PENGARUH PERBEDAAN JENIS PAKAN TERHADAP PERTUMBUHAN LOBSTER LAUT, PANULIRUS VERSICOLOR
ABSTRACT: The aim of the
research was to find out the growth rate of the marine lobster, Panulirus
versicolor, fed different types of diets.
The experiment was conducted at the Laboratory of Aquaculture
Technology, Faculty of Fisheries and Marine Sciences, Sam Ratulangi
University. The experiment was set
up in 3 treatments, which were three
different types of diet: treatment-A: papaya leaves, treatment-B: coconut
flesh, treatment-C: skipjack-fish flesh.
Each treatment was triplicated.
The tested lobsters were collected from the marine waters of the
Likupang village, North Minahasa Regency.
The tested lobsters were weighed at the beginning, at the end of the experiment, and at the interval
of 14 days during the experiment period. The data of the body weight change
were statistically analysed using the analysis of the homogeneity of the 3
different linear regression coefficients, between time (X) and the body weight
of the lobsters (Y) fed different types of feed, at the confidence test level a
= 5% and 1%. The results show that the
body weight of the tested lobsters fed skipjack-fish flesh increased 4 grams
after 30 days of the rearing period. The
body weight of the tested lobsters fed papaya leaves decreased 11 g, and the
body weight of those fed coconut flesh decreased 3 g after 30 days of the
rearing period. The result of the
regression analysis shows, the assumption that the 3 regression coefficients
are homogenous is rejected. In other
words, there is a significant difference among the growth rates of the tested
lobsters fed different type of diets.
Compared to skipjack-fish flesh, the papaya leaves and coconut flesh
significantly slow down the level of the water quality degradation during
experiment period.
