Problems solved by technology

Although the indoor full-artificial breeding technology of the Yangtze River Anchovy is becoming more and more perfect and mature, the production cost is still relatively high, and the labor cost is also relatively high. Although there are also ponds for ecological breeding of the Anchovy seedlings, it takes a lot of ponds

Embodiment 1

[0022] A method for ecologically breeding cuttlefish seedlings in a puffer fish breeding pond of the present invention comprises the steps of pond preparation, stocking of cuttlefish parents, inoculation of cladocera and copepods, stocking of pufferfish obscurus, bait feeding, and egg brooding Fresh shrimp stocking, daily management, pulling nets and other production steps, including:

[0023] 1) Pond preparation: Choose an earthen pond with a flat bottom, preferably with a depth of 2m, a water level of 1.5m, and an area of ​​2.5-5.0 mu; each pond is equipped with 1-2 1.5kw aerators, and the water inlet is double-layered Filter through a 60-mesh sieve with a tulle bag, and spray and disinfect the pond with 300-400 catties / mu of quicklime. After the pond is disinfected for 2 days, soak in water until it submerges the bottom of the pond. After soaking for 48 hours, drain and expose to the sun for later use;

[0024] 2) Stocking of the parent anchovy: usually in 3-4 months, select...

Embodiment 2

[0033] Adopt the above-mentioned method of the present invention, in 2016, in Fengxian scientific research base of Shanghai Fisheries Research Institute 58 # The pond covers an area of ​​4 mu. On April 12, 350 local wild anchovy were stocked; on April 29, 2,100 parents of Fugu obscurus were released; on November 15, the net was drawn, and 1,810 parents of Fugu obscurus were obtained and survived. The rate was 86.2%. There were 325 cuttlefish parents with an average weight of 56.3g and a body length of 25.0cm. The survival rate was 91.14%. tail, the average size is 6.8g in weight, 12.6cm in length, and the unit output is 500 tails / mu.

Embodiment 3

[0035] Using the above-mentioned method of the present invention, in 2018, in the 2nd of Fengxian Research Base of Shanghai Fisheries Research Institute # The pond covers an area of ​​2.5 mu. On April 19, there were 2,500 first-year-old puffer fish species, the stocking density was 1,000 fish / mu, and the size was 136.6g / tail; 500 first-year-old swordfish were stocked; November 7 Pulling the net, we obtained 2130 commercial fish of puffer obscurus, 362.3g / tail, with a survival rate of 85.2%, 290 parents of silver anchovy, with an average weight of 33.93g and body length of 21.09cm, with a survival rate of 58.00%, and the unit output It is 7.87 catties / mu; accumulatively obtained 1878 seedlings of anchovy, the average size is 11.18g in weight, 14.60cm in length, and the unit yield is 751 fish / mu.

Abstract

The present invention relates to the technical field of aquaculture, in particular to a method for ecological breeding of puffer anchovy seedlings in a culture pond of puffer anchovy, which consists of preparing ponds, stocking of puffer anchovy parents, inoculating cladocera and copepods, and puffer puffer obscurus inoculation. It consists of 8 production steps: stocking, bait feeding, stocking of oviposit freshwater shrimp, daily management, and netting. The present invention makes full use of the water body space of the puffer puffer culture pond, without increasing the input and without reducing the culture density of puffer puffer, increases the output of adult fish and large-sized seedlings of the puffer anchovy, and improves the quality of the pond. The utilization rate of the water body improves the economic benefit; the water quality of the pond is more stable, the utilization rate of the feed is improved, and the breeding cost of puffer puffer is reduced; the invention is easy to operate and easy to be accepted and popularized by people.

Description

technical field [0001] The invention relates to the technical field of aquaculture, in particular to a method for ecologically breeding cuttlefish seedlings in puffer puffer culture ponds. Background technique [0002] Fugu (Takifugu), commonly known as puffer fish, belongs to Fuguformes, Fugu suborder, Fuguidae, Fugu genus. Its muscles are as white as frost, the meat tastes plump, tender and delicious, rich in protein and rich in nutrition, and is known as the first of the "three delicacies of the Yangtze River". my country has had the traditional habit of eating puffer fish since ancient times, especially in Jiangsu and Zhejiang provinces, puffer fish has always been regarded as a treasure on the table. Tetrodotoxin can be extracted from the liver and ovary of puffer fish, which has high economic value and medicinal value, and has broad prospects for earning foreign exchange. In September 2016, the General Office of the Ministry of Agriculture and the State Food and Drug...
