Abstract
Ikan layang (Decapterus macrosoma) merupakan komoditas hasil tangkapan paling banyak di dua perairan yaitu Prigi dan Muncar. Otolith merupakan organ yang berfungsi mengatur keseimbangan, pendengaran, koordinasi arah renang, dan orientasi. Bagian keras di kepala ikan ini biasa digunakan untuk menentukan jumlah stok populasi ikan dan hubungan panjang tubuh ikan (FL) dengan panjang total otolith (TL). Tujuan penelitian ini ialah menentukan hubungan panjang tubuh ikan (FL) dengan panjang total otolith (TL) dengan menggunakan uji t dan menentukan titik landmark otolith dengan software SAGE. Penelitian dilakukan dengan metode deskriptif. Pengambilan sampel ikan layang diambil secara acak pada kedua perairan. Hasil analisis data didapatkan nilai b<3 dengan kondisi alometris negatif pada ikan layang di perairan Muncar dan Prigi. Pengujian uji (t-test) didapat nilai p>0.01 menyatakan bahwa tidak ada perbedaan bentuk otolith secara signifikan di dua perairan. Persamaan panjang otolith yang kuat berlaku untuk perairan Prigi dan Muncar. Geometric Analysis mendapatkan bahwa tidak ada perbedaan shape atau bentuk otolith secara siginifikan di dua perairan. Analisis geometric terhadap morfometri otolith pada kedua lokasi penelitian menunjukkan bentuk yang sama sehingga sebaran stok di dua perairan merupakan satu stok yang sama. Sebaran stok ikan layang (Decapterus macrosoma) pada wilayah selatan Jawa Timur meliputi perairan Muncar Banyuwangi dan Prigi Trenggalek. Penelitian selanjutnya bisa dilakukan pada wilayah Jawa Tengah dan Jawa Barat untuk menentukan wilayah sebaran populsi ikan tersebut.
English Abstract
Shortfin Scad (Decapterus macrosoma) is the most catch commodity in two waters, Prigi and Muncar. Otolith is an organ that functions to regulate balance, hearing, swimming direction coordination, and orientation. The hard part on the head of the fish is commonly used to determine the amount of fish population stock and the relationship of fish body length (FL) with total otolith length (TL). The purpose of this study was to determine the relationship of fish body length (FL) with total otolith length (TL) using t test and determine the otolith landmark point with SAGE software. The study was conducted by descriptive method. Sampling was taken randomly in both waters. The results of data analysis obtained the value of b <3 with negative allometric conditions on shortfin scad in the waters of Muncar and Prigi. Tests (t-test) obtained p> 0.01 stated that there was no significant difference in the form of otoliths in the two waters. The strong otolith length equation applies to Prigi and Muncar waters. Geometric Analysis found that there was no significant difference in shape or form of otolith in the two waters. Geometric analysis of the morphometry of otoliths at the two study sites shows the same shape so that the distribution of stocks in the two waters is the same stock. The distribution of shortfin scad stocks (Decapterus macrosoma) in the southern region of East Java includes the waters of Muncar Banyuwangi and Prigi Trenggalek. Further research can be carried out in the Central and West Java regions to determine the distribution area of the fish population.
