Abstract

Fishing activity in Malahayu Reservoir has been done since long time. Unlimited fishing may impact to the decresing of fish resources of those waters. This study presents an assessment of fishing practices in Malahayu reservoir between 2008-2016 periods. Data of potential fish production and catch per unit effort were estimated by using different estimate models, catch per unit effort was analyzed annually, while potential fish production was analyzed by using five models namely model by Henderson & Welcome (1974), Teows & Griffith (1979), Marshal (1984), Moreau & De Silva (1991) and Crul (1992). The results show that changes of fish composition has accured, which was originally dominated by native fish while for now it is dominated by 72,05% of tilapia (Oreochromis niloticus) as an introduced fish. Furthermore, the average catch per unit effort (CPUE) in Malahayu reservoir is about 11,82 kg / fisherman, while the average potential production is about 198,55 kg / year. CPUE value and potential production indicate that exploitation rate in Malahayu Reservoir are in fully-exploited or perhaps over-exploited condition. Related to those conditions, not to increase the number of efforts (fishermen) as a management option towards sustainable fisheries.

Abstract

Produksi nasional kepiting bakau yang terus menurun serta semakin sulitnya nelayan menangkap kepiting bakau di habitat aslinya, menjadi indikator terjadinya ancaman keberlanjutan sumberdaya di alam. Kepiting bakau (Scylla serrata) merupakan salah satu komoditas perikanan penting propinsi Kalimantan Timur, yang sebagian besar berasal dari hasil tangkapan nelayan di sekitar perairan Delta Mahakam. Informasi status stok kepiting bakau di Estuari Mahakam belum tersedia sehingga menjadi kendala dalam menyusun kebijakan pengelolaan sumberdaya kepiting bakau pada skala daerah dan nasional. Penelitian ini dimaksudkan untuk mengetahui status stok kepiting bakau di Estuari Mahakam dengan menggunakan metode rasio potensi pemijahan induk berbasis data panjang (Length-Based Spawning Potential ratio/SPR), dalam kurun waktu 5 bulan, yaitu November 2016-Maret 2017. Hasil analisis menunjukkan bahwa nilai SPR saat ini (actual estimate) diperoleh sebesar 0,43 atau sebesar 43% sehingga dikategorikan sebagai fully-moderate exploited karena masih berada di atas ambang batas yang telah ditetapkan sebesar 30%. Nilai SPR 43% mengindikasikan bahwa masih terdapat biomassa kepiting bakau dewasa sebesar 43% di alam, untuk menunjang keberlanjutan rekruitmen. Di samping itu, laju penangkapan (F) terhadap mortalitas alami (M) yang mencapai 0,86 menunjukan bahwa kematian alami lebih mendominasi dibandingkan tekanan penangkapan.The decreasing in national production of mangrove crab and the difficulties for fishermen to catch mangrove crab in its natural habitat, become an indicator of the threatened of those resources in nature. Mangrove Crab (Scylla serrata) is one of the important fishery commodities of East Kalimantan province, mostly caught around the waters of Mahakam Estuary. Meanwhile, information concerning the stock status of mangrove crab in Mahakam Estuary is not yet available so it becomes an obstacle in formulating policies related to the management of mangrove crab resources at the regional and national scale. This research is intended to know the stock status of mangrove crab (Scylla serrata) in Mahakam Estuary by using Length-Based Spawning Potential ratio (SPR). The result of analysis show that the value of the current SPR (actual estimate) is 0,43 or 43%, it is categorized as fully-moderate exploited because it is still above the predefined threshold of 30%. The SPR value indicates about 43% of mature crabs biomass are still available to support the sustainability of recruitment. Nevertheless, the rate of capture (F) on natural mortality (M) has reached 0,86 which is mean that fishing exploitation has contributed 86% to the mortality of mangrove crab in its habitat.

Abstract

Era Society 5.0 merupakan kelanjutan dari era Industry 4.0. Indonesia, khususnya sub bidang perikanan budidaya dituntut untuk melakukan berbagai upaya dalam menyambut dan menghadapi perkembangan masyarakat dunia. Berbasis teknologi budidaya yang sudah dikembangkan saat ini dan kesiapan Sumber Daya Manusia yang menerapkan teknologi tersebut diharapkan tercipta kondisi yang dapat mendorong pemanfaatan sumber daya kelautan dan perikanan secara berkelanjutan sehingga tercapai kesejahteraan bangsa melalui masyarakat pembudidaya 5.0. Kajian ini menggunakan data sekunder yang berasal dari berbagai sumber atau literatur. Data kemudian dianalisis secara mendalam menggunakan model rasional yaitu analisis secara logis dan step-by-step. Kajian menghasilkan berbagai hal yang perlu mendapat perhatian untuk menuju perikanan budidaya yang berkelanjutan adalah mempersiapkan konsep masyarakat pembudidaya 5.0 secara nasional, mengatasi persoalan yang dihadapi dalam tingkat produktivitas dan efisiensi, melakukan persiapan tindakan untuk mendukung terciptanya masyarakat pembudidaya 5.0, dan inisiatif yang dapat dilakukan dalam industri budidaya ikan.The Society 5.0 era is a continuation of the Industry 4.0 era. Indonesia, especially the aquaculture sub-sector, must make various efforts to welcome and face the development of the world community. Based on aquaculture technology that has been developed at this time and the readiness of human resources to apply this technology, it is hoped that conditions will be created that can encourage the sustainable use of marine and fisheries resources so that the welfare of the nation can be achieved through the aquaculture-community 5.0. Secondary data from various sources or literature is used in this study. The data were thoroughly examined using a rational model, specifically a logical and step-by-step analysis. The study resulted in various things that need attention to achieve sustainable aquaculture, namely preparing the concept of a 5.0 community nationally, overcoming the problems faced in the level of productivity and efficiency, preparing to support the creation of an aquaculture-community 5.0, and initiatives that can be taken in the aquaculture industry.
