Fish feed and nutrition
Welcome to the page about Fish feed and nutrition of Engormix; a source of knowledge on Fish feed and nutrition.
The feed additives have the major role to improve feed efficiency and more important to make low Feed Conversion Ratio (FCR) in aquaculture production. Feed additives may be both nutritive and non-nutritive ingredients and work by either direct or indirect methods on the aquatic animal’s system. The feed additives are supplemented in small amounts (alone or in combination) for a specific purpose to improve the quality of shrimp as a final product. Also, it preserves the physical and...

Introduction Creatine (essential for energy metabolism) and glutathione (GSH; an important non-enzymatic antioxidant) are major metabolites of glycine [the simplest amino acid (AA)] in animals (Fig. 1). Specifically, arginine:glycine amidinotransferase (AGAT) and guanidinoacetate N-methyltransferase (GAMT) convert glycine into creatine in the presence of arginine and methionine, whereas γ-glutamylcysteine synthetase and glutathione synthetase catalyze the formation of GSH...

Abstract Raw industrial fish caught in SE-Asia for fishmeal processing decays quickly under tropical climate conditions and leads to lower protein quality. Therefore, it often needs to be supplemented with expensive fishmeal imports by the local feed industry. The effectiveness of potassium diformate (Fishform Plus®, KDF) as a preservative for industrial fish had been tested during a two-week onboard application in...

The rendering industry’s contributions to animal agriculture’s economic and environmental sustainability is vital, yet often overlooked when food and animal food production is discussed. The International Rendering Symposium, held in conjunction with the 2024 International Production & Processing Expo (IPPE) in Atlanta, will discuss rendering's contributions, impact and the future of the industry. Hosted by the North American Renderers Association (NARA) and U.S. Poultry...

Over the past twenty years, much success has been realized in the efforts to reduce the amount of fish meal in aquafeeeds in favor of other feedstuffs. Demand of fish meal as a principal source of protein has decreased due to many successful achievements, but is poised to increase as attention is being directed to the farming of more carnivorous species. A variety of approaches to achieve total substitution or reduction exist and are influenced by feeding habits...

Introduction The feeds for fish can be categorized as floating feeds, slowly sinking feeds, and sinking feeds. Each of these types of feeds are either made by exploring different types and amounts of ingredients, for instance, by controlling starch levels in the feed formulations or by varying the processing parameters, for instance, by modifying the screw profile, changing the screw speed, etc. Floating feeds are mainly made using an extrusion process whereas sinking feeds are...

Hi, I have a problem with the bulk density of the aquafeed. Recently we take some changes in our production process to increase the quality of the aquafeed. We put steam and water at 80 °C in the pre conditioner, and a 0.5/1.5 of oil. We add 23% of water and 7% of steam We reduce the speed of shaft to increase the retention time. We take also another die with higher open area to have less pressure to the die. The outgoing pellet from the extruder sink, but in the final product we have...

Pond production of intensively farmed white-leg shrimps, Litopenaeus vannamei (Boone, 1931), exceeded 2 million t in Central America and Southeast Asia in 2007, achieved through high-quality shrimp-feed supply in modern aquaculture. Despite progress in shrimp nutrition and new feed formulation strategies in recent years, disease outbreaks caused by pathogenic bacteria in shrimp ponds often result in significantly increased mortalities. Recent research in...

Introduction Animal production relies on the supply of nutritious feeds supporting high growth, welfare and health of animals and the production of high-quality products in an environmentally sustainable and profitable manner. With feed cost representing 50 to 80% of the total production cost, feed manufacturers have a very important role in the overall economic viability of animal agriculture enterprises. Animal production involves a complex “nutritional supply...

Introduction Early fish development is the most important thing that should be known before producing any seeds, especially in the new cultured species or strain. Generally, early development is divided into egg, larvae and juvenile, whereas mostly fish embryos develop from transparent eggs [1] . According to Kendall et al. [2], the egg stage is divided into early, middle and late subdivisions, which end with blastopore closure, freeing of the tail bud from the yolk, and...

In commercialization and high stocking density of culture practice, the feeding has the significant contribution for fast growth and high yields. The aquafeed is potentiated with many ingredients in highly balanced nutritious components for enhancing the digestive mechanisms in fish and shrimp body. It leads the better body weights, high health, optimum immunity, more survivals, less incidence of disease etc in aquaculture ponds. Spirulina is a unique high...
