Water Quality Variable

FCR or feed conversion ratio is one of the strategic indicators on pond production which is very important for determining the costs incurred during the shrimp culture period. The purpose of this study was to examine the relationship between water physico-chemical parameters and the conversion rate of shrimp feed in intensive shrimp ponds (Litopenaeus vannamei). The research method used in this study is the ex-pose facto design during shrimp culture cycle with uniformity of treatment during the cultivation process, then the research collective data obtained periodically is analyzed by multiple linear regression. The results of this study indicate that all pond water quality variables based on quality standards are still in accordance with the standards intended for aquaculture. While based on regression analysis and t-test, the temperature variable is the only parameter that has a direct influence on the FCR efficiency by shrimp. As well as temperature, salinity, and alkalinity variables are parameters that have a close level of relationship to the FCR value in the ponds of 84.1%, 79.1%, and 69.9%. The conclusion of this study is that in intensive ponds the parameters of temperature, salinity, and alkalinity are water quality parameters that have a close relationship with the efficiency of FCR values ​​in ponds, with temperature parameters being the water quality variable which has a direct influence on the effectiveness of the feed conversion ratio by shrimp.

Salah satu jenis udang yang cukup potensial untuk dikembangkan adalah udang vaname (Litopenaeus vannamei). Budidaya ini berkembang dengan teknologi intensif, namun terbatas pada golongan masyarakat menengah ke atas (padat modal). Riset ini bertujuan untuk mendapatkan data dan informasi pengaruh penggunaan tokolan terhadap produksi, Rasio Konversi Pakan (RKP) pada pembesaran udang vaname teknologi intensif. Riset ini dilaksanakan di tambak Punaga, Takalar, Instalasi Balai Riset Perikanan Budidaya Air Payau (BRPBAP), menggunakan empat petak masing masing berukuran 4.000 m2/petak. Hewan uji adalah udang vaname dengan perlakuan: (A) pembesaran dengan tebar benur (PL-12), dan (B) pembesaran dengan tebar tokolan (PL-27). Setiap perlakuan dengan 2 ulangan, kepadatan benur dan tokolan adalah 50 ekor/m2, dan pemeliharaan berlangsung 80 hari di tambak. Hasil yang diperoleh pada perlakuan B memperlihatkan pertumbuhan mutlak (11,114±0,258 g/ekor), sintasan (92,55±0,23%), produksi (2.087,5±88,2 kg/petak) lebih tinggi daripada perlakuan A yaitu: pertumbuhan mutlak (10,085±0,120 g/ekor), sintasan (90,83±8,51%), produksi (1.831,0±149,9 kg/petak), namun ketiga peubah ini berbeda tidak nyata antara kedua perlakuan. RKP lebih rendah pada perlakuan B (1,096±0,034) berbeda nyata dengan perlakuan A (1,257±0,048). Peubah kualitas air memperlihatkan sebaran kisaran yang merata untuk kedua perlakuan, kecuali nitrit (NO2) memperlihatkan kisaran yang tinggi pada perlakuan B (0,18235 mg/L) dibandingkan dengan perlakuan A (0,0328 mg/L) pada akhir penelitian. Hal ini disebabkan waktu panen yang berbeda sesuai dengan kondisi musim yaitu kualitas air sumber semakin menurun. Kualitas air sumber yang menurun ini diikuti oleh meningkatnya total vibrio di air laut mencapai; 4,33104 cfu/mL dibandingkan dalam air tambak 829.102 cfu/mL. Kesimpulan memperlihatkan bahwa penggunaan tokolan (PL-27) menghasilkan produksi yang tinggi dan rasio konversi pakan yang rendah.One species of shrimps that has the potential to be developed for aquaculture is whiteleg shrimp (Litopenaeus vannamei). The recent cultivation method has been developed using intensive technology, but can only be afforded by middle and upper social groups (capital intensive). This research was aimed to study the influence of using shrimp juvenile on the production and feed conversion ratio of whiteleg shrimp cultured in intensive system. The research was conducted at the research installation of the Research Institute for Coastal Aquaculture in Punaga, Takalar Regency. Four  ponds each sized of 4,000 m2 were used in this research. The treatment was applied i.e grow-out of post-larvae 12 (PL-12) (A) and grow-out of shrimp juvenile (PL-27) (B) each with stocking density of 50 ind./m2. Each treatment was arranged in two replications and reared for 80 days. The results obtained in treatment B showed that absolute growth (11.114±0.258 g/ind.), survival (92,55±0,23%), and production (2,087.5±88.2 kg/pond) was higher than those of in treatment A (absolute growth, 10.085±0.120 g/ind., survival rate, 90.83±8.51%, production, 1,831.0±149.9 kg/pond), but all parameters were not significantly different between both treatments. Feed conversion ratio (FCR) was lower in treatment B (1.096±0034) and significantly different with treatment A (1.257±0.048). Water quality parameters showed similar variations in both treatments, except Nitrite (NO2) where a high range of Nitrite variation was recorded in treatment B (0.18235 mg/L) compared to treatment A (0.0328 mg/L) at the end of research. This was due to different harvest times in accordance with the conditions of the season where at a particular time, the quality of water source was decreasing. The decrease of water quality was followed by the increase of total vibrio in seawater reaching 433104 CFU/mL than in the pond water 829.102 CFU/mL. The conclusion is that using the shrimp juvenile, PL-27, high shrimp production and low RKP can be achieved.

The traditional method of shrimp culture is a common practice in Indian Sundarbans which is done without any sound scientific back-up, proper feed, and water quality management. The shrimp farmers use a traditional feed of animal origin that often results in deterioration of water quality and disease outbreaks in cultured species. The present paper highlights the effect of the total replacement of animal ingredients in shrimp feed with floral ingredients on water quality and shrimp health. Weight gain, condition index, feed conversion ratio (FCR), survival, body pigmentation (astaxanthin level) were analyzed in shrimps along with pond water quality. Higher condition index (C.I.) values, survival rate, and gain in shrimp weight were observed in the experimental pond (E) compared to the control pond (C). Low FCR values were observed in the experimental pond than in the control pond. Astaxanthin values in shrimps of the experimental pond were also higher than the control pond which points towards Suaeda maritima as the source of carotenoid in the shrimp tissue.

Barb (Barbonymus balleroides Val. 1842) is one of the native species found in many rivers of Asian countries, including Indonesia. This species had higher commercial value compared with other fish species popular among consumers. In terms of supporting its domestication, information regarding the optimal aquaculture system of the fish is needed, one of which is its rearing location. Currently, there is limited information on rearing the fish at different locations with different altitude. This research aimed to obtain the growth of barb fingerlings reared in three locations with different altitudes. The study was conducted in the ponds located at Cijengkol area (ASL<200 m), Maleber (200 m<ASL<400 m), and Ciherang (ASL>400 m), West Java. Fingerlings of domesticated barb (total length 4.48 ± 0.10 cm; weight 0.95 ± 0.06 g) were stocked in three fixed net cages (size 2 m × 2 m × 1 m) in a pond (40 m × 20 m) at each location. Fish were fed with commercial feed (30% protein) of 5% biomass three times per day during 120 days of rearing. Water quality parameters observed were temperature, dissolved oxygen, and pH. Measured parameters were length gain, weight gain, specific growth rate, average daily growth, biomass gain, feed conversion ratio, and survival rate. The results showed that the fish reared in Maleber showed the best growth and feed conversion ratio compared to other locations (P<0.05). Meanwhile, no significant differences were found on the survival rate within all treatments. The growth of barb fingerlings is more optimal if reared in midland areas which have suitable temperature ranges for their growth.
