Abstract

Fry requirement to embank one is at Indonesia as much ± 11 Billion / years withassuming that diffusion average for every ranging hectare among 2.000 – 3.000fries / Ha / M.T. Fry haul of salt water varying bases season, ranging 500 800million number. fry / yr, so can't expect to meet the need fishpond farmer.hatchery's production exhaustive Indonesia, just can supply 16,6 % of farmerneed. Far ranging productive fishpond at south Sulawesi ± 64.000 ha with fry theneed ± 600 million, number / yrs. (2 MT /'S times Yrs.s), gotten from hatchery'sproduction that is at South Sulawesi and south Sulawesi extern, and the capturerfry of nature. Fry requirement embanks at South Sulawesi to be accomplished43,42 %, Fries lacking picture shrimp that needed will the greater if diffusion beincreased By Problem fry procurement to embank at South Sulawesi to experiencedilemma among farmer embanks at one hatchery's party and entrepreneur inopposition. Farmer embanks to perceive fry lack at stated periods, hatchery'sentrepreneur on the contrary excess fry did not even saleable absolutely at statedperiods. This research aims to know operational system problem hatchery who isat South Sulawesi.

Abstract

Transferring periodically of rearing shrimp between plots of land, anaquaculture technology to increase productivity of shrimp pond, was calledmodular system. The research was applied on 15 pond with 250 m2 of each thatwas separated on 3 category including A, B and C categories. 4, 6 and 8 larva/m2(PL40) was distributed on each of A, B and C category. During 90 rearing days,the larvae were supplied by means of production such as dolomite, organicmanure of chicken fesses and pathogen/pest control (saponim). The B – categoryshowed the highest average product of 19,36 kg/plot while C – category of 16,69kg/plot and A – category of 15,73 kg/plot. While the best production was shownby A- category, 4 larva/m2 , with total average product was 15,73 kg/ 250 m2 if theproduction conversed to 1 ha, the highest product is in A- category/treatment (4larva/m2), with average benefit cost is Rp. 21.494.250,- per season . B/C ratioanalysis shows point number higher than 1, which indicated that the aquaculturewith modular system is potential to implement. Suggested that larva content onaquaculture activities of tiger prawn in brackish ponds without water wheel(kincir) is 4 larva/m2.
