Embodiment 1

[0022] The method for ecologically breeding the pufferfish seedlings in a breeding pond of the dark-patterned puffer of the present invention comprises the steps of pond preparation, stocking of the puffer parents, inoculation of cladocerans and copepods, stocking of the black-patterned puffer, feeding of bait, and brooding of eggs. The production steps of shrimp stocking, daily management, pulling nets and catching, including:

[0023] 1) Pond preparation: choose an earthen pond with a flat bottom. The pond is preferably 2m deep, 1.5m water level, and 2.5-5.0 mu in area; each pond is equipped with 1-2 1.5kw aerators, and the water inlet is covered with double layers Filter the pond with 60-mesh sieve mesh bag, and use 300-400 catties / mu of quicklime to spray and disinfect the pond. After the pond has been disinfected for 2 days, it will be soaked in water until the bottom of the pond is submerged. After soaking for 48 hours, it will be completely drained and exposed to the sun ...

Embodiment 2

[0033] Using the above method of the present invention, in 2016, at the 58th Research Base of Fengxian Research Base of Shanghai Fisheries Research Institute # The pond covers an area of ​​4 mu. On April 12, 350 local wild puffer fish were stocked; on April 29, 2,100 puffer fish were raised; on November 15, 1,810 puffer parents were obtained, which survived The rate was 86.2%. There were 325 scorpionfish parents, with an average size of 56.3g in weight and 25.0cm in length. The survival rate was 91.14%, and the unit yield was 9.15 jin / mu. On the second day, the net was pulled, and a total of 2,000 scutellaria seedlings were obtained. The average size of the tail is 6.8g in weight and 12.6cm in length, and the unit output is 500 tails / mu.

Embodiment 3

[0035] Using the above method of the present invention, in 2018, in 2 middle schools of Fengxian Scientific 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 fish fingerlings of the dark-patterned oriental puffer, the stocking density was 1,000 fish / mu, and the size was 136.6g / tail; 500 first-year fish were stocked; November 7 The net was drawn to obtain 2,130 commercial fish with dark stripes, 362.3g / tail, with a survival rate of 85.2%, and 290 saury parents, with an average size of 33.93g in weight and 21.09cm in length, with a survival rate of 58.00% and unit output. 7.87 catties / mu; accumulatively obtained 1,878 scallops, with an average size of 11.18g in weight, 14.60cm in length, and a unit output of 751 / mu.

Abstract

The invention relates to the technical field of aquaculture, in particular to a method for ecologically breeding coilia nasus schlegel fries in a takifugu obscures culture pond, which comprises eightsteps of pond preparation, stocking of coilia nasus schlegel parents, inoculation of cladocerans and copepods, stocking of takifugu obscures, bait feeding, stocking of brooding freshwater shrimps, daily management, and net pulling for catching. The invention fully utilizes the water space of a takifugu obscurus parent culture pond, increases yield of the adult coilia nasus schlegel and large-sizedfries under the conditions of not increasing the input and not reducing the takifugu obscures parent culture density, improves the water utilization rate of the pond, improves the economic benefit, makes the water quality of the pond more stable, improves the feed utilization rate, and reduces the takifugu obscures culture cost; the method of the invention is easy to operate and can be easily accepted and promoted.

Description

technical field [0001] The invention relates to the technical field of aquaculture, in particular, to a method for ecologically breeding scutellaria fry in a pufferfish culture pond with dark stripes. Background technique [0002] Oriental puffer (Takifugu), commonly known as puffer fish, belongs to pufferfish order, puffer suborder, puffer family, eastern puffer. Its muscles are white as cream, the meat is delicious, fresh and delicious, rich in protein and rich in nutrients, and it is known as the first of the "three fresh foods in the Yangtze River". my country has a traditional habit of eating puffer fish since ancient times, especially in Jiangsu and Zhejiang areas, puffer fish has always been regarded as a treasure on the table. Pufferfish toxin can be extracted from the liver and ovary of puffer fish, which has high economic and medicinal value, and has broad prospects for foreign exchange earning. In September 2016, the General Office of the Ministry of Agriculture...
