Abstract

Udang Bintik Kacang (P. hardwickii) adalah salah satu udang dengan keluarga Penidae. Pengukuran morfometri dilakukan untuk melihat hal -hal yang mempengaruhi bentuk spesies. Penelitian ini bertujuan untuk memberikan informasi tentang studi morofomterik Udang Bintik Kacang (P. hardwickii) yang ditangkap di perairan Samboja, Kutai Kartanegara. Penelitian ini dilakukan di perairan Samboja, Kutai Kartanegara, pada Oktober-November 2021. Sampel yang digunakan adalah 300 Udang Bintik Kacang (P. hardwickii). Studi morfometrik pada Udang Bintik Kacang (P. hardwickii) menggunakan analisis dengan analisis uji kovarian (ANCOVA) untuk melihat 18 kovariat morfometrik yang mempengaruhi total panjang (PTO). Berdasarkan hasil analisis tes univariat ANOVA, ditemukan bahwa 18 morfometrik memiliki nilai signifikan <0,05 yang berarti H1 diterima, bahwa semua morfometrik mempengaruhi PTO. Selanjutnya, analisis ANCOVA dilakukan, hasilnya adalah 9 morfometrik yang memiliki nilai signifikan <0,05, yaitu, panjang kepala (PK), panjang ruas keempat (Pre), panjang internode keenam (PRN), panjang tanpa kepala (PTK), panjang segmen bawah ketiga (PTB), panjang segmen bawah keempat (PEB), panjang segmen bawah kelima (PLB), panjang segmen bawah keenam (PNB) dan panjang ekor (PE). Sehingga hasil analisis uji ANCOVA memperoleh pengaruh mofometrik paling signifikan PTO, yaitu 9 morfometer.

Abstract

In this study, as a data-poor fish stock assessment method CMSY was used to assess the current stock status of the Sword Prawn in Samboja Waters. A total of 13 years catch data (from 2012 to 2024) was used in the analysing process of study. Estimated CMSY model parameters with confidence intervals are as folloe: r=0.47 (0.29-0.7) year-1, k=14.9 (10.1-22) ton, MSY=1.75 (1.23-2.36) ton, B2024=4.2 (0.43-5.89) ton, BMSY=7.45 (5.05-11) ton, F2024=0.28 (0.2-2.71) year-1, FMSY=0.23 (0.14-0.38) year-1, B2024/BMSY=0.56 (0.05-0.79) and F2024/FMSY=1.18 (0.84-11.4). Our study has found that sword prawn population in Samboja waters has been decline due to overfishing since 2017. Until now, regulations regarding catch quotas have not been established or implemented. Therefore, it is recommended to create regulations related to catch quotas based on research findings and reduce fishing mortality to maintain populations and prevent further biomass decline.
