Abstract

Lake Sentani is the biggest lowland lake in Papua and the biggest freshwater fish source in Jayapura. The lake has highest endemism and one of freshwater ecosystem conservation priorities in Papua. Lake organisms consist of water plants, mollusks, crustacea and fish. In Lake Sentani, there are 19 species of fish including endemic, native and anadromous and introduced species. This program aims to deliver knowledge on fish species of Lake Sentani and fish species grouping for elementary school students, grade IV to VI of SD Negeri 5 Puay, Puay Village, East Sentani District, Jayapura. Methods used were seminar, training and practice of fish species grouping, drawing a fish and writing its story. Moreover, pre test and post test consist of questions about Lake Sentani fish and its grouping was deliver to measure the level of knowledge of the students before and after the program. Level of knowledge of students on fish of Lake Sentani was evaluated based on the results of pre test and post test. Student knowledge on Lake Sentani fish species were increasing which show by pre test and post test results. Twelve out of 13 (92%) students showed their post test results were increasing and only one student’s test result was decreasing. Eventhough there are more students with good post test result than those who do not, the level of knowledge on Lake Sentani’s fish and its grouping is not fairly distributed among the students. It is shown by the fact that there are 62% or 8 students  that doing poorly on this test. Therefore, various programmes with various teaching methods for students should be desigend to increase knowledge of students on fish species and its grouping in Lake Sentani. Keywords: fish, fish grouping, Lake Sentani, Puay, students

Abstract

Freshwater community in Lake Sentani comprise of 35 species including three endemic species, seven native species, eight anadromous fish and 17 introduced species. Two native species are Sentani Gudgeon (Oxyeleotris heterodon) and Snakehead Gudgeon (Giuris margaritacea). The survey aims to document the ecology and fish abundance of the gudgeons in Lake Sentani. Fish sampling was done passively by using gill nets with three different mesh sizes in five locations; Puai, Enandowai, Waena, Ayapo and Yahim. Substrate type, water vegetations, habitat depth and fish abundance were recorded each locations. Substrate preferences of the gudgeons are sand, mud and gravel, while O. heterodon was more abundance in sand mud substrate type. Moreover, water vegetation preference was different between O. heterodon and G. margaritacea. Sentani Gudgeon prefer habitat with dense water vegetations, while G. margaritaceus could be found in habitat with or without water vegetation. Theses two gudgeons were found in relatively the same habitat depth, up to 7 meters depth. O. heterodon and G. margaritacea had a very low abundance in the lake. It is important to conserve lake area from the edge  up to 7 meter depth that consist of sand, mud and gravel substrate types and dense water vegetation to ensure the population of these two gudgeons are abundance in Lake Sentani.   Key words: Ecology, Lake Sentani, relative abundance, O. heterodon, G. margaritacea.
