“…The indispensability of phospholipids for Homarus americanus. 10,[18][19][20] In the present crustaceans is assumed to be due not only to its limited ability for phospholipid biosynthesis from fatty acids and/or diglycerides, but also its func tion as an emulsifier of triglycerides and cho lesterol, and as a constituent of lipoproteins essential for the transport of lipids. 15,16,[21][22][23][24] The importance of n-3 HUFA in the diet of P. japonicus larvae and juveniles is well-established and reflects its limited biosynthetic abili ties.12,25-27) Several investigators have postulated that HUFA are involved in some capacity in the reproductive process of penaeid prawns such as P. duorarum,28) P. setiferus,20-31) P. styliros tris,32,33) P. aztecus,31) P. monodon,34) and P.…”

“…However crustaceans only have a limited ability to biosynthesize PL de novo (Shieh 1969;Teshima and Kanazawa 1979;Kanazawa et al 1985), and supplementation of dietary PL therefore appears to be crucial for cultured crustacean species. Although many studies have been conducted on the PL requirements of larval and juvenile crustaceans, such as lobster Homarus americanus (Conklin et al 1980), penaeid shrimp (Chen et al 1993;Coutteau et al 1996;Paibulkichakul et al 1998;Thongrod and Boonyaratpulin 1998), freshwater prawn Macrobrachium rosenbergii (Briggs et al 1988) and mitten crab E. sinensis (Cheng et al 1998a;Wang et al 2004), only limited studies have investigated the dietary PL requirement of crustacean broodstock. Millamena et al (1986) were the first to demonstrate that fecundity and survival rate of Penaeus monodon broodstock were positively affected by the inclusion of soybean lecithin into the diets.…”

The effect of increasing levels of dietary phospholipids (PL) on the ovarian development and reproductive performance of Chinese mitten crab Eriocheir sinensis were investigated using four semipurified formulated diets supplemented with 0%, 1.2%, 2.4%, and 3.6% PL. Four groups of 40 females, with an average individual body weight of 95-120 g, were fed the experimental diets for a period of 7 months. Male crabs were introduced into the female rearing system in March, and mating, spawning, and egg hatching occurred in the following month. After 10 weeks of feeding, females fed the diet with 2.4% PL had a significantly higher gonadosomatic index (GSI) than females fed the diet with 0% PL, whereas females fed the diet with 1.2% PL had a significantly higher hepatic moisture content and lower hepatic lipid content than the other groups (P \ 0.05). After mating, the spawning rate was higher among females fed diets with 3.6% and 2.4% PL (95% and 92%, respectively) compared with females fed diets with 0% and 1.2% PL (both 81%). The results showed that egg production (total number of eggs/female) and fecundity increased with increasing dietary PL level, with females fed diets with 0% and 1.2% PL supplementation having significantly lower values than females fed the diet with 3.6% PL (P \ 0.05). In conclusion, our results suggest that dietary PL supplementation has a positive effect on ovarian development and reproductive performance of E. sinensis broodstock. Further study should aim to investigate the optimal PL level in the broodstock diet of E. sinensis in respect to offspring quality.

“…a mixed diet, gave better growth and survival rates. Lobsters which were fed with artificial diets had lower growth rates (0.05 mm day − 1 ; Conklin et al, 1980;D'Abramo and Conklin, 1985) than with natural foods (0.01 mm day Waddy, 1988). In comparison to natural mixed diets, artificial feeds must be supplemented with balanced nutrients which make them expensive.…”

Improvement of rearing conditions for juvenile lobsters (Homarus gammarus) by co-culturing with juvenile isopods (Idotea emarginata)

Growth conditions of the juvenile lobsters, Homarus gammarus, were optimized in view of a restocking project of the lobster population at Helgoland (German Bight, North Sea) aimed to produce more than ten thousand juvenile lobsters per year. Growth and survival rates of juvenile lobsters depend on diet, temperature and water quality. In the present study, diet at optimum temperature was considered, but special emphasis was placed on the optimization of cleaning and feeding methods from both an economical and ecological point of view. Six dietary treatments of juvenile lobsters (each n = 99) were tested in individual compartments in a semi-closed re-circulation system at around 20°C. Lobsters were fed with combinations of two diets, newly hatched Artemia sp. nauplii and minced crabs Cancer pagurus (whole carcasses), every 2 or 4 days until a carapace length of 10 mm was reached. During the experiment (max. 105 d), juvenile isopods, Idotea emarginata, were constantly present in the lobster boxes. More frequent feeding significantly increased growth rates of the juvenile lobsters while different feeding combinations had no effect. The highest growth rate (0.091 ± 0.02 mm CL day − 1 ) was at a feeding frequency of every 2 days for each diet. At this rate the carapace length of 10 mm was reached in 68-71 days. The survival rate of the juvenile lobsters ranged from 90-97%. The diet consisting of C. pagurus was most cost-efficient and was obtained as discards from the crab fishery at Helgoland. The co-culture of juvenile lobsters with juvenile isopods I. emarginata as "cleaning organisms" was ideally suited for the rearing of lobsters and reduced the maintenance time by 50%. The isopods also served as supplementary diet.
