“…This phenomenon holds true in the present study where C. gariepinus fed the ascorbic acid deficient diet had slow growth and poor feed conversion. Works by Durve and Lovell (1982) and Li and Lovell (1985) for Ictalurus punctatus, Hilton et al (1978), Halver (1979) and Sato et al (1982) for Salmo gairdneri, and Mahajan and Agrawal (1980) for Cirrhina mrigala obtained similar results in terms of ascorbic acid requirements of other fish species. Eya and Mgbenka (1990) reported poor growth, hemorrhages and tissue erosion on the edges of the dorsal fins, operculum and pectoral spine in African catfish fed an ascorbic acid deficient diet.…”

“…Ascorbic acid (vitamin C) is an essential water-soluble vitamin for fishes (Lim and Lovell, 1978;Halver, 1979;MacConnell and Barrows, 1993). It is a cofactor in the transformation of proline to hydroxyproline, which is a constituent of collagen and thus necessary for the formation of connective tissues, bone matrix and scar tissue in wound repair (Halver, 1982;Jauncey et al, 1985). It plays an important role in wound healing in coho salmon and rainbow trout (Halver et al, 1969), channel catfish (Lim and Lovell, 1978) and tilapia (Jauncey et al, 1985).…”

As from January 2010 The Israeli Journal of Aquaculture-Bamidgeh (IJA) will be published exclusively as an on-line Open Access (OA) quarterly accessible by all AquacultureHub (http://www.aquaculturehub.org) members and registered individuals and institutions. Please visit our website (http://siamb.org.il) for free registration form, further information and instructions. This transformation from a subscription printed version to an on-line OA journal, aims at supporting the concept that scientific peer-reviewed publications should be made available to all, including those with limited resources. The OA IJA does not enforce author or subscription fees and will endeavor to obtain alternative sources of income to support this policy for as long as possible.

“…Vitamin C requirements vary among species (Halver 1979) and even within the same species maintained under dilTerent environmental conditions. The recommended levels of dietary vitamin C for growing fish determined with chemically defined diets under controlled conditions include the following; 50 mg kg-I diet for salmonidae (Halver.…”

The elTects of dietary levels of L-ascorbic acid (AA) on growth and tissue concentration in juvenile Korean rockfish. Sebastes schiegeli (HilgendorO. were studied. After a 1 week conditioning period. the fish were divided into six groups and given a semipurified diet for 16 weeks. Experimental diets were supplemented with either O. 25. 50. 75. 150 or 1500 mg L-AA kg-I diet (Co. C 2S . C so . C 7S ' C ISO and CISOO). Fish fed C O -C 75 diets showed lower weight gain (WG). feed conversion ratio (FCR). specific growth rate (SGR). protein efficiency ratio (PER) and condition factor than fish fed the C ISOO diet (P < 0.(5). Fish fed the Co diet showed vitamin C deficiency symptoms such as scoliosis. exophthalmia and fin haemorrhage after 12 weeks. After 16 weeks of the experiment. the brain ascorbic acid (AA) concentrations of the fish fed C O -C 75 diets were lower than those of fish fed the C 150 and C I soo diets (P < 0.(5). The muscle and liver AA concentrations of fish fed the Co diet were lower than those of fish fed the CISO and C ISOO diets (P < 0.(5). Broken line analyses for WG. FCR. SGR and PER showed that the optimum levels of vitamin C were 102. 100. 103 and 102 mg AA kg-I diet. respectively. These findings suggest that dietary levels greater than at least 103 mg AA are required for maximum growth and levels greater than at least 1390 mg AA kg-I diet for vitamin C saturation in the tissues of juvenile Korean rockfish.

“…Earthworms have shown to contain essential elements and vitamins recommended for fish physiology, an attribute suitable for small-scale farmers in rural areas where vitamin/mineral premix is scarce and expensive to obtain (Halver, 1979). Eisenia fetida contains recommendable levels of essential micronutrients that are critical for fish growth and development (De Chaves et al, 2015) as shown in Table 2.…”

Use of fish meal in aquaculture is gradually becoming unsustainable due to competition, cost and ecological challenges hence the need to expand the alternative protein sources. The earthworm, Eisenia fetida is among the non‐conventional protein sources, which have been tested with relatively promising results, thanks to its high protein levels, proper amino acid profile, high reproduction rate, low mortalities, fast growth and ease of production. The feasibility of using E. fetida for commercial fish feed production depends on the fundamental knowledge of its growth and reproductive biology, as well as the production methods. On the other hand, the nutritional suitability of E. fetida is determined by its amino acid composition and meal processing methods. Therefore, this study reviews the biological, biochemical composition as well as production and processing methods, as critical aspects for sustainable production and utilization of the earthworm in commercial fish feed production. Further, the study provides some recommendations and options to provide nutritionally complete and economically viable fish feed for efficient and sustainable aquaculture production systems.
