Introduction
There are 50 species in 15 genera.
Mackerel and tuna are a family of marine fish.
Hunting mackerel are almost always the reason for this,
when schools of small fish chase each other
and individuals jump out of the water in all directions.
Carangoides bajad
Orange-spotted trevally or Gold-spotted trevally
Maximum length: 53 cm
Depth: 1 - 90 m
Silvery or yellow with orange spots.
The yellow one is more common in the red sea than the silvery one.
To get closer to their prey, they accompany yellow mullets.
Not shy.
