Status on development and use of alternative dietary ingredients in aquaculture feed formulations in Viet Nam
Abstract
This paper reviewed fish catch production and estimated demand of aquafeed, fish meal, fish oil, soybean meal in Viet Nam for year 2013. Fish catch production was around 2.8 million metric tons (mt) while marine fish production was 1.9 million mt. Estimated marine trash fish production was 0.8 million mt with over 100 species including the dominant species anchovy (Stolephorus spp.), lizard fish (Saurida spp.) and pony fish (Leistognathus spp.).
Approximately 0.5 million mt of marine trash fish was used for livestock, aquaculture and fish meal. Local marine fish meal consisting of protein content from 50 to 68% and catfish byproduct meal containing protein level from 50 to 60% were available. Based on FCR values of 5 major species including catfish, black tiger shrimp, white leg shrimp, Asian seabass, and snake head, aquafeed production was estimated at around 2.5 million mt. Marine fish oil/squid liver oil requirement was from 15.5 to 31 thousand mt. Fish meal demand was from 252 and 430 thousand mt. Almost all fish meal and marine fish oil used in aquafeed were imported.
Moreover, soybean and other plant ingredients are potential alternative sources to replace fish meal and fish oil. Vietnamese farmers produced 168 thousand mt soybean while soybean demand amounts for aquafeed were from 693 to 1,140 thousand mt. In 2013, feedmills imported approximately 3 million mt of soybean meal (cake) from many countries in the world. Some other plant protein sources which were also imported, have good nutrient profiles but they contain some anti-nutritional factors.
In the future, research on replacement of fish meal and fish oil with plant and animal by-product sources and feed additives for aquafeed should be studied. In particular, the management of local fish meal plants and capture fishery should be improved.

Development and use of alternative ingredients or fish meal substitutes in aquaculture feed formulation: Proceedings of the ASEAN Regional Technical Consultation on Development and Use of Alternative Dietary Ingredients or Fish Meal Substitutes in Aquaculture Feed Formulation
- 2015 - Aquaculture Department, Southeast Asian Fisheries Development CenterRecognizing the need for a concerted effort to follow-up on this priority issue of the ASEAN on aquaculture feed development and utilization. SEAFDEC (Aquaculture Department and Secretariat) and the Government of Myanmar organized the 'Regional Technical Consultation (RTC) on development and Use of Alternative Dietary Ingredients or Fish Meal Substitutes in Aquaculture Feed Formulation'. The meeting was convened with the main purpose of providing a forum for charting the regional priorities and future directions on feed development, particularly on the use of alternative feed ingredients or protein substitutes. The specific objectives were to: (i) review the ASEAN-SEAFDEC member country status, constraints associated with developing alternative dietary ingredients for aquaculture feed; (ii) identify specific advances being made in the region with respect to the development of alternative aquaculture feed ingredients; and (iii) define approaches or initiatives supporting catch reduction of low-value/trash fish; (iv) formulate relevant policy recommendations (regional and country-specific) for effective development and utilization of aquaculture feeds; and (v) enhance cooperation among member countries and relevant stakeholders on initiatives that support sustainable aquaculture practices, particularly on feeds. This publication presents the outputs of the RTC. The country reports and review papers presented during the conference which are contained in this volume are cited individually. -

Aquaculture development in Thailand
- In JV Juario & LV Benitez (Eds.), Seminar on Aquaculture Development in Southeast Asia, 8-12 September 1987, Iloilo City, Philippines, 1988 - Aquaculture Department, Southeast Asian Fisheries Development CenterAquaculture practised in Thailand is in the form of pond culture and cage culture in freshwater, brackishwater and coastal areas. The main species cultured include freshwater prawns, brackishwater shrimp, cockles, mussels, and various freshwater and marine finfishes. There is good potential for increased production from freshwater, brackishwater and marine aquaculture. However, the 1983 production of 145 000 mt represents only about 6% of Thailand's total fish production and production in this subsector has fluctuated widely. It will be several years before aquaculture production will contribute substantially to total production. Nonetheless, the culture of high value species of shrimp and fish could contribute significantly to export earnings during the next 5 to 10 years. Conducted primarily by government agencies, research and development are along the lines of increasing seed supply, establishing new culture techniques or improving older ones. The Department of Fisheries (DOF) together with some private companies have ventured into the development and testing of artificial diets for the various cultured species using a variety of indigenous feed stuffs. It is estimated that with adequate investments and appropriate support, aquaculture production will increase from 145 000 mt in 1983 to 378 000 mt in 1991, showing an annual increase of about 13% over this period. Major increases would come from bivalve mariculture (131 000 mt), brackishwater ponds (36 000 mt) freshwater ponds (46 000 mt) and brackishwater cage culture (20 000 mt). -

Use of plant protein sources in aquafeed for high value marine species in ASEAN member states
- In MR Catacutan, RM Coloso & BO Acosta (Eds.), Development and Use of Alternative Dietary Ingredients or Fish Meal Substitutes in Aquaculture Feed Formulation … Ingredients or Fish Meal Substitutes in Aquaculture Feed Formulation, 9-11 December 2014, Nay Pyi Taw, Myanmar, 2015 - Aquaculture Department, Southeast Asian Fisheries Development CenterCultured marine aquatic species are predominantly carnivorous. Major species in the region are seabass, grouper, snapper, tiger shrimp, mangrove crab and abalone. These species, except for abalone, require a high level of dietary protein mostly supplied by marine sources such as fish meal. Global production of marine fish and marine shrimps showed a 3-4 fold increase from 1995 to 2010. For the same period, the usage of commercial feed for production of marine fish and shrimps increased while the fish meal portion in the formulation decreased. This is indicative of fish meal being substituted with alternative sources in commercial feed production, and to some extent the substitution of marine oil which particularly improved the FCR for the marine fish production from 2.0 to 1.9 and for marine shrimps from 2.0 to 1.6. Plant products that include cereal grains, legumes and oilseeds have the most potential among the alternative ingredients for use in aquafeed. The use of these resources for high value marine species is limited due to a variety of anti-nutritional substances they contain. Removal of these substances by processing techniques has improved utilization but with added cost. Hence, fish meal is still the primary source of protein for marine carnivores and its substitution with higher amounts of alternative plant proteins may be difficult compared with lower levels of replacements. The Asian region has accounted for the more than 50% of the total global aquaculture production in 2012 with indications of increased utilization of alternative protein sources in commercial feed production. For the major marine species in the region the increasing trend of plant protein usage with the targeted levels of substitution of fish meal with plant protein sources should be sustainable.
