Abstract

Tujuan dari penelitian ini adalah untuk mengevaluasi performa pertumbuhan Gracilaria changii yang ditanam di daerah budidaya dengan lokasi yang berbeda. Penelitian ini dilakukan di perairan Takalar, Sulawesi Selatan, Indonesia. Pengamatan pertumbuhan dengan metode long line dilakukan di lima lokasi di perairan Ujung Baji, Takalar, Sulawesi Selatan. Hasil yang diperoleh memperlihatkan bahwa tingkat pertumbuhan G. changii di lokasi tanam yang berdekatan dengan muara sungai (stasiun-5) memiliki laju pertumbuhan terbaik sebesar 557,6 ± 31,51 g dan berbeda sangat nyata dibandingkan dengan lokasi tanam yang jauh dari muara sungai (stasiun-1) dengan laju pertumbuhan sebesar 266,4 ± 15,98 g. Sedangkan tingkat pertumbuhan spesifik tidak memperlihatkan adanya perbedaan yang nyata antara stasiun-5 (4,20 ± 4,2%/hari) dengan stasiun-1 (2,36 ± 2,4%/hari). Pengamatan kualitas air memberikan indikasi pengaruhnya terhadap pertumbuhan G. changii, di mana yang paling dominan adalah salinitas.This study aimed to evaluate the growth performance of Gracilaria changii cultivated at different locations. This research was conducted in Takalar waters, South Sulawesi, Indonesia. Observations on seaweed growth planted using long line method were carried out in five different locations in the waters of Ujung Baji, Takalar, South Sulawesi. The results showed that the growth rate of G. changii at the planting location near the river mouth (station-5) was the best with a growth rate of 557.6 ± 31.51 grams and significantly different compared to that of seaweed planted at the farthest location from the river mouth (station-1) with a growth rate of 266.4 ± 15.98 grams. There was no significant difference on specific growth rate between stations 5 (4.20 ± 4.2%/day) and station 1 (2.36 ± 2.4%/day). Further observation of water quality variations indicated that salinity predominantly affects the growth. G. changii in this area.

Abstract

Vannamei is a superior commodity of aquaculture in Indonesia. However, production of vannamei only reached 91.5% of the 450.000 tons revised target. Several factors are the cause of the target not being achieved. One of which is a disease outbreak. The use of probiotics as an application that improves the health status of shrimp is a better choice than the use of antibiotics for treatment. The effectiveness of the application of probiotics to control pathogenic microorganisms is highly influenced by the type of bacteria used. This research was conducted to examine the efficacy of using two different types of probiotics with different bacteria compositions on the productivity of vannamei shrimp. The 2.200 m2 pond plots shielded with low-density polyethene (LDPE) were used. The stocking density was 250 fry.m-2. The vannamei shrimp were fed with an artificial diet containing protein from 30-40%, fat form 5%, fibre form 4%, and water content form 11% during rearing. In preparation and maintenance of water management, probiotics A and B. were applied. The results showed that the use of type B probiotics reached better productivity than type A.
