“…For Penaeids n-3HUFA, particularly EPA and DHA are considered as essential fatty acids (Kanazawa et al, 1979a;1979). The maturation performance and offspring quality of Penaeids are linked to dietary n-3HUFA level (Middleditch et al, 1980;Teshima et al, 1998;Teshima et al, 1989;Xu et al, 1994). In the case of freshwater prawn, n-6PUFA series of fatty acids predominate over n-3HUFA fatty acids (Chanmugam et al, 1983).…”

Fatty acid profiles of midgut gland (MG), ovary and eggs of Macrobrachium rosenbergii of wild and farm reared brooders indicate a significant variation of their components during the sexual maturation and spawning. In both groups, major fatty acids found in the chosen tissues were 14:0, 16:0, 18:0, 18:1n-9, 18:2n-6, 18:3n-3, 20:4n-6, 20:5n-3 and 22:6n-3. Of these, saturated fatty acids dominate over the monounsaturated (MUFA), polyunsaturated (PUFA) and highly unsaturated fatty acids (HUFA). Though all the four groups of fatty acids are found in both groups except n-3 HUFA (P>0.05) other categories are found in higher wild brooders (P<0.05). There was a significant difference in total weight, total length and clutch weight (P<0.05) between farm and wild brooders, but the gonadosomatic index (GSI) and midgut gland somatic index (MSI) did not vary significantly (P>0.05).

Reproduction and feeding habits of Eutropiichthys vacha were studied in Kotri hydrodam, a man-made and human impacted stretch of the Indus River, Pakistan during [2005][2006]. A total 303 specimens were sampled and analyzed for maturity stages and gonadal development and food and feeding habits assessed from gut contents. Results showed male dominance over females: sex ratio 1.16:1.0. Minimum size at sexual maturity was 13.9 cm total length (TL). Mean fecundity ranged 1.38x10 4 to 2.17 x 10 5 . Gonado-somatic index (GSI) was 0.1-2.5 and 0.3-6.5 for males and females, respectively. Highest GSIs were recorded in April. We observe an ontogenic dietary shift in E. vacha: young are omnivorous with insects dominating diet while adults are omni-piscivores with Puntius ticto accounting for 35.4% of species. Other species were Colisa spp., juveniles of Channa spp. and some cyprinids. Feeding intensities were lowest in April at peak of spawning. The intensities increase rapidly after spawning indicating voracious feeding in E. vacha. Feeding intensities in adults are low during the cold season. These results provide for assessment of spatial-temporal variations in feeding intensity in E. vacha while GaSI and diet composition reveal information on environmental shifts and ecosystem fluctuations in the impacted habitats of the River Indus for sound fisheries management.

Penaeid shrimp broodstock nutrition: an updated review on research and development

View full text Add to dashboard Cite

This paper reviews the current knowledge on shrimp broodstock nutrition with special reference to developments during the last decade. Biochemical studies and diet studies are discussed with the aim of identifying the nutrients that are important to sustain optimal shrimp maturation, reproduction and offspring quality. Additionally, an overview is given of the efforts to reveal the nature of maturation-stimulating factors in fresh food, and of the use and performance of commercial and experimental artificial diets. q
