“…In New Zealand (New Zealand National Rock Lobster Management Group 2013) and Western Australia (Caputi et al 2015), fleet sizes did greatly reduce as quotas were reduced and catch rates rose substantially, implying that gains in economic yield from lower exploitation rate will be greater than estimated here.…”

“…Formally targeting MEY (http://www.afma.gov.au/about-us/functionsand-powers/) has affected management decision making in many Australian Commonwealth fisheries such as the northern prawn fishery (Dichmont et al 2010), usually leading to substantial decreases in exploitation rate. A target of MEY has also been pursued in Australian state government jurisdictions, including in Australia's most valuable single species fishery, that for western rock lobster (Panulirus cygnus) (Reid et al 2013;Caputi et al 2015).…”

“…Lobster fisheries in New Zealand (Haist et al 2013) have applied formal decision rules, and New South Wales (Montgomery and Liggins 2013) has adopted an independent quota-setting committee, providing examples of quota-setting regimes that achieved much higher lobster catch rates leading to large improvements in both economic performance and sustainability indicators. Catch rates of Western Australian lobster have also increased greatly (de Lestang et al 2012) due to large reductions in yearly effort and fishing capacity, which reduced costs substantially, leading to substantial increases in net economic yield (Reid et al 2013;Caputi et al 2015).…”

To advance economic and sustainability objectives in a lobster fishery, four broadly different management policies were evaluated: minimum and maximum size limits, constant catch quotas, and quota set yearly in proportion to the previous year's catch per unit effort (CPUE). The performance of each policy was evaluated based on its discounted economic yield, together with egg production, catch, and catch stability. Maximum size limits performed poorly for all indicators. Raising the minimum size increased economic yield by improving yield-per-recruit. Output controls, both constant and dynamic, uniformly outperformed size limits, leading to substantially higher economic yield and egg production. A dynamic harvest control rule, setting quota in proportion to the previous year's catch rate, achieved the highest economic yield, catch, and egg production over 20 years. The optimal (30%) exploitation rate under this policy produced a 182% improvement in economic yield compared with a baseline strategy of only minimum size, but led to a mean year-to-year change in quota of 11.5% in response to yearly variable recruitment. This quota-setting management regime is straightforward to implement, using only catch rate as input. When absolute exploitation rate estimates are not available, this quota-setting harvest control rule can be constructed using only a target level of effort.Résumé : Pour favoriser l'atteinte d'objectifs économiques et de durabilité dans une pêche au homard, quatre politiques de gestion généralement distinctes ont été évaluées, à savoir les limites de taille minimum et maximum, des quotas de prises constants et l'établissement annuel des quotas en fonction des les captures par unité d'effort (CPUE) de l'année précédente. La performance de chacune de ces politiques a été évaluée sur la base de son rendement économique actualisé, combiné à la production d'oeufs, aux prises et à la stabilité des prises. La performance de limites de taille maximum est faible pour tous les indicateurs. En améliorant le rendement par recrue, l'augmentation de la taille minimum s'est traduite par une augmentation du rendement économique. La restriction, dynamique ou constante, des prises a uniformément donné de meilleurs résultats que les limites de taille, produisant un rendement économique et une production d'oeufs sensiblement plus importants. Une restriction dynamique des prises, soit l'établissement de quotas en proportion du taux de prise de l'année précédente, a donné le rendement économique, les prises et la production d'oeufs les plus élevés sur 20 ans. Le taux d'exploitation optimal (30 %) en vertu de cette politique a produit une amélioration de 182 % du rendement économique par rapport à une stratégie de référence basée sur la seule taille minimum, mais a mené à une variation interannuelle moyenne des quotas de 11,5 % en réponse aux variations interannuelles du recrutement. Ce régime de gestion basé sur l'établissement de quotas est simple à appliquer, ne nécessitant que le taux de prise comme intrant. Quand des es...

“…Lobsters have become a commodity that is partly available from the natural catch product, while lobster culture has not yet been performed well in Indonesia, even in other countries (Prompatanapaka dan Lopetcharat, 2020; Goodman et al, 2021). The regulation of lobster culture business needs more attention to produce sustainable lobster, following the market demand (Nursan et al, 2021) and social aspects (Turner et al, 2014;Caputi et al, 2015). Lampung Province, specifically in the Pesisir Barat area, has abundant lobster seeds (puerulus), known as the lobster catching area, which the fishermen utilize as the main income source.…”

Indonesia merupakan salah satu negara yang melakukan ekspor lobster ke negara Hongkong, Vietnam, China, dan Singapura, dengan nilai ekspor lobster Indonesia mengalami rata-rata pertumbuhan 3,54% pertahun. Produksi lobster tersebut masih mengandalkan hasil tangkapan, karena budidaya lobster belum banyak dilakukan di Indonesia. Pantai Barat Provinsi Lampung dikenal sebagai daerah tangkapan lobster yang dimanfaatkan oleh nelayan setempat sebagai sumber pendapatan utama. Untuk mengetahui potensi ekonomi dari budidaya lobster, maka dilakukan penelitian dengan tujuan menganalisis ketersediaan benih bening lobster (BBL) dan rantai pasok lobster sebagai suplai benih untuk kebutuhan budidaya lobster. Metode penelitian ini dilakukan dengan metode survei di Kecamatan Krui Selatan, Kabupaten Pesisir Barat, Lampung. Responden dalam penelitian adalah para nelayan penangkap BBL dan pengepul BBL. Penentuan responden dilakukan dengan metode snowball sampling. Hasil penelitian menunjukkan bahwa jenis lobster utama yang ditangkap adalah jenis lobster pasir dan lobster Mutiara. Hasil tangkapan nelayan lobster pada bulan gelap yaitu rata-rata 121 340 ekor BBL/bulan, sedangkan pada bulan terang rata-rata 4 680 ekor BBL/bulan, sehinnga dalam setahun benih yang dihasilkan mencapai 1.500.000 ekor BBL. BBL hasil tangkapan nelayan akan dijual pengepul kecil, selanjutnya ke pengepul besar, distributor dan eksportir. BBL terdistribusi ke berbagai wilayah mencakup Lampung, Bengkulu, Jambi, Palembang dan Jakarta. Marjin pemasaran yang diperoleh pengepul kecil dan besar mencapai 15 %. Produksi benih lobster yang melimpah di perairan Pantai Pesisir Barat Lampung sangat berpotensi untuk pengembangan budidaya pendederan lobster sebagai sumber ekonomi baru.
