Abstract

Papua’s freshwater ecosystems in the western part of New Guinea have begun to record widespread introductions of invasive species over the past decade. This lake's most dominant and common exotic species is Amphilophus labiatus (Günther, 1864). A study was conducted to document the length-weight relationship and condition factor of these fish in Lake Sentani. From June to August 2019, fish were caught using floating gillnets at six locations around the lake. Total length (TL) (mm), body depth (mm), and body weight (grams) were measured, and condition factor based on gender, body weight, and body length were observed in 345 fish, including 264 males and 81 males. The growth pattern of A. labiatus is positively allometric, with b values ranging from 3.19 to 3. 20 and coefficients of determination (r2) ranging from 0.84 to 0.87. Although the average body length of A. labiatus males was shorter than females, condition factor (CF) values were not significantly different between the sexes and ranged from 0. 64 to 2.03 (0.97 ± 1.17, mean ± SD). For males, it went from 0.67 to 1.19 (0.94 ± 0.13 mean ± SD). However, monthly CF data show a significant decrease in CF in August, suggesting that spawning events occur in late July or early August. A. labiatus grows well and colonizes habitats throughout Lake Sentani.

Abstract

Keakwa village is located in the coastal mangrove forest area in East Central Mimika District with an area of 9,052.5 ha. The Keakwa mangrove forest is a mangrove forest that grows abundantly to protect coastlines and residential areas. The Mollusk Group in Keakwa has the potential as a source of protein and economic and cultural value for the community. through Lectures and Focus Group Discussion activities for the Keakwa community, activities carried out for 2 weeks in 2022. utilizing mollusks around Keakwa waters. These conditions can be developed as ecotourism potential. This service aims to understand and get to know molluscs and their use and prospects as a source of community economy in Keakwa, Timika, strategies for developing and utilizing molluscs in ecotourism development, by conducting lectures, from the results of evaluating knowledge about the benefits and potential of local resources, especially molluscs, after Community outreach is carried out to understand the benefits and potential of local resources. With the hope of supporting the development and management initiatives of the Keakwa community in the field of ecotourism development, in supporting the economy of the Keakwa  community.
