IDENTIFIKASI GASTROPODA DI SUB DAS ANAK SUNGAI GANDONG DESA KERIK TAKERAN
Abstract: The aim of research
to determine the diversity and Gastropod that predominate in sub watershed
tributary village Gandong Takeran Kerik. Descriptive qualitative research
method with type of observational study. Determination and site selection
studies using transect sampling method, the size of 1x1 m transect quadrant.
Research station at 3 stations with 3 points each station. The data was
analyzed after identifying the calculation dominance index and diversity index.
Gastropod identification results found 4 genera Thiara, Melanoides, Brotia, and
Clea. The highest abundance of gastropods at station II, namely 13.7 ind/m2.
Thiara highest dominance index is 0.654, indicating that Thiara mendominansi in
sub watershed tributary village Gandong Takeran Kerik. Diversity index of each
station 0.617, 0.765, and 0.615, indicating that the diversity of gastropods in
sub watershed tributary village Gandong Takeran Kerik is very low.
Environmental parameters air temperature 30C - 31C, 28C - 29C water
temperature, pH 7 to 7.3, and dissolved oxygen (DO) 5mg /l - 5,4mg /l.
