Abstract

The growth of catfish could be improved if the utilization of feed protein by fish can be more efficient. Bromelain is an enzyme of proteases that able to hydrolyze proteins into simpler compounds to be more easily absorbed and utilized of the proteins body. The purpose of the research was to observe the effects of bromelain on protein utility rate and growth of the African catfish (C. gariepinus). The variables measured were feeding efficiency (FE) value, protein efficiency ratio (PER), relative growth rate (RGR), and survival rate (SR). This research used completely randomized design (CRC) with 4 treatments and 3 replicates, i.e. treatment A (did not use bromelin), B (0.75% bromelain), C (1.5% bromelain), and D (2.25% bromelain). The results showed that the influence of the use of bromelin in feed on feeding eficiency (FE), PER, and RGR values were significant (P0.05) on survival rate. Based on the results of treatment A, B, C, and D, it can be concluded that the use of bromelin in feed for C. gariepinus produced better EPP, PER, and RGR values than the feed with no bromelain.

Abstract

Tilapia (Oreochromis niloticus) is a freshwater fish which have important economic value, easy to cultivate, good taste, inexpensive and have higher tolerance in different enviroment. Increased density until maximum carrying capacity will decrease growth of fish. The incrase in density will be followed by an increase in the amount of feed, wasted metabolism, oxygen consumption and can decrease water quality. Decline in water quality will result in slow growth and mortality. The purpose of this research was to explore the influence of different density and the best quantity for survival rate and growth of Tilapia (O. niloticus) in resirculation system with Zeolit filter and knowning the effetiveness of zeolite filter on resirculation system. This research used different density of Tilapia (O. niloticus ) size 4-6 cm. Eksperimental reserch conducted use. RAL (completely randomize design) with 3 treatmens and 3 replication. Treatment A (10 density of fish), Treatment B (15 density of fish) and Treatment C (20 density of fish). Data obtaired are to absolute long growth, rate of absolute specifics length, find ammonia levels, survival rate, feeding efficiency, and water quality parameters. The result showed that different density has significant effect towards the growth Tilapia but not for survival rate. The survival rate for each treatment was A = 86,67±5,77 %, B = 84,44±3,85 %, and C = 78,33±2,89 %. Rate of absolute specifics length in Tilapia at the highest treatment was A = 3,53±0,06 cm, and C = 2,57±0,06 cm. The average of specific growth rate on Tilapia was A treatment with highest of 2,45 0,07%/day, and the lowest is reatment C = 1,76 ±0,05%/day. The effectiveness of the treatment of a zeolite filter can word to the limit of the study. Compared with treatment B and C, which only reached day 20.
