| Abstract | The research carried out in this thesis involved an assessment of milkfis h farming practices in East J ava a nd experiments to compare the performance of hatchery-reared and wild milkfish fry. The field s urvey of milkfis h farmers in East J ava (regencies of Gresik and Sidoarjo) was carried out t o asses curre nt milkfis h culture practices a nd con straints. A total number of 277 fis h farmers have bee n surveyed in which onl y 12% of them c ulturing milkfish single species and the rest have shifted to more profitable polycult u re system. It was also disclose d that 2% of them operating within extensive system a nd the r est was semi- inte n s ive. Milkfish culture was u sed to produce t able fis h, bait fis h and finge rlin g . Economical rather than technical aspect was the ma jor curre n t impediments faced b y fish farmer s . Climbing prices of inputs and marketing of product are the most serious constraints. Stress tests involving salinity, te mperature and transportation s hock, a nd grow-out experiments in nursery hapas were carrie d out using h atcheryr ear e d milkfish fry (produce d by Gondol Research Station for Coastal Aquaculture Bali) and wild-cau ght fr y from north ern and southern coastal water s of Bali, Indonesia. Salinity s h ock from 20 ppt to O, 10, 30 and 40 ppt, temperature s t ress from current room temperature to 16.2- 16.8 °C and 36.6- 37.0 0C over 6, 12 a nd 24 h our periods , a nd tra n sportation shock carrie d out over 6-12 hours s howed that there was n o s ig nificant difference between hat chery-bred a nd n atural milkfish fry. The result of the field-based experiment in hapas showed that, contrary to the perception of farmers, there was n o s i g nificant difference in terms of growth and s urv ival between the hatche ry- bre d and natural milkfis h fry. |
