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.

Utilization of ex-sand pit lakes for aquaculture is difficult due to low water quality and high concentrations of iron (Fe). Phytoremediation using aquatic plants has been proven to be effective in reducing Fe in waters. This study aims to determine the growth, feed conversion efficiency and survival rate of tilapia (Oreochromis niloticus) cultured with ex-sand mining water media with phytoremediation treatment. Phytoremediation treatment was carried out by Eichhornnia crassipes, Azolla pinnata, and Salvinia molesta. Fish culture experiments were carried out in plastic tarpaulin tanks for 40 days, with ad satiation feeding, three times a day using the commercial feed. The results showed that phytoremediation with aquatic plants had succeeded in reducing Fe to a level suitable for fish culture. Fish culture experiments showed an absolute length growth rate of 0.09-0.18 cm/day and an absolute weight growth rate of 0.11-0.16 g/day. The feed conversion ratio was 1.18-1.40 and the survival rate was 98.04-99.08%. The survival rate of tilapia is high, the feed conversion ratio is medium and growth is low. The high environmental temperature and the decrease in water quality due to the absence of water changes and aeration are suspected of causing the low growth of fish. Therefore, further research with water change and aeration experiments and the use of other species of fish is needed to follow up the results of this study.

The efficiency of feed is considered as one of the most crucial factors that affects the growth performance, feed conversion ratio and yield as well. The study was aimed to compare the growth parameters of tilapia at different stocking densities to detect the efficiency of sinking feed assessing the growth trends at various sampling stages. To evaluate the comparative yield, the study was carried out in twelve concrete tanks under an outdoor laboratory shed. Tilapia (Oreochromis niloticus) fry was released at the rate of 8 fry per tank as per the recommended stocking density of 320 fishes/decimal and 4 fry per tank equivalent to the stocking density of 160 fishes/decimal in intensive and semi-intensive aquaculture system, respectively. To evaluate the growth trends sinking feed was used for feeding the fish during the experimental period for T1 (Intensive) and T2 (Semi-intensive), respectively. The feed was supplied in each with three replications at the rate of 20%, 15%, and 10% of the body weight of fish, respectively. The daily ration of feed was delivered to fish dividing into two parts daily. Aeration facilities using air stone aerator were installed for 24 hours. To assume the consecutive growth trends, weight of fish was recorded in 3 days interval to have better understanding on the yield performance in relation to the feed conversion ratio (FCR). Water quality parameters i.e., temperature and dissolved oxygen (DO) were recorded two times daily. The final weight gains of fish were 133.77±5.65 gm and 50.70±2.40 gm for T1 and T2, respectively. The mean percent weight gain of tilapia was higher in T1 (1127.25±0.00) than T2 (518.51±0.00 gm). Feed conversion ratio (FCR) in T1 and T2 were 1.97±0.11 and 1.70±0.07, respectively. The specific growth rates (SGR) of tilapia in T1 4.90±3.03 and 4.78±3.83 considering the data at the beginning and the end of the production cycle, respectively. Higher total production was obtained in T1 (1070.19 gm) than T2 (610.00 gm) with 100% survival in both the treatments. The present study reveals that, the efficiency of sinking feed was higher in T1 than T2 and farmers might be suggested to practice tank-based intensive aquaculture system to get higher production in a short period of time.
