Culture of tropical sea cucumbers for stock restoration and enhancement

Severe overfishing of sea cucumbers has occurred in most countries of the tropical Indo-Pacific. The release of juveniles is being examined at the ICLARM Coastal Aquaculture Centre in the Solomon islands as a means of restoring and enhancing tropical sea cucumber stocks. Sandfish (Holothuria scabra) are the tropical species that show the best potential for stock enhancement. Sandfish are of high value, widely distributed and relatively easy to culture in simple systemss at a low cost. This paper summarizes information about the culture of H. scabra and compares it to that of the temperate species Stichopus japonicus.

Zooplankton population periodicity in a tropical pond

Results of a study on periodicity of zooplankton in small tropical pond are presented. This study was conducted in order to facilitate the design of a pond-based zooplankton production system.

Can the age of the tropical species be determined by otolith measurement?: a study using Pristipomoides filamentosus (Pisces: Lutjanidae) from the Mahe Plateau, Seychelles

The sagittal otoliths of bluespot jobfish (Pristipomoides flamentosus) from the Mahe Plateau, Seychelles, were examined for growth rings using light microscopy. Banding with putative annual and monthly frequency were observed. Consistent age estimates were derived from each of the two patterns. The resulting length-at-age data were use t estimate the parameters K and t sub(0), viz: K=0.33, t sub(0) = 0.16 for males and K = 0.36, t sub(0) = 0.06 for females (using von Bertalanffy plots). Possible causes of the banding are discussed.

Age determination in tropical fish

This essay presents evidence that check marks on the hard parts of tropical fishes can be used for aging these, in spite of the small seasonal temperature and other environmental oscillations prevailing in the tropics. The ideas presented in this article were over 50 years ahead of their time.

Who's working on tropical fish seed transport?

An examination is made of the literature on seed stock and live fish transport in the tropics. ASFA and ICLARM library and professional staff collections were used for the search.
