ANALISIS DEGRADASI DAN DEPRESIASI SUMBERDAYA IKAN BAWIS (Siganus canaliculatus) DI PERAIRAN KOTA BONTANG

Abstract

Bawis fish that is an endemic species and living in the seagrass biota has been found many in marine water of Bontang city. The activity of catching on this fishes has been worked by fishermen who were staying in Bontang city. Hence, if, the catching activity on this fishes without control in the entire year, it will be predicted overfishing and decreasing resources. The aim of this research was to determine the degradation rate and depreciation rate of Bawis fishes’ resources in Marine water of Bontang city. The data were collected with interview method and questionnaire to the splint and nets fishermen, and stakeholder, as well as from the capture fisheries division of DKP3 institution in Bontang city for collecting of data of time series. The results showed that Bawis fishes’ resources in Bontang city were in degradation and depreciation indicated since 2013. It has been showed by the standard coefficient value was 0.59 and 0.64 more than 0.5 in 2013, further, in 2016 increased to 0.619 and 0.68 respectively. The values of increasing were each more than 0.5, it means that Bawis fishes’ resources in Bontang city were in degradation and depreciation.

Economic Benefits and Governance of Guiding Barrier Fishing Gear in White-Spotted Spinefoot Fish Fishing Activities (Siganus canaliculatus, Park 1797) In Bontang City Waters

“…The seagrass area of Bontang City reaches 13,990.8 ha (Oktawati et al, 2018(Oktawati et al, , 2019. In this area, 112 types of fish can be found.…”

“…White-spotted spinefoot fish are endemic seagrass fish that are often found in seagrass ecosystem areas. The presence of white-spotted spinefoot fish has an important role in maintaining the stability of the seagrass ecosystem in Bontang City (Oktawati et al, 2019). White-spotted spinefoot fish are caught in seagrass areas using belat (local name) or sero fishing gear.…”

“…The high effort of fishermen to catch white-spotted spinefoot fish has an impact on ecological pressure in seagrass beds, resulting in a decline in white-spotted spinefoot fish populations (Jailani, 2006;Rohmawati et al, 2015;Wahyudin et al, 2016). Recent research conducted by Oktawati et al (2019) revealed that since 2013, white-spotted spinefoot fish resources have begun to show signs of degradation and depreciation. This research seeks to analyze the economic benefits and what policies need to be implemented to maintain white-spotted spinefoot fish resources so that they are not degraded and depreciated.…”

“…Selain itu ikan bawis juga diolah menjadi kerupuk ikan dalam industri rumah tangga. Dari sisi ekologis, keberadaan ikan baronang lingkis berperan penting dalam menjaga kestabilan ekosistem di padang lamun (Oktawati et al 2019), dan sangat berpotensi menjadi ikan budidaya ekonomis (Kordi, 2005).…”

“…Data Badan Pusat Statistik Kota Bontang menunjukkan terjadi penurunan hasil produksi tangkapan ikan baronang lingkis dari tahun 2017 hingga tahun 2020 sebesar 24,2%, yaitu dari 3.206,59 ton menjadi 2431,34 ton (BPS Kota Bontang, 2022). Selanjutnya penelitian Oktawati et al (2019) melaporkan angka koefisien degradasi dan depresiasi ikan baronang lingkis di perairan pesisir Kota Bontang lebih tinggi dari nilai kisaran koefisien toleransi yang disarankan. Data tersebut mengindikasikan telah terjadinya penurunan stok ikan baronang lingkis dari tahun ke tahun di perairan pesisir Kota Bontang.…”
