PENGELOLAAN PERIKANAN DI DANAU LIMBOTO PASCA PENGERUKAN

Abstract

Danau Limboto di Propinsi Gorontalo termasuk danau kritis yang disebabkan karena sedimentasi/pendangkalan, eutrofikasi dan gulma air eceng gondok. Pada 2013 di Danau Limboto telah dilakukan program pengerukan dan tanah hasil pengerukan dijadikan tanggul penahan air mengelilingi danau. Tulisan ini bertujuan untuk mendapatkan pola pengelolaan perairan Danau Limboto pasca pengerukan. Penelitian perikanan di Danau Limboto telah dilakukan sebelum pengerukan sejak tahun 2006 – 2010 dan sesudah pengerukan pada periode 2014 – 2016. Pelaksanan pengerukan dan pembuatan tanggul di Danau Limboto menyebabkan terjadi perubahan ekologis yang penting yaitu; pendalaman air, tanggul penahan air, habitat lumpur yang terangkat ke atas dan tertutupnya wilayah ruaya ikan yang bermigrasi.Limboto Lake in Gorontalo Province belongs a critical lake caused by sedimentation, eutrophication and water hyacinth ). The dredging program had been initiated at Limboto lake since 2013 and dredged soil has been used as water-retaining embankments around the lake. This paper aim was to derive the management pattern of Limboto lake waters after dredging. Fisheries research was conducted at Limboto lake during before dredging during 2006 - 2010 and after dredging program. During 2014 – 2016. Implementation of dredging and embankment construction in Limboto Lake , hence has caused an important ecological changes that is; Water depths, water retention embankment, uplifted mud habitat and the closure of migratory fish beeding areas.
