We examined the effect of dietary eicosapentaenoic acid (20:5n-3, EPA) on growth, survival, pigmentation and fatty acid composition of Senegal sole larvae using a dose-response design. From 3 to 40 days post hatch (dph), larvae were fed live food that had been enriched using one of four experimental emulsions containing graduated concentrations of EPA and constant docosahexaenoic acid (22:6n-3,...

  This study was conducted to evaluate the efficacy of live food (Artemia urmiana) and commercial diet in rearing of Oncorhynchus mykiss larvae. Experiment started when larvae were 0.12g in weight. Triplicate groups of fish were offered one of four treatments: (1) a commercial starter food (2) live Artemia urmiana nauplii (for 3 days) (3) live Artemia urmiana nauplii (for 7 days) and (4) combin...

First feeding of many fish larvae depends on live feed. A comparative investigation the effectiveness different types feed is not available to our knowledge. Hence, we conducted a study examine effect and combinations performance (survival rate, total length, body width, mass, malformation rate) pikeperch, Sander lucioperca, larvae. From day 0 (onset exogenous feeding) 10, saltwater rotifer Bra...

The use of citizen science and opportunity sampling during commercial or tourist voyages can provide valuable insights into the structuring marine plankton community in broad biogeographic areas. With goal studying distribution abundance smaller zooplankton using approach, samples were collected at 33 stations spanning from Arctic to Antarctic cruise S/V “Croatian Tern” (1994-1997), vertical to...

Copepod nauplii are larval crustaceans with important ecological functions. Due to their small size, they experience an environment of low Reynolds number within aquatic habitat. Here we provide a mathematical model swimming copepod nauplius two legs moving in plane. This allows for both rotation and two-dimensional displacement by the periodic deformation swimmer’s body. The system is studied ...

Mosquitoes can transmit the terrible diseases to human beings. Soil-borne fungal products act as potential source for low-cost chemicals, used for developing eco-friendly control agents against mosquito-vector borne diseases. The prime aim of study was to check the larvicidal potential of fungus mycelia (by ethyl acetate solvent) extract from Penicillium daleae (KX387370) against Culex quinquef...
