Study of some morphometric and meristic characteristics of Alepes vari (Cuvier, 1833) collected from the Arabian coast

Abstract

The present study examines the correlations between fifteen morphometric and ten meristic characters and total length (TL) of males, females, and combined sexes of Alepes vari (Cuvier, 1833) collected from Karachi fish harbor, West Wharf of Karachi Coast. Statistical analyses of linear regression relationships show mostly strong correlations (r≥0.70; p<0.05) between total length (TL) and most morphometric characters in males, females, and combined sexes, except the height of pectoral-fin (PFH), and pelvic-fin base length (PelFL); whereas, meristic characters were found to be constant and indicate weak or negative type correlations (r≤0.50; p>0.05) with total length (TL). Hence, according to our present results, there is a direct relationship between the total length of fish and all morphometric characters, which were found to be the best indicators of positive allometric pattern growth in fish. Moreover, analysis of the 2-sample t-test revealed (t-test; p>0.05) that no sexual dimorphism was reported in Alepes vari. Thus, our present study could be valuable in systematic classification, sexual dimorphism, and management of this species on the Karachi coast.

Karakter Meristik dan Morfometrik Spesies Ikan Asing Invasif Parachromis managuensis (Günther 1867) di Waduk Penjalin, Brebes, Jawa Tengah

“…Karakteristik tersebut berbeda dengan kondisi perairan di Waduk Penjalin yang merupakan perairan eutropik yang lebih sesuai untuk kehidupan ikan-ikan herbivora/planktivora (Sentosa et al, 2022). Panjang total ikan diketahui dapat menjadi indikator yang baik yang menjelaskan pertumbuhan ikan bertipe positif allometrik (Masood et al, 2022). Karakter morfometrik juga dapat mengindikasikan kondisi fisiologis, terutama reproduksi seperti pada ikan kerapu Cephalopholis miniata yang fekunditasnya semakin meningkat seiring meningkatnya panjang total ikan (Fadli et al, 2022) hal tersebut juga terjadi pada bilih Mystaecoleucus padangensis (Umar & Kartamihardja, 2017).…”
