PARTICULARITIES OF THE ANATOMICAL BODY OF CRUCIAN CARP

Abstract

The fish reach the kingdom of creatures, aquatic ridge creatures, a number of bark-like creatures, the birthplace of the bark, the species of crucian carp is extraordinary. The skeleton of fish consists of the axial skeleton of the body, the skeleton of the organs of the swimmers (skeleton of the swimmers), and the skull. The axial skeleton of the crucian carp bears two species: a tulub and a caudal one. Its basis is made up of a spinal column consisting of ridges that are connected to each other, and in the tubular section there are ribs that are spread out on the sides and protect the internal organs of the fish. As a result of our investigations, the specificity of the body shape of the common crucian carp was established. In this case, a complex of standard morphological research methods was put in place. Comprehensive classical morphological and anatomical methods of experimental investigation were used, which included: external examination of the object under investigation, dissection of organs, their outline (color, consistency, shape), identified topography The details of the description of the organism along its contours were photographed, which in the end The bag made it possible to carry out a detailed macroscopic investigation of the somatic system in crucian carp. The body of the crucian carp is usually bilaterally symmetrical and for the description of other organs we have a vicoristic trimeric vimir, then there are three planes. The body of the crucian carp has a flattened head section, a back with a slight ridge, a flattened ventral part of the body and a flattened tail. The color of crucian carp ranges from silver-yellow to bronze depending on the genus. The color is darker in the dorsal part and lower in the ventral part. The crucian carp has its head, body and tail. At the head of the crucian carp, the mouth, nose openings, and eyes are opened. The body and tail of the crucian carp are covered with a brush, which tightly fits one to the other, and ventrally behind the head section a larger plate is formed from the fish from the pectoral swimmers lateromedially. On the body of crucian carp one can see a continuous skin fold along the medial line dorsally along the dorsum, and then it goes ventrally to the anal opening and creates unpaired swimmers. From the anal opening, the male swimmers are ventrally expanded. The main function of swimmers is to regulate the movement of the fish in the singing order and directly, maintaining the balance of the water. The swimmers of crucian carp are dorsal, caudal and anal, and gypsy are thoracic and ventral. On the back of the dorsal part there is an unpaired dorsal swimmer, a long, garneous apology and changes to the side of the tail, whose first exchanges are hard and the first may have serrations on the caudal edge. The tail swimmer looks like a wrapped trapezoid, has two blades, and the tail section ends with it. The paired pectoral swimmer extends caudally from the zebra openings on the sides, and behind it the ventral swimmers protrude ventrally and lie horizontally. The anal swimmer grows ventrally between the body and tail, changing the alignment. On the front of the head, caudally on the sides, a pair of zyabrova slit on the right and left is rotated. It is sculpted vertically and its lower end reaches just below the lip, and is shaped aborally between the body and head. It is covered by a yellow cap, which forms the bulging surface of the head.
