Jack Crevalle ( Caranx hippos )
The crevalle jack, Caranx hippos (also known as the common jack, saltwater jack fish, black-tailed trevally, couvalli jack, black cavalli, jack crevale and yellow cavalli) is a common species of large marine fish classified within the jack family, Carangidae. The crevalle jack is distributed across the tropical and temperate waters of the Atlantic Ocean
The Jack Crevalle reminds one of the Permit but is part of the Caranx family which is highly sought after by sport fishers. Its older brother is the Giant Trevally (Caranx ignobilis) and it is found in areas of the Pacific and it is one of the most valued and desired species.
There is also a variety in the Pacific called Pacific Crevalle Jack (Caranx Caninus) Which is smaller. Both species are similar and can have different colors, some are whiter and some are darker according to the environment they are in.
In Nicaragua, fishes can grow up to 66 pounds. The Jack Crevalle is a fish that aggressively attacks bait even biting several times during the same throw. They are very active during days when other fish are calm. Their diet is based on shrimp, small sardines and other types of crustaceous like crabs that emerge from the sand when the sea level is low. This is also why it is easy to catch them from the shore with Jerk baits.
They are very fast and offer an important resistance when captured; they tilt their bodies generating a stronger resistance by using their weight. If they come out of the water they make a very distinct sound and that is the right moment to put them back in.
These fish are easy to find because they are quick to swim all along the coast where they prefer to swim. Due to their speed, it is not rare for them to bite twice when fishing them with bait, or even while the bait is still in the air. They are also found in rivers with the high tide.
