The aim of this study was to evaluate the efficiency of the biofloc system versus the recirculation system using the native Amazonian freshwater shrimp Macrobrachium amazonicum (Heller, 1862) as a cultivation organism.  In this initial evaluation, the water quality parameters of each system were measured and the survival rate in the biofloc system showed similar values for M. amazonicum grown in a super-intensive recirculation system with averages values of 60%. The results indicated that both systems were within acceptable limits in terms of parameters (physical-chemical) and the survival rate of both systems showed similar values for M. amazonicum.

High Level

Temperature is one of the most dominant water quality parameters on the survival of fish, and almost every living organism has the optimum temperature for its life. One of the obstacles in the cultivation activity is the high level of death in the most critical phase of the larvae so that the handling and carrying capacity of optimal environmental conditions can minimize the death of the larvae as well as the extreme temperature changes will also cause higher death rates of larvae. In the maintenance effort, the quality and quantity of the resulting larva becomes an important factor, as the success of production support to reach the next phase. Therefore, to find out the larval synthesis is done research about the optimum temperature with treatment temperature 240C, 260C, 280C and 300C to the survival of maintenance of botia larvae (Chromobotia macrachantus). The water quality parameters of CO2, NH3, DO, and pH are carried out at the beginning and end of the study for 28 days. The results showed that the highest survival rate at temperature treatment 240C and 260C with a value of 100%.Keywords : Botia Larvae, Temperature, Survival Rate AbstrakSuhu merupakan salah satu parameter kualitas air yang sangat dominan terhadap kelangsungan hidup ikan, dan hampir setiap organisme yang hidup didalamnya memiliki suhu optimum untuk kehidupannya. Salah satu kendala dalam kegiatan budidaya adalah tingginya tingkat kematian pada fase paling kritis yaitu larva sehingga penanganan dan daya dukung kondisi lingkungan yang optimal dapat meminimalisir kematian larva demikian pula dengan perubahan suhu yang ekstrim juga akan menyebabkan tingkat kematian larva semakin tinggi. Dalam upaya pemeliharaan, kualitas dan kuantitas larva yang dihasilkan menjadi faktor penting, sebagai penunjang keberhasilan produksi  hingga mencapai fase selanjutnya. Oleh karena itu, untuk mengetahui sintasan larva dilakukan penelitian mengenai suhu optimal dengan suhu perlakuan 240C, 260C, 280C dan 300C terhadap kelangsungan hidup pemeliharaan larva ikan botia (Chromobotia macrachantus). Parameter kualitas air yitu CO2, NH3, DO, dan pH dilakukan pada awal dan akhir penelitian yang dilakukan selama 28 hari. Hasil penelitian menunjukkan bahwa tingkat kelangsungan hidup tertinggi pada perlakuan suhu 240C dan 260C dengan nilai sebesar 100%.Kata Kunci : Larva Botia, Suhu,Tingkat Kelangsungan Hidup

This trial aimed to evaluate effects of stocking densities of 1-5 fish/m2 on growth performance, survival rate and economic efficiency of Asian seabass (Lates calcarifer) in earthen ponds. Fish with an initial length of 90.7 ± 0.1 mm and weight of 20.8 ± 0.1 g/fish and ponds with 600 m2 each and 1.5 m depth were used for this study. Experiment was designed with three treatments, including different stocking densities of 1, 3 and 5 fish/m2. The fish was fed with pellete feed containing 43 - 44% crude protein. Water quality parameters including temperature, dissolved oxygen, pH, salinity, transparency and ammonia concentration were measured once a week. Fish were sampled every 30-day intervals for length and weight measurement then for their growth estimation. Costs were recorded for economic efficiency estimation. Results showed that the water quality parameters were in suitable ranges for growth and development of Asian seabass. The final average length and weight of density 1 fish/m2 was significantly higher than those at 3 and 5 fish/m2 (P < 0.05). However, there was no significant difference on the fish growth in terms of daily length and weight gain, as well as survival rate and feed conversion ratio between different stocking densities. Asian seabass culture at 3 and 5 fish/m2 resulted in a higher profit compared to at 1 fish/m2. The highest economic efficiency in terms of area pond was showed at 5 fish/m2 treatment.

The Relationship

Water quality parameters play an important role in intensive pond ecosystems. The purpose of this study was to determine the relationship between of water quality parameters in intensive shrimp farming of L. vannamei. This research was carried out for 95 days of intensive shrimp farming in PT. Menjangan Mas Nusantara Company, Banten, with the physical, chemical, and microbiological parameters of water as the main reference object of observation. The results showed that during the shrimp culture period the pond water quality parameter concentration was considered to be quite optimal with a stable fluctuation trend, except for the salinity and TOM parameters whose values ​​were above the water quality standard. Correlation test results state that between the physical chemical parameters have a strong and heterogeneous relationship, with the strongest parameters of pH, phosphate, nitrite, and TOM. As for the microbiological variables, the correlation of physical chemistry parameters of water is considered to be very weak, because from the correlation test results, only DO parameters showed the correlation with microbiological parameters. The conclusion of this study, that during intensive shrimp culture period, the physical and chemical parameters of water have a strong correlation of association between one another and the highest are pH, phosphate, nitrite, and TOM, but only dissolved oxygen parameters that show the relationship correlation with microbiological parameters.

The research aims to determine the best stocking density in the maintenance of Siamese catfish seedlings based on the influence exerted on the survival of Siamese catfish seeds and improving water quality in the recirculation system. This research was conducted at the Green House Ciparanje FPIK Unpad Jatinangor in August 2019. Maintenance activities are carried out in a 70x70x70 cm fiber equipped with a recirculation system and filled with 150 L of water per fiber. The study was conducted with four stocking solid treatments as follows 375 fry/fiber (treatment A); 450 fry/fiber (treatment B); 525 fry/fiber (treatment C); and 600 fry/fiber (treatment D). Siamese catfish fry is 1 inch in size with an average weight of 0.307 grams. The parameters observed were the survival of Siamese catfish fry and water quality. Water quality measurements include temperature, degree of acidity (pH), and ammonia (NH3). Water quality testing was carried out at the Laboratory of Aquatic Resources, Faculty of Fisheries and Marine Sciences, Universitas Padjadjaran. During the study, there was no exchange of water or siphon. The method used in this research was analyzed descriptively and compared the results of survival rate fish and water quality parameters toward the Indonesian National Standard (SNI). The results showed that the best stocking density was 600 fry/fiber with a survival rate of 100% Siamese catfish and the ammonia value at the beginning of maintenance was 0.140 mg/L and the end of maintenance decreased to 0.137 mg/L.

The parameters inspected include SR of fish that infected; SR of fish had been treatment, Relative Percent Survival (RPS), clinical symptom and water quality. The highest survival rate percentage is treatments A4 (0.8 %) with average value 66.66 %. The best concentration of garlic extract that can heal the fish until ≥ 50 % (RPS value) from totally sample of fish were treatments A4 (0.8 %), A3 (0.6 %), and A2 (0.4 %). The clinical symptom after cure and care as long as fourteen days indicated in control (without garlic extract has been found hard damage bodies organ and the mortality fish effect, but in treatments A1 (0.2 %), A2 (0.4 %), A3 (0.6 %), and A4 (0.8 %) recover after submerged with garlic extract.
