Decapterus russelli (laying)

Morphology

Decapterus russelli has a smoth scale and the body shape like a cheroot flat, pectoral fin more short

than head long, maxilla hear to get bend of eye . pertoral fin has a falcare shape and the tip fin to

get second dorsal fin. Decapterus russelli include stenohdyn fish is mean can be live to consume

plankton, especially zooplankton. The small cycle in back and anus cycle and concist lateral line, it

has two dorsal fin, the firt dorsal have eight line and second dorsal fin have one line. And fin has

there line that strong and in bottom surface is quite. The gills has four pairs. The body color is

blueish green.

Morphology

Siganus have lateral flat of body and protected by sicloid scale, simple linea – lateralis. Small mouth

position located in terminal. The jaw completed by small teeth and part of pectoral completed with

spine to direct ahead and body color is dark quite . the all of body is black color, it has dorsal

fin,pectoral fin, and fin and caudal fin. The caudal fin is homocercal with the tip of fin is ponted . the

eyes is big, usually the dorsal fin +_ 13 , and the body is lateral flat . the skin is located in under skin.

Morphology

The body surface is grey color or quite dark, it dorsal fin usually the spine located in pointed. The

caudal fin us homocercal. The scale type is cteneid scale. The body separated has three. Part are

head, body and tail. The body is simetris bilateral it has lateral line, the mouth located in tip of

nose. The eyes located in lateral, between body and head. Consist of gill, the and fin is erect and

stomach scale near of thorax scale. And dorsal scale is scale and has operculum.

Anatomy

Respiration system

It use gill to breath, take oxygen in air in embryo use skin and yolk sale. The gills

separated by curve bone of gill, filter bone of gill, oxygen that pass by blood and has two

chambar and out gill that marking by open and close the operculum it has additional

breath is labirin .

Excretion system

The metabolism process like gasses, liquid and solid pass by skin, kidney and digestive

system.

Reproduction system

Fertilization, if the gonad is mature, the gonad can cut from female body bisexual. The

urogenital is different, it done fertilization in external.

Digestive system

It has stomach and intestine, but read drugs in mouth hole cause have teeth. The

stomach is pink color, and attach by intestine. The intestine is longer more than the

body, it has digestive system are hepar, bile , pancreas , intestine , esophagus mouth

hole and additional organ like hepar gland , bile and pancreas gland.

Circulatory system

The organ like heart, artery, vena and the substance like blood plasm and trombocyte.

Before the atrium consist sinus venosus that collect carbon dioxide from tertian organ.

Blood from so into atnum has pass sinuautrial septum, blood ventricle passed by pump

to ventralis aorta, to gills, and changing oxygen and carbon dioxide in gilss. Then blood

that contain oxygen toward heard then to dorsal, ventral, and then back to heart and

heart only has two chamber.

Chanos chanos (bandeng)

Morphology

The body is slim with the caudal fin that usually branching so can swim fast. The body is silver

color, the mouth does not have teeth. The mouth is pointed the scale is smooth, and look shine

but near the back is quite dark. The eye that covered by fat. The scale type is cycloid, has

additional scale near stomach scale. The torpede shape in caudal fin toward to back. The

transparent membrane covered the eye, the body is simetris. The female has there anus and the

body is size it bigger move then mole.
