Live foods in the feeding of aquarium fish larvae

      At reproduction centers, using live food is important, especially when it comes to the first feeding of aquarium fish larvae. Live foods commonly used in the aquarium aquaculture industry include rotifers in two sizes, small types with a size of 50-110 microns, and larger types with a size of 100-200 microns, Artemia, and copepods. Fish larvae in marine aquariums primarily consume copepod...

Vertical distribution of fish larvae in the Canaries-African coastal transition zone, in summer

This study reports the vertical distribution of fish larvae during the 1999 summer upwelling season in the Canaries-African Coastal Transition Zone (the CanariesACTZ). The transition between the African coastal upwelling and the typical subtropical offshore conditions is a region of intense mesoscale activity that supports a larval fish population dominated by African neritic species. During th...

The Marine Fungi Rhodotorula sp. (Strain CNYC4007) as a Potential Feed Source for Fish Larvae Nutrition

Fish oil is used in the production of feed for cultured fish owing to its high polyunsaturated fatty acid content (PUFA). The over-exploitation of fisheries and events like "El Niño" are reducing the fish oil supply. Some marine microorganisms are considered potentially as alternative fatty acid sources. This study assesses a strain of Rhodotorula sp. (strain CNYC4007; 27% docosahexaenoic acid ...

Growth gradients in fish larvae*

Relative growth intensity of various longitudinally measured body segments in larvae of several species of fishes was distributed across the body in a continuous, U-shaped gradient. Juveniles lacked a simple pattern ofgrowth but appeared to grow nearly isometrically. Body depth exhibited a shallow, U-shaped gradient while body width lacked a discernible pattern. Most intense growth, in three or...
