Status of development and use of alternative dietary ingredients in aquaculture feed formulations in Japan: Recent progress of fish meal replacement study of marine fish
MetadataShow full item record
Fish meal (FM) reduction in aquafeeds is one of the most important issues in aquaculture in Japan. The progress in research studies on reducing the amount of FM in aquafeeds has been demonstrated in several marine species in recent years. This report summarizes those on three species which are high-valued and intensively cultured in Japan; namely, the red sea bream, the amber jack and the Kuruma shrimp.

Successful use of cryopreserved oyster trocophores as a live first feed larval marine fish and invertebrates BJ Harvey - In CL Marte, GF Quinitio & AC Emata (Eds.), Proceedings of the Seminar-Workshop on Breeding and Seed Production of Cultured Finfishes in the Philippines, Tigbauan, Iloilo, Philippines, 4-5 May 1993, 1996 - SEAFDEC Aquaculture DepartmentTrochophore-stage larvae of the Pacific oyster Crassostrea gigas were cryopreserved in bulk and stored in liquid nitrogen for periods up to two years before thawing and feeding to a variety of warmwater and coldwater larval marine fish, as well as to marine shrimps and other invertebrates. The commercial product ("TrochoFeed"), marketed in both pre-thawed and cryopreserved versions, has been used successfully in the early rearing of cultured species including red drum, snook, grouper, and black cod, as well as for numerous warmwater and coldwater aquarium display fish. This paper describes the nutritional profile of the cryopreserved trochopores and presents a summary of the available growth and mortality data.
Conference paperPC Liong, HB Hanafi, ZO Merican & G Nagaraj - In JV Juario & LV Benitez (Eds.), Seminar on Aquaculture Development in Southeast Asia, 8-12 September 1987, Iloilo City, Philippines, 1988 - SEAFDEC Aquaculture DepartmentMalaysia is a fish-consuming country with fish representing 60% of a total animal protein intake. At an annual per capita consumption of 32 kg some 560 000 mt of fish is required for the projected of 17.5 million people in year 2000. Coastal marine capture fisheries, the mainstay of Malaysia's fishsupply, has not shown any increase in landings over the last few years. In fact in 1985 there was a decline of 3.7% compared to 1984 fish landings. This declining contribution of marine fisheries is compensated by an increase in aquaculture production. In 1985, aquaculture contributed 51 709 mt to the total fish supply. This represents 10% of the total fish landings of 514 570 mt or 13% of total table (edible) fish landings. Malaysia does not have a long standing aquaculture tradition unlike its neighbours in the Indo-Pacific. Even then, the industry has seen rapid growth in the last few years. Today there are 19 species of finfishes, crustaceans and shellfish cultured in the country. The main freshwater fish species bred and cultured are bighead carp (Aristichthys nobilis), grass carp (Ctenopharyngodon idella), common carp (Cyprinus carpio), Indonesian carp (Punctius gonionotus), catfish (Clarias macrocephalus and Pangasius spp), snakefish gourami (Trichogaster pectoralis) and tilapia (mainly Oreochromis niloticus). Marine finfishes bred and cultured are sea bass (Lates calcarifer), grouper (Epinephelus sp.) and snapper (Lutjanus johni). Penaeus monodon is the dominant marine prawn species bred and cultured but culture of P. merguiensis is receiving considerable interest. Macrobrachium rosenbergii is the only freshwater prawn cultured commercially. Molluscs cultured are the blood clam (Anadara granosa) and the green mussel (Perna viridis). In 1985, blood clam and mussel culture accounted for 87% of all aquaculture production of Malaysia, freshwater fish 12%, floating cage culture of marine fish 0.7% and brackishwater pond culture 0.3%. In terms of value blood clam and mussels represented 30% (M$15M) of total value (M$49.5M), freshwater fish 57% (M$28M),cage culture of marine fin fishes 7% (M$3.4M),and brackishwater pond production 6% (M$2.1M). Aquaculture in Malaysia has considerable growth potential. It is projected that 22 000 ha of mangrove will be opened by the year 2000 for shrimp culture. Some 330 000 m2 of protected coastal waters have been identified for cage culture. Some 6500 rafts can considerably expand the present capacity. In freshwater culture about 8000 ha of land and 17 500 ha of mining pools can be developed while 200 000 ha of artificial lakes and impoundments for freshwater fish cage culture are available. Yet such development is not without constraints. Freshwater finfish culture is hampered by lack of good quality broodstock. There is also a limited market for freshwater finfishes. Marine finfish culture is limited by lack of fingerlings and good quality compounded diet to replace trash fish which is deteriorating in quality and quantity. Marine prawn culture is heavily dependent on wild spawners, the supply unpredictable and inadequate. Acid sulfate soil continues to cause the deterioration of brackishwater ponds. Cockles and mussels can be sold to export markets only if they meet specific quality standards.
Conference paperMR Catacutan - 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.
