Abstract

The research was carried out to investigate the best amount of large freshwater snail (Filopaludina javanica) meat as feed for the growth and survivals (SR) of freshwater lobster C. quadricarinatus.  The size of freshwater lobster used in this study was 1.70 – 23.90 gr.  Lobsters were kept in aquariums measuring 30 x 30 x 40 cm for 30 days. The experimental design used was a completely randomized design (CRD) with three treatments and three replications that is A (4%), B (7%) and C (10%) of feed. Data analysis was used linier regression. The results showed the (R2) marks close to 1 means that the time of experiment effects the growth of lobster in all treatments, 4% feed (R2 =0,8919), 7% (R2=0,9942) and 10%(R2=0,9484, where the highest coefficient regression was treatment B (0,5818) followed by treatment A (0,4625) and C (0,42), respectively.  The highest survival rate was found in treatment B (91.7%), treatment A (75%) and C (66.7%), respectively.  Results of analysis showed that the size and the length of time of experiment effects the time of growth and survival.

Abstract

This study aims to determine the adequacy of feed because of fish waste and tofu leftover flour for the development of saline tilapia, feed efficiency, feed conversion ratio, and survival rate. This examination was directed at the Laboratorium Technology Aquaculture. The quantity of fish taken was 300 tilapia fish with a size of 5–6 cm and a typical load of 5 grams. The test feed to be utilized in this review was formed from different fundamental fixings utilized, then, at that point, added with fish waste and tofu squander. In light of the consequences of the examination of the impact of various feed equations, specifically fish waste and tofu leftovers, they significantly affect the growth of saline tilapia. Different feed recipes influence the development of saline tilapia. From the consequences of exploration on saline tilapia, freshwater fish can inhabit a saltiness of 20 ppt in a controlled holder in one month or less. Of all the development boundaries estimated in this review, feed 3 was the best contrasted with different feeds. The aftereffects of the investigation of the change showed that the feed detailing was unique to that of fish waste and tofu residue, and the impact was exceptionally huge. Keywords: tilapia, growing, feed efficiency, feed conversion, survival

Abstract

This study aims to determine fluctuations in water quality parameters and flock development in tilapia (Oreochromis niloticus) aquaculture using the biofloc system. The water quality parameters studied were temperature, DO (Dissolved Oxygen), pH, ammonia (NH4), nitrite (NO2), and nitrate (NO3). The research was carried out at the Freshwater Aquaculture Fisheries Center (BPBAT) Tatelu, from May 2023 to June 2023, using the case study method. The average temperature during the study was 27.2oC, DO (5.05 mg/L) and pH (5.40). The average NH4 value was 0.58 mg/L. The results of this study indicated that ammonia began to increase from the first day and reached a peak on day 5 with a value of 0.77 mg/L. The average NO2 value was 1.12 mg/L, The results of this study indicated that the increase in NO2 occurred rapidly from day 5 and reached a peak on day 27 with a value of 1.92 mg/L, then began to decline. The average NO3 value was 25.21 mg/L, the NO3 value increased on the 12th day to a value of 35.1 mg/L, and this value began to stabilize even though there was a little pressure. The highest floc density was on the 34th day with a value of 34 ml/L, the lowest was on the 11th day with a value of 4 ml/L and the average floc density was 23 ml/L. Tilapia culture in the biofloc system had an absolute growth of 57.11 grams, a specific growth ratio of 1.5%, feed conversion (FCR) of 1.2, and survival of 97%. Keywords: Fish cultivation, Oreochromis niloticus, biofloc system
