| dc.description.abstract | Aktivitas penangkapan ikan kakatua di perairan Karimunjawa perlu untuk diperhatikan mengingat ikan kakatua merupakan produsen utama yang menghasilkan sedimen berpasir di ekosistem terumbu karang serta mengontrol pertumbuhan alga yang berguna untuk menjaga kesehatan terumbu karang. Penelitian ini bertujuan untuk menghitung parameter biologi ikan kakatua di Perairan Karimunjawa, mengetahui status sumberdaya stok ikan kakatua di Perairan Karimunjawa serta membandingkan tren penangkapan selama rentang waktu 2015 - 2020. Penelitian ini menggunakan data fish landing monitoring WCS. Analisis data yang digunakan adalah analisis pertumbuhan ikan, analisis laju mortalitas dan laju eksploitasi, analisis pola rekrutmen, dan analisis spawning potential ratio. Hasil penelitian didapatkan bahwa ikan kakatua spesies Bolbometopon muricatum memiliki laju eksploitasi terbesar dengan laju pertumbuhan terkecil. Hal tersebut mengakibatkan spesies Bolbometopon muricatum memiliki tingkat kematian terbesar akibat aktivitas penangkapan. Kondisi status stok sumbedaya ikan kakatua di perairan karimunjawa bervariasi dengan persentase 8 hingga 41%. Nilai SPR selama kurun waktu 2015 - 2020 menunjukan bahwa tren penangkapan ikan kakatua bersifat fluktuatif. Perlunya pengendalian terhadap spesies yang mengalami over exploited demi terciptanya perikanan yang berkelanjutan | id |
| dc.description.abstract | Fishing activities of parrot fish in the Karimunjawa waters need to be
considered because parrot fish are the main producers of sand sediment in coral
reef ecosystems and to control algae growth which is useful for maintaining the
health of coral reefs. This research aims to calculate biological parameters of
parrot fish in Karimunjawa waters, to evaluate the status of parrot fish resources
in Karimunjawa waters and to compare fishing trends during the 2015-2020. This
research uses fish landing monitoring of wild conservation society (WCS). The
analysis data used was fish growth analysis, mortality rate and exploitation rate
analysis, recruitment pattern analysis, and spawning potential ratio analysis. The
results showed that the Bolbometopon muricatum had the largest exploitation rate
with the smallest growth rate having the largest fishing mortality. The stock status
of parrot fish in Karimunjawa waters varies with percentage of 8 to 41%. The
Spawning potential ratio value during 2015 - 2020 shows that the trend of parrot
fishing is fluctuating. Control needs to be done on over exploited resources so that
can create sustainable fisheries. | id |
