“…Biochemical studies have shown that zooplankton are rich in protein, lipid, essential amino acids and essential fatty acids which can provide the better augmented growth, immune stimu lation, pigment enhancement, and physiological regulations, it leads to better reproduction of brood-stock prawns and fishes (Watanabe, Kitajima, & Fu jita, 1983;Altaff & Chandran, 1989;Safiullah, 2001). The functional status of the digestive system of larval stages with regard to the digestibility of feed need to be assessed by the successful larval rearing of prawn and fish.…”

The nutritional profiles of wild mixed zooplankton (WM Z) and laboratory cultured Artemia nauplii were compared in the present study. WMZ samples were collected from Sulur lake and Ukkadam lake, Coimbatore, Tamil Nadu, South India. The WMZ from both lakes and Artemia nauplii were utilized for the estimation of biochemical constituents (protein, carbohydrate, lipid, moisture and ash), profiles of amino acids, and fatty acids. Results showed that the total protein content was found to be significantly (P<0.05) higher in WM Z collected from Ukkadam lake, followed by Sulur lake when compared to Artemia whereas, the total carbohydrate and lipid contents were found to be significant ly (P<0.05) higher in Artemia nauplii than WM Z. While, there was insignificant (P>0.05) difference found in ash and moisture contents in all live feeds evaluated. Profile of amino acids and saturated fatty acids were significantly elevated (P<0.05) in WM Z when compared to Artemia. While, in the case of unsaturated fatty acids showed significant (P<0.05) elevations in WM Z of Ukkadam lake followed by Sulur lake and Artemia. The present results revealed that the WMZ has more desirable dietary nutritional characteristics as larval diets than traditional live feed Artemia nauplii.

“…The reproductive system of female calanoid copepod species shows a generalized pattern of having a single median ovary, paired oviducts originating from antero-lateral part of the ovary which leads to the genital segment through the sides of the digestive tract and open into a single chamber, the genital antrum. Though such a generalized female reproductive system is reported in many calanoid species there is considerable species specific variations (Park, 1966;Marshall and Orr, 1972;Corkett and McLaren, 1978;Blades-Eckelbarger and Youngbluth, 1984;Razouls et al, 1986Razouls et al, , 1987Norrbin, 1994;Altaff, 2003Altaff, , 2020Dharani and Altaff, 2004a). The genital antrum has paired dorso-laterally directed pouches, the seminal receptacles in which spermatozoa are stored.…”

Copepods are vital key components of marine and freshwater ecosystems and play vital role in the energy transfer from primary producers to secondary consumers. Their traits like high diversity, different life cycle strategies, sexual reproduction and nutritive value are unique among different zooplankton. In nature, copepods constitute most preferred food of many commercially important marine finfish larvae. Mass culture of copepods is a requisite considering their various applications in aquaculture, environmental monitoring, and pharmaceutical usage. For sustained production of copepods in culture systems there should be proper understanding of their reproductive aspects. In the present study, reproductive biological aspects such as oogenesis, spermatogenesis, spermatophore formation and its transfer to the female of a calanoid copepod, Eucalanus monachus are described. Considering the reproductive features, fecundity, egg size and direct broadcasting of eggs to the medium, E. monachus could be a potential candidate for mass culture and use as live feed in marine finfish larval rearing.

“…They mostly feed on unicellular plants and animals, small metazoans especially other crustaceans as well as organ debris. Planktonic copepods have high nutritive value because of their protein content (Altaff and Chandran, 1989) essential amino acids (Kraul et al, 1993) which greatly enhance their value as live feed in aquaculture. From the ecological point of view cladocera is a crucial group among zooplankton community.…”
