ANALISIS OF OYSTER MORPHOMETRY FROM TWO DIFFERENT LOCATIONS

Author: RIYANTO, , JAMILAH NASUTION
Abstract: Oyster is   salt-water   bivalve   molluscs  that live in  marine  or  brackish  habitats. Morphometry is the quantitative analysis of size and shape. This observation was conducted during August 2017 to September 2017 at Belawan, Medan (Site 1) and Tanjung Pura, Langkat (Site 2) . Total samples were 146 oyster or 73 oyster per location. The oysters were collected by hand picking. The oyster samples were observed at Biology Laboratory, Universitas Medan Area, North Sumatra, Indonesia. The objectives of this observation were (i) to determine how close correlation berween edible meat weight (MW) with shell length (SL=X 1 ), shell high (SH=X 2 ), shell wide(SD=X 3 ), and shell weight (SW=X 4 ), of oyster (Anadara antiquata) from two different sites, (ii) if the correlation r>0.5 it will be determined their multiple linier regression models, (iii) to determined whether or not the two multiple linier models were identik. Both locations were still in North Sumatra province of Indonesia. The distance of the two sites were around 100 km. Both sites were selected due to they were considered as central of oyster productions. The condition of both locations were relatively similar, such as climate and the salt water. The results of these observations were (i) correlation berween edible meat weight (MW ) with SL, SH, SD and SW at Belawan was r = 0.17 and at Tanjung Pura was r = 0.76 , (ii) sice the correlation r > 0.5 so, it was made the multiple regression model, and the results were Y = 0.01 X1 + 1.14 X2 + 0.45 X3 - 0.01 X4 + 4.61 at Belawan and at Tanjung Pura, it was Y = 0.96 X1 -0.56 X2 + 0.61 X3 + 0.41 X4 - 3.33. The dependent variables Y was the oyster meat weght (MW) and the independent variables were : X 1 = shell length (SL), X 2 = shell high (SH), X 3 = shell wide (SD), and X 4 = shell weight (SW). (iii) by using t-test if was defined that the two multiple linier models were identik.
