“…Choices in the ingredient matrix will therefore influence the taurine level provided through practical ingredients, which in turn will influence the amount of purified taurine to be added, if necessary, in order to meet the requirement. This could explain the positive response of fishes to low-fishmeal feeds with supplemented attractants (Espe et al, 2007;Kader et al, 2012;Kolkovski et al, 2000;Suresh et al, 2011): indeed, often-used attractant products include fish solubles, krill meal and squid meal, which contain significant levels of taurine (Spitze et al, 2003).…”

Taurine: a critical nutrient for future fish feeds

Taurine is a sulfonic acid found in high concentrations in animal tissues. In recent years, a number of studies have demonstrated the essentiality of dietary taurine for many commercially relevant species, especially marine teleosts. Consequently, the removal of taurine-rich dietary ingredients such as fishmeal may create a deficiency, of which symptoms include reduced growth and survival, increased susceptibility to diseases, and impaired larval development. These symptoms emphasize the systemic role of taurine in the animal's physiology and provide few clues as to the underlying mechanisms of taurine function. In fact, a myriad of roles have been attributed to taurine in mammals, ranging from bile salt conjugation to membrane stabilization, osmoregulation, anti-oxidation, immunomodulation, calcium-signaling, and neuroprotection. This review describes the current knowledge of taurine physiology and metabolism in fish and requirement levels in relevant species, and highlights possible parallels with mammalian taurine metabolism. In addition, the effects of ingredient processing and feed manufacturing on taurine bioavailability are discussed. Finally, regulatory aspects are brought to the forefront: although the supplementation of taurine will be necessary to further reduce the use of ingredients such as fishmeal, taurine is not currently approved by the FDA in the USA for fish feeds.Obtaining approval in the United States to utilize taurine in fish feeds can improve the environmental and economic sustainability of fish feeds nation-wide.

“…It is possible that the reduction in feed intake observed with some of the test products was due to the ability of some zeolites to bind nitrogen compounds (Nguyen and Tanner 1998); shrimp respond well to the presence of attractant compounds to ensure feed intake (Suresh et al 2011).…”

“…Suppadit et al (2006) and Soonngam and Hutacharoen (2007) observed that adding HSCAS or vermiculite to aflatoxin-contaminated diets lessened the negative effects triggered by the mycotoxin in Fixat presentaron una disminución en su consumo de alimento (alrededor de 10-12%) y tasa de crecimiento (alrededor de 4-17%); en contraste, los individuos alimentados con NCD + Novasil Plus mostraron un mayor consumo de alimento (alrededor de 6%) y tasa de crecimiento (alrededor de 8%). Es posible que tal disminución del consumo de alimento se debió a la capacidad de algunas zeolitas de secuestrar compuestos de nitrógeno (Nguyen y Tanner 1998); los camarones responden bien a la presencia de compuestos atrayentes para asegurar su ingesta de alimento (Suresh et al 2011).…”

The safety and effectiveness of four aluminosilicate-based products (Novasil Plus, Zeolex Extra, Mycofix Select, and Fixat) were tested for 42 days on juvenile Pacific white shrimp, Litopenaeus vannamei, fed diets containing corn grains that had been previously inoculated with Aspergillus parasiticus and then sterilized. Two control diets, one uncontaminated and another contaminated with the contaminated corn grain, were elaborated to contain a final concentration of 0 and 75 μg kg–1 total aflatoxins. Both diets were formulated to contain 38% crude protein and 8% lipids. Eight more diets were manufactured from the previous two to contain each of the test products at inclusion levels of 2.5 to 5.0 g kg–1, in accordance with the inclusion level recommended by the manufacturer. Mycofix Select and Fixat inclusion improved diet stability (12–16%). Water absorption capacity in the diets increased (from 2% to 17%) due to the supplementation of aluminosilicates. Feeding aflatoxin-contaminated diets to Pacific white shrimp resulted in lower feed intake and weight gain without affecting the feed conversion ratio, nitrogen retention, and survival. Feeding the uncontaminated diets supplemented with Zeolex Extra, Mycofix Select, and Fixat resulted in a slight reduction in feed intake without affecting growth rate, nitrogen retention, or survival. Conversely, the inclusion of Novasil Plus in the uncontaminated diet did not affect feed intake and an 8% growth rate improval was observed. Three of the tested products failed to provide complete restoration of feed consumption and shrimp growth rate when added to the aflatoxin-contaminated diet.

“…This is not a surprise since fish meal is high in demand and thus, many researchers [116,117] have tried to substitute fish meal with alternative ingredients in their studies. The alternatives that could maintain the palatability of the shrimp feed such as krill meal [118,119] and poultry by product meal [120] have been tested. Many other combinations of ingredients could be obtained through this EA.…”

Shrimp Feed Formulation via Evolutionary Algorithm with Power Heuristics for Handling Constraints

et al. 2017

View full text Add to dashboard Cite

Formulating feed for shrimps represents a challenge to farmers and industry partners. Most previous studies selected from only a small number of ingredients due to cost pressures, even though hundreds of potential ingredients could be used in the shrimp feed mix. Even with a limited number of ingredients, the best combination of the most appropriate ingredients is still difficult to obtain due to various constraint requirements, such as nutrition value and cost. This paper proposes a new operator which we call Power Heuristics, as part of an Evolutionary Algorithm (EA), which acts as a constraint handling technique for the shrimp feed or diet formulation. The operator is able to choose and discard certain ingredients by utilising a specialized search mechanism. The aim is to achieve the most appropriate combination of ingredients. Power Heuristics are embedded in the EA at the early stage of a semirandom initialization procedure. The resulting combination of ingredients, after fulfilling all the necessary constraints, shows that this operator is useful in discarding inappropriate ingredients when a crucial constraint is violated.
