This research aims to determine the most effective dosage of potassium diformate additives in feed to increase the body resistance of nilem carp (Osteochilus hasselti). This research used Complete Random Design (CRD) experimental method with 4 treatments and 4 replications. The treatment used was the addition of potassium diformate on feed (0 %, 0.1 %, 0.3 % and 0.5 %). After 28 days of treatment, nilem fingerlings were challenged with Aeromonas hydrophila bacteria with a density of 108 cfu ml-1. Parameters observed were the number of leukocytes, erythrocytes, survival rate, clinical symptoms and water quality. The result showed that leukocytes and erythrocytes number were significantly different in each treatment. Meanwhile, leukocytes and erythrocytes number of nilem fingerlings in challenged test were increased and decreased due to the addition of potassium diformate and A. hydrophila infection. Clinical symptoms after challenged test were relatively similar such as haemorhagic, ulceration, exopthalmia, dropsy and abnormal swimming movements. Therefore, survival rate of nilem fingerlings with 0.3 % of potassiun diformate was the highest compared to other treatments, namely 81.67 %.

Abstract. Biofloc technology in shrimp farming is a new technology that has advantages over other technologies. Biofloc technology can maintain water quality, especially ammonia and pH, suppress Vibrio growth, enhance immunity, and as natural food for shrimp. The application of this technology in shrimp farming still faces several obstacles, so not all farmers apply it. This study aims to evaluate the application of biofloc systems in white shrimp farming and formulate appropriate strategies to increase farmer productivity. The study was conducted using the survey and interview method for the perpetrators of white shrimp cultivation in Lampung Province. Collected data were strengths, weaknesses, opportunities, and threats of the application of biofloc technology in the cultivation of white shrimp. The obtained data were analyzed descriptively, while the formulation of strategies was conducted using SWOT analysis. The results showed that shrimp culture technology with biofloc technology has good prospects for increasing shrimp production. However, biofloc technology also has weaknesses that can lead to the failure of shrimp farming. The application of white shrimp biofloc technology was in quadrant I (aggressive) where this system has a good internal strength to capture existing external opportunities (SO strategy). Internal strengths include a high survival rate, relatively faster growth, environmentally friendly, able to minimize disease agents that enter the culture system, and lower feed conversion, while the opportunities they have include: shrimp prices are relatively high, there is a revitalization program unproductive ponds by the government, the issue of eco-labeling, and the growing demand for shrimp exports.Keywords: SWOT analysis, water quality, strategy, shrimp production, aggressive  Abstrak.

Abstract Water quality, chlorophyll a, phytoplankton, proto and mezo-zooplankton abundance were spatiotemporally evaluated in an estuary receiving effluents from a Pacific white shrimp Litopenaeus vannamei farm in Patos Lagoon estuary, Southern Brazil. Samples were taken before (BD) and; 1 day (1 PD) 5 days (5 PD), 10 days (10 PD), 20 days (20 PD) and 30 days (30 PD) after the effluents discharge. Some water quality parameters were affected by the effluents discharge; however, these changes were restricted to a distance of 20 m from the effluent discharge channel for a period of 5 days. The microbial community was dominated by chlorophyceae, followed by diatoms, cyanobacteria and ciliates. There was an increase in the abundance of different groups on the 1 PD sampling compared to BD. The zooplankton abundance was low in practically all sites, except for 30 PD sampling. The meso-zooplanktonic organisms were represented by copepods, mostly Acartia tonsa. Despite some effects on water quality and phytoplankton and protozooplankton abundance until 5 PD sampling, these alterations dissipated in a short period of time. We conclude that the environment quickly assimilated the effluents discharge, and the water quality parameters remained within the limits stipulated by standard guidelines.

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
