Problems solved by technology

[0005] The outstanding feature of the present invention compared with the existing Yangtze river anchovy summer flower fingerling transportation technology is that it has created a set of simple methods from dragging net training to long and short-distance transportation, which solves the problem of scale extremes during the long-term transportation of Yangtze river sword anchovy summer flower fingerlings. The problem of easy falling off, the transportation density and transportation survival rate are significantly improved, and the method is simple and easy to learn, easy to promote, suitable for large-scale production and transportation

Embodiment 1

[0006] Example 1: On August 23, 2011, the indoor cement pond fish fry were transported to the pond in the field in the Fengxian Seed Technology Center Base of Shanghai Fisheries Research Institute. A few days before transportation, the fry should be pulled into the net for exercise. Stop feeding the fish for 8-10 hours before the netting exercise. Use a soft 80-mesh sieve tulle to pull the fry into the net and concentrate the fry in the net. Allow the fry to adapt to the net for 5-10 minutes, and then let the net open a mouthful to allow the fry to swim out of the net freely, so that the fry can be exercised continuously for 3-5 times to allow the fry to adapt to the pulling operation. The transportation tool is a plastic bucket, the diameter of the bucket is 32cm, the height is 35cm, and the capacity of the bucket is 28 liters. The water in the bucket is 20 liters when transporting the fish, which is 2 / 3 of the bucket; the day before the transportation, the bait is stopped, and...

Embodiment 2

[0007] Example 2: On August 31, 2011, fish fry from an indoor cement pond in the Fengxian Seed Technology Center Base of Shanghai Fisheries Research Institute were transported to a cement pond in downtown Shanghai. The netting exercise is the same as before. After pulling the net, shake the fry in the net enclosure with a scoop into a small cage prepared in advance for 15-30 minutes. The size of the net cage is 120cm×60cm×45cm. , The mesh is a polyethylene net of 20 meshes, so that the fry can adapt to the environment of a small water body first, and then bagged for transportation. The transport container used is a fry bag. The size of the fry bag is 25cm×20cm×30cm. The volume is about 15 liters. Scoop the temporarily reared fry into a fry bag with a water scoop or a basin with fry and water. Fill the bag with about 5 liters of water. The number of fry to be shipped is controlled at about 50, that is, about 5 per liter. , After the fry is bagged, fill it with pure oxygen until ...

Abstract

The invention relates to a transfer technique of indoor bred Yangtze River Coilia ectenes summer fingerlings, belonging to the field of live fish transportation. The transfer technique consists of steps of net hauling for exercise, net hauling operation and transportation. The transfer technique is characterized in that net hauling for exercise is conducted to the fingerlings before transportation; feeding is forbidden one day before transportation, net hauling operation is conducted to gather the fingerlings in a net enclosure, the fingerlings are scooped into a transportation tool by using a water ladle or a basin and the fingerlings are guaranteed not to leave water during operation; the transportation is divided into short-distance transportation and long-distance transportation according to transportation duration, the duration of short-distance transportation is controlled to be 30-40 minutes, containers for containing the fingerlings for short-distance transportation are plastic barrels, the quantity of fingerlings in each barrel is controlled to be 100-200 and the water temperature is controlled to be 28DEG C; and the duration of long-distance transportation is controlled to be 4-5 hours, the fingerlings in the net enclosure are scooped into a small net cage for temporary culture for 15-30 minutes by using the water ladle after net hauling is conducted, then the fingerlings are contained in bags for transportation, five liters of water and 50 fingerlings are contained in each bag, the bags which contain the fingerlings are contained in black thin film bags to prevent irritation of strong light, and the water temperature is controlled to be below 28DEG C.

Description

Technical field [0001] The invention relates to the transportation of live fish, in particular to the transportation technology of the summer flower fingerlings bred indoors of the Yangtze River Coilia. Background technique [0002] Coilia ectenes (Coilia ectenes) belongs to the genus Herringoides, Anchovy and Coilia, commonly known as saury, saury, hairy saury, beard fish, coilia, etc. It is mainly distributed in the Yellow Sea and the East my country Sea. It can be seen in all the rivers that open to the sea, such as the Liao River, Haihe River, Yellow River, Yangtze River and Qiantang River. It is known for its tender meat and delicious taste. It is one of the "Three Fresh Yangtze Rivers". The precious migratory fish. In recent years, due to the influence of many factors such as overfishing and the deterioration of the ecological environment, the Coilia spp. resources have declined sharply, but the market demand has increased unabated, and even reached the dilemma of priceless...
