The main differences between flat sea bream and yellow-finned fish are different subject classifications, different morphological characteristics, and different living habits. The details are as follows:

1. Different subject classifications

1. Flat sea bream

Flat sea bream is a species of fish from the order Perciformes, the seabream family, the genus Flat sea bream, and the sea bream.

2. Yellow-finned fish

Yellow-finned fish is a species of fish from the order Perciformes, the family Breamidae, the genus Acanthora, and the yellow-finned acanthus.

2. Different morphological characteristics

1. Flat seabream

The body is nearly oval and the sides are flat. The dorsal edge is deeply arcuate and narrow; the ventral surface is rounded and blunt, almost straight. The head is large and the back is high. The body is covered with large and thin round scales, and the head, gill covers and cheeks are all scaled; the spines of the dorsal fin and anal fin have well-developed scale sheaths, and the fin rays are also scaled. Lateral line complete, parallel to dorsal margin. The pectoral fin is located on the lower side, with a long tip, and the rear end can reach the anal fin. Pectoral fin position. Caudal fin bifurcated. The back of the body is blue-grey, the abdomen is lighter, and there are multiple rows of dark longitudinal bands on the sides of the body. The dorsal fin and caudal fin are dark with black edges, and the pelvic fin is yellow.

2. Yellow-finned fish

The body is oblong, with flat sides and a narrow back. It gradually slopes from the starting point of the dorsal fin to the tip of the snout. The ventral surface is round and blunt, and the curvature of the snout tip is small. The body is covered with weak comb scales, and the head is covered with scales except for the septum between the eyes, the preopercular bones and the tip of the snout. The spines of the dorsal and anal fins have well-developed scale sheaths, the base of the fin rays are scaled, and the lateral lines are complete and arc-shaped. The living body is blue-gray with yellow, and there are several gray longitudinal bands on the side of the body, running along the scales. A small part of the dorsal fin, anal fin and the edge of the caudal fin are gray-black, and most of the pelvic fin, anal fin and the lower leaf of the caudal fin are yellow. ?

3. Different living habits

1. Flat sea bream

Flat sea bream is a tropical and subtropical shallow sea bottom fish, and its living habits are basically the same as those of yellow fin. Same for sea bream. It usually inhabits shallow waters within a depth of 50 meters and does not move far. When young, the fish lives in the inner bay and is highly resistant to harsh environments. ? It is an omnivorous fish, feeding on bivalves, shrimps, crabs, mantis shrimps, barnacles and seaweed. It has no specificity for bait and will eat all fresh bait. Under artificial breeding conditions, they can eat compound feed.

2. Yellowfin bream

Yellowfin bream is a warm-water bottom fish in shallow seas. It lives in coastal waters and estuary bays. The temperature suitable for juvenile fish is narrower than that for adults. The adaptive temperature for survival is 9.5-29℃, the critical lethal temperature is 8.8℃ and 32℃, and the optimal temperature for growth is 17-27℃. It has no long-distance migration habit, but has obvious reproductive migration behavior. The food organisms of yellow-finned sea bream include longtails, branchials, fish, benthic amphipods, opisthobranchs, polychaetes, benthic seaweeds, ophiopods, brachyurans, chaetognaths, and cephalopods. There are 13 taxa including stomatopods, stomatopods and nemertata.
