Como identificar Cambucu

Para identificar Cambucu (Centropomus parallelus), observe estas características principais.

Características físicas

Formato do corpo

elongated

Coloração

Generally silvery-gray to olive-green dorsally, fading to silvery-white ventrally. The lateral line is distinctly dark. Fins are typically dusky or yellowish.

Tipo de escama

ctenoid

Posição da boca

superior

Características distintivas

Prominent, prognathous lower jaw extending beyond the upper jaw., Lateral line extends conspicuously onto the caudal fin., Two distinct dorsal fins, the first with 8 spines and the second with 1 spine and 10-12 soft rays., Anal fin with 3 spines and 6-8 soft rays, with the second anal spine being notably longer and thicker than the third., Pectoral fins are relatively short., Pelvic fins are thoracic.

Nadadeira dorsal

Two dorsal fins; the first with 8 strong spines, the second with 1 spine and 10-12 soft rays. The first dorsal fin is typically higher than the second.

Nadadeira caudal

Moderately forked caudal fin, with the lateral line extending prominently onto it.

Nadadeira peitoral

Short and rounded, positioned low on the body.

Nadadeiras características

Anal fin has 3 spines and 6-8 soft rays, with the second anal spine being significantly longer and stouter than the third. This is a key diagnostic feature.

Dicas de identificação

1. 1

   Lateral Line

   Observe if the dark lateral line extends clearly onto the caudal fin. This is a definitive characteristic for Centropomus species, and its prominence can help distinguish C. parallelus from some other snook species.

2. 2

   Second Anal Spine

   Carefully examine the anal fin. The second anal spine of C. parallelus is notably longer and thicker than the third anal spine. This is a crucial distinguishing feature from other snook species like C. undecimalis (Common Snook) where the second and third anal spines are more subequal.

3. 3

   Body Depth

   C. parallelus generally has a deeper body relative to its length compared to the more slender C. undecimalis, giving it the common name 'Fat Snook'.

4. 4

   Size

   While not always definitive, C. parallelus typically reaches smaller maximum sizes (up to 60 cm TL) compared to the Common Snook (C. undecimalis) which can exceed 1 meter.
