Morphometric relationships of length-weight and length-length of four cyprinid small indigenous fish species from the Padma River (NW Bangladesh)

Bu çalışma, Padma Nehrinde (Bangladeş) dört önemli küçük yerli balık türünün (SIS), boy–ağırlık ve boy ilişkisini tanımlamaktadır. Geleneksel av aracıyla Mart 2006’dan Şubat 2007’ye kadar toplam 914 örnek yakalandı. Her örneğin, boy (cm) ve vücut ağırlığı (g) ölçüldü. Amblypharyngodon mola ve Lepidocephalus guntea’da pozitif allometrik büyümenin olduğu öne sürülse de Aspidoparia morar ve Puntius ticto’da “b” allometri katsayısı izometrik değere (≈3,00) yakın oldu. Sonuçlar boy ilişkilerinin oldukça korelasyon içinde olduğunu göstermiştir ($r^2$ >0,932; P

Padma Nehri’nde (Kuzeybatı Bangladeş) yerli dört küçük sazan türünün boy–boy, boy-ağırlık ve morfometrik ilişkisi

This study describes the length-weight (LWR) and length-length (LLR) relationships of four cyprinid important small indigenous fish species (SIS) from the Padma River, Bangladesh. A total of 914 specimens were caught by traditional fishing gear from March 2006 to February 2007. Length (cm) and body weight (g) for each specimen was taken by a digital slide caliper and balance, respectively. The allometric coefficient b was close to isometric value (≈3.000) in Aspidoparia morar and Puntius ticto, although it suggested positive allometric growth in Amblypharyngodon mola and Lepidocephalus guntea. The results further indicated that LLRs were highly correlated ($r^2$ >0.932; P<0.001).
