Salah satu program dari Gubernur Sulawesi Selatan periode 2018-2023 adalah mengembalikan kejayaan udang windu di Sulawesi Selatan. Telah dilakukan kegiatan yang bertujuan mengetahui performa budidaya udang windu di tambak pembudidaya yang dilaksanakan pada musim kemarau tahun 2019 di Kecamatan Marusu Kabupaten Maros. Kegiatan budidaya udang windu teknologi tradisional plus dilaksanakan di tambak Dusun Kurilompo, Desa Nisombalia Kecamatan Marusu Kabupaten Maros. Sebanyak enam petak tambak pembudidaya ditebari tokolan udang windu dengan padat penebaran dari 10.000 sampai 30.000 ekor/ha. Setelah dipelihara selama 69 sampai 80 hari dilakukan panen dan selanjutnya dilakukan penentuan sintasan, bobot rata-rata, produksi udang windu, dan rasio konversi pakan (RKP). Data yang diperoleh dianalisis secara deskriptif. Hasil kegiatan menunjukkan bahwa kualitas air di tambak Kecamatan Marusu, Kabupaten Maros pada musim kemarau dicirikan dengan salinitas yang berkisar antara 36,63-69,40 ppt; suatu kondisi yang tidak optimal untuk budidaya udang windu. Pada saat panen didapatkan sintasan udang windu dari 27,57% sampai 66,67%; bobot rata-rata dari 14,29-40,00 g/ekor; produksi dari 90,1-800,0 kg/ha/musim; dan RKP dari 0,54:1 sampai 2,10:1. Disimpulkan bahwa budidaya udang windu di tambak bersalinitas tinggi di daerah ini merupakan penyebab utama rendahnya sintasan, bobot rata-rata, produksi udang windu, dan RKP. Direkomendasikan bahwa perbaikan budidaya udang dengan menjaga tingkat salinitas dalam nilai optimal harus disosialisasikan kepada pembudidaya udang windu di daerah tersebut.One of the main aquaculture development targeted by the South Sulawesi Province for the period 2018-2023 is to restore the glory of tiger shrimp farming in South Sulawesi. The recent study was carried out to uncover redevelopment opportunities of tiger shrimp culture and determine the performance of tiger shrimp culture in the farmers’ ponds. The study was performed during the dry season in Marusu Subdistrict Maros District, in 2019. Traditional plus tiger shrimp farming activities were carried out in the ponds of Kurilompo Subvillage, Nisombalia Village, Marusu Subdistrict, Maros District. A total of six brackishwater ponds were stocked with tiger shrimp fingerling with stocking densities of 10,000-30,000 ind./ha. After being cultured for 69 to 80 days, the shrimp were harvested and measured their survival rate, average weight, production of tiger shrimp, and feed conversion ratio (FCR). The data obtained were analyzed with descriptive statistics. The results showed that water quality in brackishwater ponds of Marusu Subdstrict Maros District, in the dry season is characterized by salinity ranging from 36.63 to 69.40 ppt, a condition that is not optimal for tiger shrimp culture. At harvest, the survival rate, average weight, production, and FCR of the farmed average tiger shrimp were 27.57%-66.67%, 14.29-40.00 g/ind., 90.1-800.0 kg/ha/season, and 0.54:1-2.10:1, respectively. It is concluded that the culture of tiger shrimp in the brackishwater ponds with high salinity in this area is the primary cause of poor survival rate, average weight, production of tiger shrimp, and FCR. It is recommended that culture shrimp improvement via maintaining salinity level within the optimal values has to be disseminated to the fish farmers in the area.

