PHYSIOLOGY AND MORPHOLOGY

Corvinas has some characteristics that distinguish them of others animals:

- They are strictly aquatic all the life. - They extract oxygen dissolved in the water by means of the gills that are arranged to each side of its head. - Its locomotion is made by means of fins that allow in addition to stay him in balance. - One swim bladder is used to regulate the depth to which the fish wish to be. - They have grudges that them they protect. - They do not have eyelids in eyes. - They have a heart with two cavities. - Its brain is considered most primitive of all the vertebrates. - Its skeleton is formed by bones. - Its corporal temperature is regulated by the room temperature (poikilotermos animals).

Corvina is a fish of compressed body laterally what it allows him to generate I swim efficient in the ocean currents, the inferior jaw it projects clearly in front of the superior one, its dorsal fin is enough long, has of 20 to 35 radios, anal fin has of 6 to 13 radios and their vertebrae correspond to a number from 24 to 29.

Su colorful, gorgeous she is variable, with tonalities that they go from the dark colors of the phantom of narrow band a clear colors and of beautiful bluish or greenish tonalities silver with points in flanks. His eyes are quite great for the dimension of the head which is indicative that uses the vision like part of the identification of prey and companions in the shoal of fish.

lateral line leaves from the superior part of porcule and finishes in the base of the fin of great volume, it sees clearly noticeable a flank of the fish and it serves to him to identify the living movements of the companions and signals of potential prey. Some corvinas present/display small chins in their mouth that can have property to detect small oscillations of movement when the fish one is looking for his food in the bottoms.

Like previously the Corvina is explained is considered a fish that hunts in the bottoms in where it finds his favorite prey, crustaceans, fish and mollusks. Although they are very popular between the aquatic to maintain them in captivity a challenge represents everything, since they are very delicate to the changes of alkalinity or acidity of the water, and to demand that the conditions of the water be of extreme purity since they are very susceptible to suffer diseases within a phantom that includes/understands fungi, virus and bacteria.

” or weak fish knows like “ weakfish them since its mouth is fleshy but very weak, which produces that easily it withdraws when it fishes. Generally nothing in shoals of fish of variable amount of individuals, although great specimens can be observed to them to swim solitary by brief waters of the coastal estuaries. In some of the species have been verified that the females have a rate of growth superior to the one of the males

CUSTOMS AND REPRODUCTION

corvinas are fish that are transferred from a zone to another one in shoal of fish (migratory fish), this allows them to present/display before the predators image of being a creature of much greater dimensions in addition to to facilitate the obtaining to them of the appraised food, that not in all moments one is available.

Like characteristic present in the behavior of the fish, appear feeding tips in where corvinas are fed actively until arriving at the satiety point; in the moments of greater level of annual feeding the rate of growth is greater.

These fish are great specialists in locating imprisoned in the bottoms in where they find manjares such as shrimps, sardines, crabs, annelids and other species. It is possible to be considered that they are following of shoal of fish and they move next to the spots of shrimp, sardines and other species.

corvina reproduces in period between the spring and the summer; in a taken case like example, the Cynoscion Analis, this one are a water reproducer opened although other species they prefer the coastal estuaries stops to reproduce; fertilization it is of external type, the parents do not take care of eggs, nor it young, being voracious predators of such if it is possible to them considering the great amount of eggs deposited in the process of reproduction is that the species maintains amounts regular of specimens in the sea, in the case of young females a number of eggs is considered of 100,000 and in adult females of up to 1 million, the egg has average of 1,5 millimeters of diameter, the population average of reproducers are in the rank of the three years of life.

The FISHING OF the CORVINA

the corvina is a beautiful fish with beautiful variable tonalities in the different species, but without doubt whatever its particular species its coloration is beautiful; some corvinas of small length others of great length and because not to describe the gentleness of its lips that makes a work of fishing of high performance for the fisherman.
Nothing with rhythmic sequence in a dream world of great dimensions, plenty of immersed dangers in crystalline waters of the vast ocean in where its powerful life hangs sometimes of fauces of the predator that looks for with anxieties the exquisite flavor of its meat and of those terrestrial beings who outside the liquid element share this necessity to devour it.
