The Blue fish Main Characteristics

The blue fish is a member of the pomatomidae family and is a species of fish very difficult to distinguish, since both sexes are the same size, and with the same pattern of colors. They are native to the American coasts, and European-African Atlantic Ocean.

These fish can live up to fourteen years, and reach their sexual maturity at two years of life.

It’s worth mentioning that when snappers are one year old measure approximately twenty-five centimeters, and they weigh almost two kilograms.

Then, when they are five years old, they measure sixty-five centimeters, and weigh three and a half kilograms.

Finally,  when these wonderful fishes are 10 years old or more they reach almost ninety centimeters, and  their maximum weight is ten kilograms.

These fish have been considered primitive relatives of tunas , but their exact relationship with other fish is still to be discussed. We invite you to read our article the anatomy of fish to learn about such an interesting topic.

Other Traits

Their name isn’t totally related to their color since the blue fish have a greenish blue coloration that turns dark blue on their back, and silvery white on their lower body.

Their body is covered with relatively small scales and a straight lateral line. Moreover, they have a dorsal fin and an anal fin, and their tail is slightly bifurcated.

One of the characteristics that distinguish the blue fish is that its lower jaw is extended downwards, and is aligned with the lower jaw with extremely sharp teeth.

Like most bony and cartilaginous fish,  the blue fish usually inhabits warm and warm waters of the western Atlantic Ocean, from Nova Scotia to Uruguay and on the West African coast. . Yet, they are also found in the Mediterranean, and Black seas In the Indian Ocean, as well as in Tasmania and Australia.

How  Blue fish Reproduce?

The spawning of blue fish takes place between the months of June and August when the water temperatures reach between 64ºF and 72ºF..

It mainly occurs on the high seas, specifically on the continental shelf. Once the eggs have hatched the larvae remain on the water’s surface, so they are swept by the prevailing currents along the entire continental shelf.

Fertility, or the number of eggs that a female produces, is closely related to its size.

A female measuring fifty-two centimeters can easily produce nine hundred thousand eggs; while one that measures about sixty centimeters, can spawn more than one million eggs in a single season.

What do Blue fish Feed On?

The blue fish is a powerful predator of other fish; Juveniles usually feed on small shrimps, anchovies, and other mollusks, while adults eat black tetra fish Atlantic mackerel, anchovies, and other young fish.

There are more than seventy species of fish and invertebrates,  that have been found in the stomach of the blue fish.

blue fish : shrimps are one of the blue fish main preysThey usually feed on schools, actively chasing prey at low tides, or in shallow waters, where their food is much easier to catch.

It’s important to point out that this species has a legendary eating habit, as they have the reputation of violently breaking the schools of fish, biting, paralyzing and killing a large number of fish, larger than they are able to eat.

Their hunting strategy consists in driving their preys to the shallower coastal areas, where it’s  easier to paralyze and capture the fish that try to escape from their lunges..

Where do Blue Fish Inhabit?

Blue fish are found in all oceanic and coastal waters except the eastern and northwest Pacific. Adults can be found in estuaries and brackish water, but they are more common in clean, high-energy waters, such as surfing beaches and rocky headlands

They live in coastal areas and offshore of coastal regions at temperatures ranging between 66 and 72 degrees F. They can tolerate low temperature waters and at the same time maintain a body temperature of up to forty degrees Celsius.

The Youngest specimens (first year of life) can be obtained most of the year in estuaries, along the coast, and in the mouths of rivers.

When they begin to grow they also begin to migrate, and the larger they are, the distances they travel are also larger.

This species normally travels in large schools that can contain up to several thousand individuals. Bluefish shows an annual migration pattern that is apparently the key to seasonal warming and cooling of coastal waters.

Larger fish initially inhabit deeper waters, but move progressively towards the coast in shallow areas as summer progresses. Although many adult fish migrate south during the fall, their majority migratory movement seems to be offshore towards the warmer waters of the continental shelf.

Tips for fishing Blue fish

The blue fish is caught in large quantities by fishermen, especially between the months of May and November, where they are more accessible either on the beaches, bays, and out to sea.

Fishermen specializing in this technique argue that this fish can be fished from a boat, or on the shore, along the entire port, the beach, the jetty, and on the city dock.

However, since they have sharp teeth, wire should be used to hook the blue fish.

It’s proven that the best catches are achieved between the months of July to September, and from a ship, because those that are out to sea are usually the largest. For this reason, deep-sea fishermen put plug and tube lures, as well as deep dusters, which are required to reach the blue fish.

The fly fishing is the most common technique to catch this species.

It’s highly recommended to keep in mind that bite protectors are an absolute necessity when aiming at bluefish.

Many fishermen like wire, and it certainly has utility for this type of fishing. However eighty-pound test hard mono is the best option for this species. It’s quite resistant to abrasion and has the additional advantage of being less bothersome for incidental species such as striped bass that tends to inhabit many of the same places as blues.
