PROTECTED, PROHIBITED, AND INVASIVE FISH DIVERSITY AND DISTRIBUTION IN RANAU LAKE OF WEST LAMPUNG DISTRICT
ABSTRACT: The objectives of
this research were to collect fish species in Ranau Lake of West Lampung
District, analyze the fish community structure, determine the types of fish
that are protected, prohibited, or invasive and mapping its distribution.
Sampling was done on three locations: Station 1 (Suka Banjar), Station 2
(Kagungan), and Station 3 (Lombok). The data were analyzed by the structure of
the community: diversity (H'), uniformity (E) and dominance index (C). The
result of the identification indicate that there are 26 species of fish and
total number of fish is 184. The results of the analysis of fish community
structure in Ranau Lake have medium diversity, medium distribution and moderate
community stability (H’=1.43), medium uniformity and volatile communities (E =
0.41), low dominance and no dominant
fish species (C = 0.32). From the 26 fish species in Ranau Lake, there are no
protected and prohibited fish species, there are two types of fish categories
as invasive alien species: nile tilapia (Oreochromis niloticus) and suckermouth
catfish (Hypostomus plecostomus).
