Comet fish is one type of ornamental fish that has been widely cultivated because it has an attractive body shape and color. The main obstacle in the development of comet fish farming is the limited number of seeds, both in quality and quantity. Egg quality is a major factor in the success of fish hatcheries. According to Andriyanto et al, (2013) quality eggs have a high level of fertilization and hatching (high fertility and hatching rate). Putri et al. (2013) stated that water quality factors, especially temperature, were very important factors in the life of the organism. The study was conducted for 1 month which was implemented April to May 2018. The place of research was carried out at the UPR (Rakyak hatchery unit). big. environmental design Completely Randomized Design (CRD) with 4 (four) treatments and 3 (three) replications, each treatment is: Treatment A: Temperature 26 oC + Eggs 100 grains, Treatment B: Temperature 28oC + Eggs 100 grains, Treatment C: Temperature 30 oC + Egg 100 grains, Treatment D: Temperature 32oC + Eggs 100 grains.

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.

Stocking density is an important factor in cultivation, it can save land use, and increase the efficiency of fish farming. The purpose of this research was to determine the different density information on tilapia seeds measuring 2-3 cm as an alternative to using tilapia (O. niloticus) seeds 7-9 cm in size so that they can be developed in Batur Lake. The research was conducted in January - March 2020 in the floating net cages in Trunyan Kintamani village, Bangli, Bali. The research used a completely randomized design method with three treatments and three repetitions. The Tilapia seeds used are 2-3 cm with different stocking densities, 100 ind/m3, 150 ind/m3, and 200 ind/m3. The parameters observed were SGR (Specific Growth Rate), absolute growth, SR (Survival Rate), FCR (Feed Conversion Ratio), and water quality including temperature, DO, pH, TDS. The results of this study indicated that stocking density did not have a significant effect on the growth and survival rate of tilapia seeds, because the temperature was too cold so that the tilapia seeds failed to adapt properly at the beginning of stocking and the physiological conditions of the fish were disturbed so that the fish experienced stress and went to died. Water quality parameters measured include temperature with a range value of 25.86-25.880C, pH with a range value of 9.08-9.13, DO (Dissolved oxygen) with a range value of 7.9-8 mg/L, and TDS (Dissolved solids) with a range value of 1040.25-1041.58 mg/L.

AbstrakIkan nila (Oreochromis niloticus) merupakan suatu komoditas perikanan air tawar yang bernilai ekonomis. Permasalahan yang saat ini dihadapi dalam budidaya ikan nila adalah harga bahan pakan terutama tepung ikan semakin mahal. Upaya yang dapat dilakukan adalah menggantikan tepung ikan dengan limbah padat surimi ikan swanggi (Priacanthus macracanthus) secara kimiawi. Penelitian yang dilakukan bertujuan untuk mengetahui pengaruh substitusi limbah padat surimi ikan swanggi (Priaacanthus macracanthus) secara kimiawi pada tepung ikan terhadap laju pertumbuhan dan efisiensi pakan ikan nila (Oreochromis niloticus). Penelitian ini menggunakan metode eksperimental dengan Rancangan Acak Lengkap (RAL). Analisa statistik menggunakan Analysis of Variant (ANOVA) supaya dapat mengetahui pengaruh perlakuan. Berdasarkan hasil penelitian didapatkan hasil bahwa substitusi limbah padat dari surimi ikan swanggi (Priacanthus macracanthus) secara kimia pada tepung ikan tidak berbeda nyata (p>0,05) terhadap retensi protein dengan nilai P0(7,97), P1(9,26), P2(7,07), P3(11,02) dan retensi lemak ikan nila (Oreochromis niloticus) P0(4,09), P1(5,67), P2 (4,53), P3 (6,73) tidak menunjukkan perbedaan yang signifikan (P>0,05). Kualitas air media pemeliharaan ikan nila adalah suhu 26-28 °C, Oksigen terlarut 5-8 mg/l, pH 7-8, Amonia 0-1,5 mg/l. Abstract Tilapia (Oreochromis niloticus) is a freshwater fishery commodities that have economic value. The problems currently faced in tilapia fish farming is the price of feed ingredients, especially the more expensive fish meal. Efforts to do is replace fish meal with fish surimi swanggi solid waste (Priaacanthus macracanthus) chemically. This study aimed to determine the effect of substitution of solid waste swanggi fish surimi (Priaacanthus macracanthus) chemically in fish meal on the rate of growth and feed efficiency of tilapia (Oreochromis niloticus). This study uses an experimental method with completely randomized design (CRD). Statistical analysis using the Analysis of Variant (ANOVA) to determine the effect of treatment. Based on the results of the study showed that the substitution of solid waste swanggi fish surimi (Priacanthus macracanthus) chemical in fish meal did not significantly difference (p> 0.05) on the protein fish meal in the value of P0(7,97), P1(9,26), P3(7,07), P3(11,02)and retention fat tilapia (Oreochromis niloticus) P0(4,09), P1(5,67), P2 (4,53), P3 (6,73) did not showed significantly difference (P>0.05). Maintenance of water quality media tilapia is 26-28 ° C temperature, dissolved oxygen 5-8 mg / l, pH 7-8, Ammonia 0-1.5 mg / l.