Blue shrimp disease is one of the main problems in tiger shrimp culture. It reduces shrimp quality which eventually will decrease its market price. Blue shrimp is caused by deficiency of nutrition and additive materials such as carotene and other nutrient which function as vitamin source for important metabolic processes and formation of color profile in shrimp and fish. The aims of this study were to study the application effect of carotenoid extract of sponge Callyspongia basilana, as an additive material on the ability of shrimp to get back to normal state after suffering blue shrimp disease and survival rate of shrimp and to find out the optimal concentration of sponge carotenoid extract to cure the diseased shrimp. This study was consisted of two steps namely; (1). Extraction of sponge carotenoid by maseration and fractionation using acetone and petroleum ether solvents and (2), the application of carotenoid extract on the diseased shrimp. The research was arranged in a complete randomized design with four experiments consisted of (A). Control (without carotenoid extract); (B),(C), and (D) carotetoid extract addition of 3 mg/L, 6 mg/L, and 9 mg/L respectively with three replication each. The test animal used were blue diseased tiger shrimp with the density of 15 ind./container having 7.5–9.5 cm in size and the average weight of 5.5–10.0 g. The study showed that Callyspongia basilana carotenoid extract was able to change blue diseased shrimp to be normal within six days at the concentration of 9 mg/L. The highest survival rate was found in the experiment D (93.3%). Meanwhile, the lowest was obtained by the control population (13.3%) and the other two treatments were 80.0%(C) and 73.3% (B). The average of water quality parameters such as temperature, dissolved oxygen, pH, salinity, nitrite, and ammonia were in the suitable range for the growth and survival rate of tiger shrimp.

Abstract Tiger shrimp (Penaeus monodon Fab.) is one of important commercial species in Indonesia. Low quality of shrimp fry due to the lack of good quality broodstock availability is shrimp cultivation problem that need to be solved. The study was aimed to evaluate growth and survival rate of broodstock candidate of transfection and non-transfection tiger shrimp. The study was conducted using four ponds with 2000 m2 in size in Takalar Regency. South Sulawesi. The treatment were A = transfection tiger shrimp broodstock candidate and B = non-transfection tiger shrimp broodstock candidate. Approximately 19.0-21.9 g/ind of shrimp were reared in 60 days in 0.25 individu/m2 (500 individu/2000 m2) stocking density. Commercial pelleted feed which content 38% of protein was fed three times a day in 5-3% of body weight dosage. Measured variables were growth performance, size distribution and survival rate. The result showed that shrimp growth were no significantly different (P>0.05), while survival rate and size distribution were significantly different (P<0.05). The dominant size of transfection shrimp was 41-50 g/ind. Whereas, non-transfection shrimp was dominated by 31-40 g/ind in size (48.39%). Survival rate of tiger shrimp broodstock candidate in this study ranged from 30.80 to 64.10%.

Abstract The objective of the research are to monitor of floc and same parameters production of Litopenaeus vannamei cultured in concrete pond. Two unit of concrete ponds consist of one pond real conccrete pond cemented in the dike and pond bottom, it size 3250 m2 (A pond) was stocked with vanname post larvae day 10 at density 170 ind./m2 (561.200 ind.). The other one pond only cemented in the dike, whereas the pond bottom still of sandy soil, its size 3915 m2 ( B pond) was stocked with vanname post larvae day 10 at the density 148 ind./m2 (579.600 ind.). These ponds were monitored started from pond preparation stages untill shrimp harvested. In A pond , after two months shrimp cultured, at every two days the pond waters was added 15 kg of molasses in order to enhance the CN ratio, so that the floc can growth easily. B pond was control pond without molasses addition. Both of these ponds were added with varies of probiotic shifted daily. Monitored on srimp feed given to the shrimp showed that after post larvae stocked in pond, the feeed given to the post larvae at the dosage 3 kg crumble feed/100.000 ind. post larvae. The quantity of shrimp feed increases to 6 kg/100.000 ind post larvae at the day of culture 20 - 25. Then after that period the quantity of feed given to the shrimp follow the standard feeding program and depend on the feeding monitoring in trays (anco). Shrimp survival rate, production and feed convertion were monitored after shrimp harvested. Water quality, total bacteria and total Vibrio sp were monitored beweekly. TSS, VSS and floc volume were monitored after floc develop in pond waters. Result of the research showed that floc develop in A pond at the day 75, while in B pond after the day 90. Ammonium concentration in pond waters was decreases coinsides with the developing floc in A and B pond. However, nitrite decreased only in B pond and Vibrio sp population was stagnant. Shrimp harvested in both ponds at two times, first at the day 110 and secondly at the day 140. Shrimp production attained 11.123,5 kg (34.226,15 kg/Ha), survival rate 88,55%, feed convertion 1 : 1,82 and shrimp size 41,7 – 52 ekor/kg in pond A. In B pond shrimp production is15030 kg (38.390,8 kg/Ha), survival 99,6%, feed convertion 1 : 1,66 and shrimp size 36,5 – 46,5 ind./kg. Based on this research indicated that in A pond more fasted floc develop compared than that of B pond. However, shrimp production was lower, feed convertion was higher in A pond compared than that of B pond. Total yields in plots A (flock) of 11123.5 kg (34226.15 kg / ha), with 88.55% survival rate, feed conversion 1: 1.82. The average size of 46 shrimp tails / kg. In plot B the production of 15 030 kg (38390.8 kg / ha), 99.6% survival rate, feed conversion of 1.66, the size of the shrimp tails 41.5 / kg. Based on these results suggest that although the plot A flock is formed faster than in plot B, but lower shrimp production and feed conversion value is higher than that obtained in plot B. The analysis focused on the cultivation of farms with the highest production of plot B is converted in a total of 36 308 kg ha (an average of 34226.15 kg / ha - 38390.8 kg / ha) with a value of Rp. 805.465.160/season. Vaname shrimp farming can be done two times a year. Reveniu calculation cost ratio (R / C ratio) value of 2.02 indicates the feasibility of (2.02> 1) in a season of business, while for the Benefit cost ratio (B / C ratio) of 1.02 (1.02> 1) is worthy of sustained effort.

