Utilization of Ex Tin Mine Lake For Aquaculture: Case Study Of Muntok Sub District, West Bangka Regency

Abstract

Tin mining has left hundreds of ex-mine lake in Muntok Subdistrict, West Bangka Regency, which is both problems and potential to be exploited. Empowerment of the lake for freshwater fish farming can provide alternative livelihood opportunities besides tin mining. The study of the use of the lakes for fish farming aims to determine the purpose of fish farming with its problems and potential. The study was conducted in June - July 2018 with a descriptive qualitative method through a process of interviews and observations during the implementation of the task of fisheries instructor. The object is on three groups who use the lake for fish farming. The lake can be used productively for catfish and catfish culture utilizing the system of the pen culture. The obstacle of using the lake for fish culture is the potential for bioaccumulation of heavy metals, the difficulty of implementing water quality management, and lower productivity compared to artificial ponds. Under cultivation is recommended to choose Clarias commodities in consideration of consumer safety against bioaccumulation of heavy metals.

Assessment of water quality of the ex-sand mining sites in Pasir Sakti District East Lampung for tilapia (Oreochromis niloticus) culture

“…While a proper pH for fish growth ranged from 6.5-9.0 with an optimal range of 7.5-8.7 (Kordi and Tancung, 2010). Acording to Kurniawan (2012) and Triswiyana et al (2019), optimal range of pH for tilapia culture are 6.5 -8.0.…”

Pendampingan Budidaya Ikan Lele Menggunakan Teknologi Bioflok dengan Pakan Berprobiotik di Desa Balunijuk Kabupaten Bangka

“…Kolong adalah sebuah kolam yang terbentuk dari penambangan bijih timah di Bangka Belitung. Kendala pemanfaatan kolong Bangka Barat untuk budidaya ikan adalah potensi bioakumulasi logam berat, sulitnya penerapan pengelolaan kualitas air, dan produktivitas yang lebih rendah dibandingkan kolong buatan (Triswiyana et al, 2019).…”

Pola Pertumbuhan Ikan Nila (Orechromis Niloticus) pada Keramba Jaring Tancap Kolam Tanah dengan Pemberian Pakan berupa Pellet di Desa Balunijuk, Bangka Belitung

“…Kolong merupakan kolam yang terbentuk akibat dari galian penambangan bijih timah di Bangka Belitung. Kendala pemanfaatan kolong di Bangka Barat untuk budidaya ikan adalah potensi bioakumulasi logam berat, sulitnya menerapkan manajemen kualitas air, dan produktifitasnya yang lebih rendah dibandingkan kolam buatan (Triswiyana et al, 2019). Namun demikian, kualitas air di kolam buatan mungkin lebih baik sehingga dapat memacu produktifitas ikan peliharaan.…”
