Can lobsters be raised in Ouchi Pond in Dongying, Shandong?

1. Lobsters can be raised in Ou Pond in Dongying, Shandong Province

2. Lobster living environment

1. Crayfish have strong adaptability. According to the survey, Spiny lobsters can survive in lakes, rivers, ponds, ponds, canals, and paddy fields, and can even survive in water bodies where some fish find it difficult to survive. Lobsters have strong adaptability to dissolved oxygen in the water. In an anoxic environment, they can not only climb ashore, but also use floating plants or aquatic plants in the water to lie on their sides on the water and use the gills on one side of their bodies to breathe. Survive.

2. Lobster has strong hypoxia tolerance. In anoxic water environment, it can climb ashore and perform gill respiration to survive. The pH value of water quality is in the range of 5.8 to 9, and it can still survive normally when the dissolved oxygen is lower than 1.5mg/L. Normal growth requires dissolved oxygen to be above 3ml/L.

3. Lobsters have a strong affinity for water flow. They like new and flowing water, swim upstream, and like to live in groups. In breeding ponds, they often gather in groups around the water inlet. On heavy rainy days, the shrimp can reverse the flow of water and go to the shore for a short stay or escape. When the water environment is not suitable, it will also climb up to the shore to roost. Therefore, the breeding site must have fence facilities to prevent escape.

It is affected by the Eurasian continent and the Western Pacific, and is a warm temperate continent. The basic climate characteristics are cold winter and hot summer, with four distinct seasons. Spring is dry and windy, and early spring is unstable, with late-spring cold often occurring. Late spring warms up quickly, and spring drought often occurs.

The main meteorological disasters include frost, hot and dry winds, strong winds, hail, drought, waterlogging, storm surges, etc. There is no obvious climate difference between the north and south of the territory. The annual average temperature is 12.8°C, the frost-free period is 206 days, and the accumulated temperature is not less than 10°C, about 4300°C, which can meet the needs of three crops in two years. The average annual precipitation is 555.9 mm, mostly concentrated in summer, accounting for 65% of the annual precipitation. Interannual precipitation changes greatly, easily causing droughts and floods.
