Abstract:
Cantang grouper (Epinephelus fuscogutattus lanceolatus) is one of the most important
economical fish species but it's growth is slower than other fish. The addition of enzymes to
artifical feed is done to maximize the protein for fish growth. Papain enzymes are exogenus
enzymes that aid in the process of protein hydrolysis. This research aims to determine the effect
of papain crude enzyme extract (PCEE) on daily growth rate, feed efficiency, number and length
of villy. This research was conducted on June - November 2017 at floating net cage Pangandaran
Coastal- West Java. The test fish used is cantang grouper with average weight of each 15 gr and
length of 7 - 8 cm as much as 900 fishes. The research method used was Completely
Randomized Design (CRD) consisting of 5 treatments: A (5% PCEE), B (3,75% PCEE), C
(2,5% PCEE), D (1,25% PCEE) and E (without PCEE) with 3 replications. The data analysis
with F test is followed by Duncan multiple range test. The results of this research show that the 5
% PCEE can increasing the daily growth rate (3.16 %), feed efficiency ( 71.56 % ), number of
villy (53 pieces) and length of villy 523 mm. |
