The American striped wolf owl is also known as the striped eagle, the sea wolf owl, and the line owl. Slim body, smooth lines. The head is smaller and the tail is a positive tail type. The body is bright and light white. There are 7 narrow black stripes on the back of the body to the midline of the body. This is its main feature and hence its name. Individuals weighing 4.5 to 9 kg are common. Native to the eastern coast of the United States, north latitude 3858' to 2500' (Figure 22).
The fish is a wide-salt, wide-temperature fish, widely in freshwater, brackish water and seawater. Can live in the water temperature of 4 ~ 33 Â°C, the survival temperature of 1 ~ 38 Â°C, the optimum growth temperature of 27 ~ 27 Â°C. It can grow in 0.1% to 2.5% salinity waters, and up to 3.5% in high salt waters. Striped wolves are carnivorous fish. In natural waters, larvae feed on zooplankton such as copepods and cladocerans. They feed on small shrimps after a bit of a big hock. Adult fish feed on fierce fish and it is easy to fish. Under artificial breeding conditions, larvae fed Artemia larvae and later fed Artemia adults, fish, shrimp, and pelleted food. During the growing season, chilled fish, shrimp and food are fed. The fish showed obvious upstream spawning and spawning habits. The spawning period is from mid-April to mid-June, and can even be extended to July. Juvenile larvae and spawning groups are concentrated in the estuary area. The egg diameter 1.8 mm, spawning water temperature 10 ~ 25 Â°C, peak at 15 ~ 18 Â°C. Fertilized egg hatching temperature 19 ~ 24 Â°C, early larvae incubation temperature of 10 ~ 26 Â°C, the best 18 ~ 24 Â°C. The salinity at the time of nursery is 0.1% to 0.3%, which is favorable for the development of fertilized eggs. The striped wolf eel has delicate meat, high nutrition, high economic value, fast growth, and strong disease resistance. In addition, since the 1980s, the United States has crossed this fish with the golden horned owl, which represents a good hybridization advantage. It grows at a moderate temperature and grows rapidly. It can reach up to 1 kilogram body weight a year. It has been widely used in production. It is the second most cultivated species in the United States after the channel catfish. In the southern part of Taiwan Province, the fertilized eggs of this hybrid were introduced in 1991. The annual water temperature was kept above 18Â°C, the growth rate was very fast, and the feed coefficient was 1.7. The average yield was 11 kg/m3. In recent years, mainland China has also introduced a small amount of households, which is expected to expand further.
