Fish feed and nutrition
Welcome to the page about Fish feed and nutrition of Engormix; a source of knowledge on Fish feed and nutrition.
Introduction Feed management is a key factor affecting water quality (Boyd and Tucker 1998, Jory 1995) and production economics in aquaculture (Jolly and Clonts 1993). Not only is the feed the initial 0source of physiological wastes, but it accounts for 55% to 60% of the operation costs in intensive systems and around 40% in semi-intensive systems (Chanratchakool et al. 1994,...

INTRODUCTION During the last three decades, a great attention was paid towards aquaculture as an attempt to fulfill the gap between the increased population and their demands from animal protein. Aquaculture is still the fastest growing food producing sector, compared to other food commodities with an annual increase of approximately 12% ( FAO, 2009 ). The use of antibiotics in aquaculture as...

During the past 20 years, the pond culture of hybrid striped bass has developed into a successful sector of the United States aquaculture industry; annual production has grown exponentially from 10,000 pounds to nearly 12,000,000 pounds during that period. A three-phase production system has been used. Phase I (nursery phase) consists of producing 30- to 45-day-old fingerlings in fertilized “fry” ponds (SRAC Publication #302). In Phase II, these...

Introduction Between 1.5 and 2 million households worldwide are believed to keep tropical marine aquaria and the collection trade which supplies this industry is estimated at US$220-330 million annually (Wabnitz et al., 2003). The majority of these imports are destined for the United States, Europe, and Japan (Chapman et al., 1997). Unlike freshwater aquaria species, where 90% of fish species are farmed, only 100 of the...

Background Aquatic products represent an important food source for animal and human consumption, the rising demand of which had led to a fast development of aquaculture (Myhr and Dalmo 2005). The primary objective in fish nutrition is to provide a nutritionally balanced mixture of ingredients as finished feed to support the maintenance, growth, reproductive performance, flesh quality, and health of the animals at an...

The Spanish Company, Liptosa , has started a new CDTI project called LIPTOAVAN , which main objective is the development of phytobiotics and nutraceuticals able to face common aquaculture pathologies.
The project, which was approved in may this year, supports the use of phytobiotics “as animal welfare enhancers and sustainable aquaculture”.
To develop the project a new research line will be applied focused on the identification of...

Feeding is the most important task in the intensive pond production of catfish, and the person responsible for feeding should be an experienced fish culturist. In a normal situation, catfish can be seen only when they are coming up to feed, and their feeding behavior can be an important clue to general health and to other conditions in the pond. Thus, the person doing the feeding must be able to tell whether or not the fish are feeding normally. If they are not, the feeder must inform the...

INTRODUCTION Fish as a source of animal protein has played an important role in the nutritional budgeting of many nations. Fish production is becoming a very important source of valuable protein food. Fishmeal is the major protein source in aquaculture feeds. However, the supply of fishmeal is not growing worldwide and the price is often high, so the replacement of fishmeal with cheaper protein sources is needed. Chicken...

Introduction Good nutrition in aquaculture systems is essential to economically produce a healthy and high quality product. Vitamins are essential nutrients found in foods. They perform specific and vital functions in a variety of body systems and these are crucial for maintaining optimal health. Vitamins are a heterogeneous group of organic compounds essential for the growth and maintenance of aquatic animal life....

The ongoing outbreak of early mortality syndrome/acute hepatopancreatic necrosis (EMS/AHPN) has had dramatic impacts on shrimp producers in affected countries in Asia and Mexico. Following reports of the disease being associated with broodstock management – for example, through the use of contaminated polychaetes – there has been a renewed focus on larval quality. Investing in quality larvae fits well in the holistic...

ABSTRACT The present study was performed to investigate the effect of feeding different levels of poultry by-product meal as untraditional ration constituents on fish performance, and apparent digestion coefficients. A total number of 90 apparent healthy Nile tilapia fingerlings were randomly distributed into 5 groups, each of 18. The first group was considered as a control (T1) and was fed...

The concept of functional aquafeeds represents an emerging new paradigm to develop diets for fish and crustaceans. Functional feeds extend beyond the satisfying basic nutritional requirements of the cultured organism to improve growth and feed utilisation also the support of general health and stress resistance of the animals. The increasing concerns about residues of antibiotic or anabolic agents in food production lead to a restrictive use of these substances...

INTRODUCTION Most of the Egyptian wild (marine, brackish, and fresh) water bodies is contaminated with agricultural, industrial, and urban drainage, which is responsible for their water and fish pollution with different heavy metals (Abdelhamid et al ., 2006a and 2013 a&b) at levels exceeding the Egyptians’ tolerance limits (ES, 1993 and Abdelhakeem et al.,...

Introduction
Although antibiotic growth promoters in the diets of fish may promote growth and improve feed conversion and survival rates, public concern over cross-resistance to humans led to a ban on the use of such substances in the EU. Research has thus turned to other feed additives to maintain performance and high survival rates in aquaculture. Organic acids and their salts are seen as an alternative to...
