Abstract

The objective of this research was to determine the species composition and abundance of fishes in the waters of Tontayuo Village and Lamu Village, Batudaa Pantai Subdistrict, Gorontalo Regency. This research was conducted from April to May 2022. The data collection of this research was carried out using a net with a length of 50 m, a widh of 2 m, and a mesh size of 1.5 cm drawn in the seagrass meadow, and it was replicated three times at each station, namely station I (Tontayuo Village) and station 2 (Lamu Village). The findings denoted that the highest species composition was found at station I with 34 species, while at station 2, there ware only 11 species. At the same time, the highest abundance value found at station 1 was Piotosus lineatus species, and the highest abudance at station II was Caranx melampyus species. Overall, the finding signified that the composition and abundance of fishes at station I and station II ware highly different due to the different water condition and fishing times.

Abstract

Blue Marlin Beach has been functioned as the marine tourism attraction by the local government of Gorontalo regent due to the beauty of the underwater. However the natural resources in the Blue Marli Beach have not been docuented, specifically for macroalgae. Therefore, this research aims to provide the data and information about species composition of the green macroalgae in the Blue Marlin Becah. This research was conducted for two months starting from November to December 2020. The measurement of GPS coordinate, seawater current, temperature, and wave actiion was concucted with Fishing Points Software. Observatory methode was performed in this study to collect the specimens. Then, all specimens was put-in the zipperbag and stored in the coolbox containing with the ice to protect the specimens in fresh. The results show that there are 6 species of the green macroalgae. Theya are Bornetella sphaerica, Caulerpa sertularioides, Valonia aegagropila, Boergesenia forbesii, Acetabularia caliculus, and Chaetomorpha crassa. The average of sea water temperatur during the study is 31°C with the seawater current is 0.1 m/s and wave is 0.2 m
