The harlequin shrimp growth ratio was decrease with the increase size. Max carapace length about 13mm. The carapace length over 10.5mm could hatch over 3000 larvae. The shrimp spawning again after hatched 1-2day.
Newborn seahorses were fed of copepoda immediately which food density was 5 inds/㏄ and add more copepoda if the food density too low at noon. The detritus and dead seahorses in the bottom of FRP tank should be removed twice a day in order to keeping the water clean.
This study was to explore the culture and propagation technique of freshwater stingray. At present, we have been kept about 40 freshwater stingray, and measurement of fish body length and weight regularly to explore the growth of fish. Some stingray already mature, may engage in reproduction test . The water temperature controlled at 27 ℃, we can maintain the normal activity and growth of freshwater stingray.
This project has established technologies of breeding anemonefish. Currently, 180 pairs of brooder on 16 species of anemonefish have been successfully reared. Among them, 36 pairs have started spawning. And more than 55,000 young fish (＞1.5 cm) were produced.
In this study, we collected samples from 10 ornamental fish farms and obtained 65 cases（45 cases from freshwater ornamental fish and 20 cases from seawater ornamental fish）from distinct geographic regions of the east and south Taiwan in 2009.
Set up the technique of packaging anemone fish at least 5 species in long-distance transportation. Pre-transport fasting, 30‰ salinity, 22℃ clean sea water, single packing and specific kind and concentration anesthetics apply to the packaging process and keep the survival ratio above 80％. Adsorptive substance cannot raise the survival ratio.
