Larval rearing of Asian seabass using protozoa

Seed production of marine finfish in Malaysia is still facing problem particularly live feed for starter diet. Currently, aqua culturists use S or SS type rotifers, which have sizes from 100 to 200μm. Early stage larvae of some marine finfish species select feeds less than 100 μm. Protozoa is a coll...

Fisheries. Angling SH151 Aquaculture - Fish Culture Seed production of marine finfish in Malaysia is still facing problem particularly live feed for starter diet. Currently, aqua culturists use S or SS type rotifers, which have sizes from 100 to 200μm. Early stage larvae of some marine finfish species select feeds less than 100 μm. Protozoa is a collective term of aquatic microorganism that has been identified to be suitable live feed, as their body sizes are less than 100μm. Thus, the objective of this experiment is to compare the survival rates of Asian seabass larvae using rotifers, protozoa, and one kind of protozoa; Euplotes encysticus. Four types of live feed; rotifer, protozoa, E. encysticus, and mixed (rotifer, protozoa, and E. encysticus) were used in this experiment. The experiment was conducted in triplicates. The larvae were fed from 2 to 10 day-after-hatching. Asian seabass larvae were given the same amount of live feed in each larval rearing tank; twice a day. The feeding densities were 20 individual / mL for rotifers, protozoa, E. encysticus, and mixed group. Number of seabass larvae in each group was counted every day and their survival rates were determined. The result from this experiment showed that the survival rates of Asian seabass on 10 day old, the mixed group was significantly higher than other groups. However on 4 day old, the highest survival rate was in E. encysticus group, followed by mixed, protozoa, and rotifer group. Based on the results, recommended live feed was mixed group which consists of rotifer, protozoa, and E. encysticus. 2019-10-30 Conference or Workshop Item PeerReviewed application/pdf en http://irep.iium.edu.my/75973/1/Abstract%20ICOSMAP%20%28Syafiqah%29.pdf application/pdf en http://irep.iium.edu.my/75973/2/Slides%20icosmap2019.pdf application/pdf en http://irep.iium.edu.my/75973/13/iCosMap%20accaeptance%20letter%20Syafiqah.pdf Mohd Shahidin, Syafiqah Hanani and Mohammad Noor, Normawaty and Mohd Idris, Shaharah and Mustafa, Sufian and Mukai, Yukinori (2019) Larval rearing of Asian seabass using protozoa.
