Goldfish (definite introduction)
If you want the goldfish at home to grow, It is necessary to understand the gender of goldfish separately. Below, the editor will teach you how to identify male and female goldfish from three aspects.
Male and female goldfish are mainly distinguished from the following aspects:
1. Identification of external appearance
(1) Body shape Identification: Male goldfish are generally slightly longer, while female goldfish are shorter and rounder. During the pregnancy period, the abdomen of female fish is more distended than that of male fish.
(2) Identification of caudal peduncle: Male fish are slightly stronger than female fish.
(3) Identification of pectoral fins: Careful inspection can reveal that the male fish is slightly pointed and longer, and the first spine of the pectoral fin is thicker and harder; the female fish is short and round, and the first spine of the pectoral fin is not too sharp. hard.
(4) Identification of the cloaca: Looking from the belly, the cloaca of the male fish is small, narrow, and concave; the cloaca of the female fish is large, slightly round, and convex outward.
2. The difference in color
Male and female goldfish are slightly different in body color. Male fish generally have bright colors, while female fish Slightly lighter, during the growth and development period, the male fish's body color is more vivid.
3. Feeling and movement
Gently hold the fish’s abdomen with your hands, and feel with your middle and ring fingers that there is an obvious hard line on the abdomen of the male fish. The abdomen is soft. When walking by the fish pond, I stepped on my feet and observed that the male fish was swimming fast and fast, while the female fish was slower.
Chasing stars. As the temperature rises, goldfish will show a second characteristic during the spawning period - star chasing. This is the easiest and most accurate time to identify the gender of goldfish, and it is also the easiest way to master. The star chasers of male fish appear on the first spine of the front pectoral fin and the edge of the gill cover. In many cases, there are star chasers on each ray of all pectoral fins. The front ones are obvious, and the back ones can only be observed with caution. These rough white spots are star chasers.
Using the above identification methods, you must also rely on years of breeding experience and daily careful observation to accurately identify male and female goldfish