Abstract Hai Phong province is one of the main shrimp culture areas in north Vietnam. Its climate is influenced by two monsoon regimes. The April-September southwest monsoon is wet and hot, and the temperature is suitable for shrimp culture. The October-March northeast monsoon is dry and cold, and the temperature is not suitable for shrimp culture. Different shrimp farming systems take place along the entire coast depending on socio-economic and climatic conditions, seed availability, and farming methods to minimize the operating risk. The main cultured species in Hai Phong is black tiger shrimp, Penaeus monodon. The shrimp are either cultured in monoculture or integrated or cultured alternatively with mud crab (Scylla serrata), greasyback shrimp (Metapenaeus ensis)and seaweeds (Gracilaria gracilis and G. blodgettii). The main crop of black tiger shrimp is from April to September, when about 15% of farms practice integrated shrimp-seaweed culture and 85% of farms practice shrimp monoculture. Additional crops of shrimp or mud crabs are cultured during other months from September to March, while seaweed production is integrated with shrimp or crabs all year. Thus, four main shrimp farming systems can be found in Hai Phong: Single-crop shrimp farming, double-crop shrimp farming, shrimp-crab rotation farming, and integrated shrimp-seaweed-crab farming.

Study Results

Vibriosis is one of main diseases of the black tiger shrimp Penaeus monodon infected by pathogenic bioluminous bacterium Vibrio harveyi that can cause mass mortalities in shrimp culture. The bacteria can also trigger the disease white spot syndrome virus (WSSV). An effort to produce shrimp disease-resistant strains has been done through transgenesis technology with antiviral gene transfection. By this technology, it is expected an increase in the immune response of shrimp in a variety of diseasecausing pathogens. This study aimed to determine the immune responses (total haemocytes, haemocyte differentiation, and phenoloxydase activity) of transgenic tiger shrimp against pathogenic bacterium V. harveyi. Research using completely randomized design, which consists of two treatments and three replications. Test animals being used were transgenic and non-transgenic shrimp with size, weight 3.93±1.25 g and a total length of 7.59±0.87 cm. Treatments being tested were the injection of bacterium V. harveyi (density of 5x106 cfu/mL) of 0.1 mL/individual on transgenic (A) and non-transgenic shrimp (B). Immune response parameters such as total haemocytes, haemocyte differentiation, and phenoloxydase activity were observed on day 1, 3, and 6 days after challenging. Data were analyzed using t-test by SPSS software. The results showed that the total haemocyte of transgenic shrimp was not significantly different (P>0.05) from non-transgenic shrimp, but haemocyte differentiation and phenoloxydase activity were significantly different (P<0.05) especially on sixth days after being exposed to the bioluminescent bacteria. The study results implied that transgenic shrimp has a better immune response compared than non-transgenic shrimp.
