How to Identify Red Porgy

To identify Red Porgy (Pagrus pagrus), look at these key features.

Physical Characteristics

Body shape

compressed

Coloration

Adults are typically reddish-silver to pinkish-red dorsally, fading to silvery-white on the belly. Juveniles may have faint vertical bars or spots that fade with age. Fins are often tinged with red or pink.

Scale type

ctenoid

Mouth position

terminal

Distinctive features

Deep, compressed body, Large eyes relative to head size, Prominent canine-like teeth at the front of both jaws, followed by molar-like teeth, Slightly convex dorsal profile of the head, Absence of black spot at the origin of the lateral line (distinguishes from some similar species)

Dorsal fin

Single dorsal fin with 12-13 spines and 10-11 soft rays. The spiny portion is longer than the soft-rayed portion.

Tail fin

Moderately forked caudal fin.

Pectoral fin

Long and pointed pectoral fins.

Distinctive fins

Anal fin with 3 spines and 8-9 soft rays. Pelvic fins are thoracic.

Identification Tips

1. 1

   Coloration

   Look for the characteristic reddish-silver to pinkish-red body, fading to white on the belly. This is a primary identifier.

2. 2

   Body Shape

   Note the deep, compressed body, typical of many porgies.

3. 3

   Teeth

   Examine the mouth for prominent canine-like teeth at the front and molar-like teeth further back, adapted for crushing shells.

4. 4

   Absence of Black Spot

   Crucially, Pagrus pagrus lacks a distinct black spot at the origin of the lateral line, which helps differentiate it from some other porgy species like Pagrus auriga.

5. 5

   Fin Spines/Rays

   Count the dorsal fin spines (12-13) and soft rays (10-11) for definitive identification, though this is often difficult in the field.
