental Scientist in Panama, provides an overview of minerals in aquaculture and human diets.

In aquaculture, feed is amongst the most important factors that can impact fish growth rates. Most commonly found in pellet form, feed must be able to provide all of the required nutrients, offer the highest possible conversion rates, and of course be economic…

Over the past decade, the sustainability of seafood production has improved and is cause for ocean optimism. In an attempt for recognition of ongoing efforts, many producers and food retailers now claim products are sustainable, write Michael F Tlusty andistei…

Hammermills are commonly used for grinding a broad range of materials used in the production of aquaculture feeds. Since most species of fish, crustaceans, and shellfish have a very short digestive tract, they require a finely ground, highly processed feed in …

The rights of indigenous peoples living in coastal States to engage in their traditional fishing practices is an ongoing issue around the world. The central question lies in whether or not indigenous people are entitled to a preferred position, excluding or li…

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.

Given limited funds for research and widespread degradation of ecosystems, environmental scientists should geographically target their studies where they will be most effective. However, in academic areas such as conservation and natural resource management th…

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 Gonalves, Technical Prod…

There has been significant interest in the development of integrated multi-trophicaquaculture (IMTA) in Europe but adoption of the concept has been limited. If we are to understand why there has been limited uptake of IMTA in Europe, perhaps it is necessary to…

Christopher Golden and colleagues calculate that declining numbers of marine fish will spell more malnutrition in many developing nations.

A new remotely operated vehicle, or ROV, has been unveiled that could help reduce costs and improve operational efficiency and yields in aquaculture. Canadian firm Deep Trekker, which manufactures the DTG2 ROV, describes it as affordable, easy to use and capab…

This report by the FAO documents successful practices of the sustainable intensification of aquaculture in the Asia-Pacific region.

As seen in other animal species, fish individuals tend to react differently to a new situation. In the case of human harvest, the boldest individuals are more likely to get caught, leaving only the fearful and cautious ones to breed. But does it mean that futu…

Jesse T. Trushenski and Jonah M. May, Center for Fisheries, Aquaculture, and Aquatic Sciences, Southern Illinois University, evaluated the growth performance and fillet fatty acid composition of Hybrid Striped Bass that were fed diets containing principally ma…

World spiny lobster fisheries total 70,000 metric tons, with most coming from the countries of Australia, Brazil, the Bahamas, Cuba, Nicaragua and the US. The prominent species is Panulirus argus found throughout the Caribbean, which makes up half of the total…

Salmon farming companies have been switching their focus to the production of much larger smolt as a strategy for reducing netpen grow-out time and for reducing problems with sealice. Since recirculating aquaculture systems, with their warmer year round operat…

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 Manager.
