You know what is the relationship between square electronic thermometer with roche spermatogenesis?

Square electronic thermometer is a kind of electronic thermometer, mainly used to measure the water temperature. Roche spermatogenesis from southeast Asia. Also called shrimp, white shrimp, prawns, Malaysia foot money WJH prawns, etc. , the title 'king of freshwater shrimp. Pond farming shrimp body is yellowish gray, not resistant to low temperature, suitable growth temperature is 20 ~ 34 ℃, higher requirements on dissolved oxygen. Roche spermatogenesis is omnivorous crustaceans, preference for animal food, the crude protein content in captivity feed requirements in 37 ~ 38%, which accounted for about 20% of animal protein content, plant protein of 17 ~ 18%. Newly hatched roche spermatogenesis of length 1. 7 ~ 2. 0 mm, after two months can be long to 3 cm of shrimp. Range of about 3 cm shrimp, after 5 months, the average weight of about 30 grams. Roche spermatogenesis is a fast growth, wide diet, nutrition rich economic shrimp. Since 1976, the introduction of the shrimp in our country, is now in guangdong, guangxi, hunan, hubei, jiangsu, Shanghai, zhejiang and other farming, more than a dozen provinces and autonomous regions, generally can reach 70 ~ 100 kg per mu, has achieved obvious economic benefits. The water of life but as a result of roche expounds the origin of 24 ~ 30 ℃, when water temperature down to about 16 ℃, slow, gradually die. So the suitable cultivation time in our country is only 4 ~ 5 months. So general breeding roche giant freshwater prawn ponds will be fitted with a square electronic thermometer, in order to focus on the growth of spermatogenesis temperature at any time.
