Effects of five different diets of green microalgae, Scenedesmus quadricauda (S), poultry manure (P), cattle manure (C), and two mixed diet of P+C (PC) and S+P+C (SPC); and interaction effects of water temperature (20, 25, 30°C) and photoperiod (24:0, 0:24, and 12:12, hours light: hours dark) on production and growth of Ceriodaphnia quadrangula were examined separately. Then, mass cultivation of C. quadrangula and its application for rearing of an ornamental fish larva, Mayan cichlid (Cichlasoma urophthalmus) were carried out. Results showed that mean population density and specific growth rate (SGR) of C. quadrangula obtained 0.15-3.70 ind. mL -1 (150-3700 ind. mL -1 ) and 0.019-0.18 day -1 , respectively, maximum with S diet and minimum with C diet. The better mean population density and SGR for C. quadrangula determined at interactions 25 ºC with 24:0 and 12: 12, L:D, respectively, which was significantly higher than that at interactions 20 ºC and 30 ºC. Nutritional analyses showed that protein and lipid contents of C. quadrangula were 54% and 12.3% dry weight, respectively. The fatty acid contents of C. quadrangula were 27.3% and 63.7% of saturated and unsaturated fatty acids, respectively. Among PUFAs (Polyunsaturated Fatty Acids) content, 18:2n-6 and 18:3n-3 were in highest level. Early cichlid larvae (5-weeks-old, 15.8 mm length and 110 mg weight) and advanced larvae (10-weeks-old, 25.6 mm length and 240 mg weight) consumed C. quadrangula at range 220-584 ind. day -1 larvae -1 and 528-1956 ind. day -1 larvae -1 , respectively, as well as suitable growth and survival rate. This study demonstrated that C. quadrangula could be used as live feed purposes for larval rearing in aquaculture.

“…Continued refinement of these groups may necessitate the inclusion of additional data, such as those regarding life history. Moenkhausia sanctaefilomenae has been the subject of various life history studies, most of which have focused on reproductive behaviors and larval feeding strategies (Borges et al 2000;Lourenço et al 2008;Alanis et al 2009;Tondato et al 2010). This article presents the early ontogeny of M. sanctaefilomenae.…”

Early ontogeny of aquarium-raised Moenkhausia sanctaefilomenae (Characiformes: Characidae)

The ontogeny of the characiform fish Moenkhausia sanctaefilomenae, from early embryogenesis through the early larval period, is presented. Fertilized eggs were slightly elliptical, measured 0.6 mm in diameter, and were surrounded by a fertilization envelope 0.8 mm in diameter. Much of the early embryogenesis is complete after 12 h, with cleavages complete after 2.5 h and gastrulation complete after 3 additional hours. The initial formation of organs needed for predatory behaviors occurs within 72 h. Growth of the cranial elements is quite dramatic and allows for the capture of relatively large prey at the onset of exogenous feeding. Elaboration of these elements continues into the early larval period.

Three different live diets, Eucyclops serrulatus, Ceriodaphnia quadrangula and equal combination of E. serrulatus copepodid and C. quadrangula, were offered to angelfish (Pterophyllum scalare) larvae viz 1-week, 2-week and 3-week old at prey densities of 2, 5 and 10 individuals mL À1 . Results showed that 1-week-old P. scalare larvae consumed E. serrulatus copepodid at a rate of 31.3-56.7 ind. h À1 , C. quadrangula at 8.0-12.0 ind. h À1 , and mixture of E. serrulatus and C. quadrangula at 20.7-40.7 ind. h À1 . For 2-week-and 3-week-old larvae, consumption rate increased accordingly. The electivity indices (E) of P. scalare (1-week-old larvae) for E. serrulatus copepodid were +0.18, +0.23 and +0.22 at prey densities of 2, 5 and 10 ind. mL À1 respectively. Tendency towards E. serrulatus copepodid consumption reduced by aging P. scalare as indicated by the E values for 2-and 3-week-old larvae. However, growth and survival of P. scalare larvae was greatest when fed on combination of copepod E. serrulatus and C. quadrangula.
