Title : Plant protein-based alternatives in aqua-feeds: Advantages, challenges and solutions
Abstract:
The current talk will evaluate the use of innovative plant products in aqua-feeds to promote the sustainable production of multiple fish species in aquaculture. The development of sustainable protein sources to substitute fishmeal (FM) in aqua-feeds is critical to the continued growth and intensification of aquaculture productivity. Fish feed plays an important role in the growth of the aquaculture industry. FM has been employed as the principle protein element in aquaculture because of its beneficial essential amino acids, high digestibility, and palatability. FM prices are expected to rise by 20% between now and 2030 because of rising demand and increased output. This requires the search for better FM alternatives for long term aqua-feed production. In this light, much efforts have been conducted to seek the sustainable supplies of protein sources to substitute FM. Good nutrition in production systems is essential to economically produce a healthy and high product. The first consideration for formulation of feed is the quality of the feed ingredients. Use of plant protein source in the feed industry has been in practice for various advantages such as sustainability, availability, cost effectiveness etc. Because of their high protein content, excellent amino acid profile, low cost, and year-round availability, they are commonly utilized as a cost-effective alternative to high-quality fish meal in diets for many aquaculture fish species. Moringa oleifera leaf meal, Moringa oleifera seed meal, canola meal, sunflower meal, and cottonseed meal have all been studied extensively. Different supplements, such as enzymes, probiotics, organic acids, and nano-particles, are also given to fish meals in addition to plant by-products. All of these factors help fish species enhance their growth, nutrient digestibility and body composition.
Audience TakeAway Notes:
- Other researchers can use these innovations to expand their research.
- This study will help the audience in using plant protein sources as aquafeeds to improve overall fish production.
- This will provide a practical solution to formulate cost-effective, easily available, and environmentally friendly fish feed.
