Abstract

Ikan glodok telah lama menarik perhatian para ilmuwan karena sifat amfibinya dan karena kemampuannya bertahan dalam waktu lama di luar air dan biasanya muncul selama saat air surut untuk mencari makan dan mencari pasangan. Saat ini, luas hutan Mangrove di Ekowisata Mangrove Lantebung Makassar adalah 25 Hektar yang didalamnya terdapat ikan glodok namun masih sangat kurang yang menelitinya. Penelitian ini bertujuan untuk menganalisis frekuensi kemunculan dan mengetahui persepsi masyarakat mengenai ikan glodok. Jenis penelitian ini adalah penelitian survei dengan mix methods melalui purposive sampling pada dua stasiun berbeda yang dikombinasikan dengan metode wawancara dengan panduan kuesioner. Hasil penelitian menunjukkan bahwa frekuensi kemunculan tertinggi untuk stasiun satu berada pada hari ke empat yakni sebesar 7.14%, sedangkan untuk stasiun dua berada pada hari ke tujuh yakni sebesar 10.43%. Berdasarkan pengamatan selama tujuh hari berturut-turut, frekuensi kemunculan terlihat cenderung meningkat untuk kedua stasiun. Masyarakat pesisir Lantebung tidak mengetahui nama ikan glodok, namun ikan ini dikenal dengan nama burenceng, mayoritas masyarakat tidak pernah dan tidak berniat untuk mengkonsumsi ikan ini karena menganggap ikan ini beracun meski merupakan bahan obat.

Abstract

Fixed chart fishing focuses on utilization of light aids for attract fish. Underwater submersible light ((Lacuda) LED is one of the assistive technologies that are environmentally friendly, be the subject of study in determining the characteristics of the movement or fish swimming groupings based on the operating time of the fishing gear and can be detected by hydroacoustic devices. The research method used is descriptive exploratory method by participating in fishing operations in the waters of Laikang Bay from April to September 2020. The results of the observations made at 18:00-05:00 Wita every trip shows that fish swimming activity after midnight tends to be higher than before midnight and at midnight. Based on the hydroacoustic detection of fish swimming activity in the form of solitary, medium and large groups at an average depth of 2-6 meters at 03:00-05:00 Wita. The amount of catch in hauling I is 138,4 Kg while hauling II is 157,3 Kg. The type of catch is small pelagic fish and demersal fish.

Abstract

Plankton can be grouped into two, namely phytoplankton and zooplankton. The phytoplankton group is autotrophic so that it acts as a primary producer in the waters. The research location is in Tompobulu Village, Maros Regency. Data collection was taken in June 2024. The temperature at the station based on the measurement results at the station is 28°C, pH value 7.4, total suspended solids value (TSS) 51 mg/l, do (Dissolved oxygen) value 4 mg/l. The data calculated is the index of diversity, uniformity and dominance. Overall findings of this study showed: Diversity index 1,42, uniformity 0,34 and dominance index 0,38 . Plankton sampling stations show that there are 12 species of plankton, namely: Amphora sp, Cocconeis sp, Coscinodiscus sp., Cymbella sp., Gyrosigma sp., Licmophora sp., Navicula sp., Pediastrum sp., Pinnularia sp., Surirella sp. Synedra sp.1, Synedra sp.2. It can be seen from the data above that the highest cell/liter value with a value of 1,130 is Navicula sp. The lowest value of 10 cells/liter is 4 species, namely: Pediastrum sp, Amphora sp, Coscinodiscus sp and Licmophora sp. The conclusion of the study is that the level of plankton diversity in the Tompobulu river is classified as moderate with a value of 1.42, the most abundant species is Navicula sp with a total of 1130 cells/liter. The water condition that affects and does not meet the quality standards is TSS. This parameter is also what affects the condition of the plankton.
