Embodiment 1

[0022] This embodiment is aimed at seawater with few nutrients in water and low density of unicellular algae.

[0023] (1) In the spring of the first year, when the seawater temperature is 3°C, put 100 kilograms of semi-finished blue mussels with a size of 4 cm in the sea cucumber culture pond, so that the density of single-celled algae in the culture pond can be controlled at 30,000 to 50,000 per unit. ml;

[0024] (2) As the seawater temperature rises slowly, when the seawater temperature rises to 17°C, the semi-finished blue mussel has grown into a finished product. At this time, 70% of the finished blue mussel is taken out, and the remaining 30% of the blue mussel is left shellfish products;

[0025] (3) drop into the gulf scallop seedling that specification is 3mm again in the culture pond, drop 1 kilogram in every mu, so that the density of unit cell algae in the culture pond is controlled at 3~50,000 / ml;

[0026] (4) In winter, when the seawater temperature dropped to...

Embodiment 2

[0031] This embodiment is aimed at seawater with rich water quality and high density of single-celled algae.

[0032] (1) In spring, when the seawater temperature was 7°C, 200 kilograms of semi-finished blue mussels with a size of 5 cm were dropped into the sea cucumber culture pond, so that the density of unicellular algae in the culture pond was controlled at 30,000 to 50,000 / ml;

[0033] (2) As the seawater temperature rises slowly, when the seawater temperature rises to 23°C, the semi-finished purple mussel has grown into a finished product. At this time, 60% of the finished blue mussel is taken out, and the remaining 40% of the blue mussel is left shellfish products;

[0034] (3) drop into the gulf scallop seedling that specification is 5mm again in the culture pond, drop 0.8 kilogram in every mu, so that the density of unit cell algae in the culture pond is controlled at 3~50,000 / ml;

[0035] (4) In winter, when the seawater temperature dropped to 7°C, the bay scallop s...

Embodiment 3

[0040] This embodiment is aimed at seawater with general water quality.

[0041] (1) In spring, when the seawater temperature was 5°C, 150 kilograms of blue mussel semi-finished products of 4 cm were dropped into the japonicus culture pond, so that the density of single-celled algae in the culture pond was controlled at 30,000 to 50,000 / ml;

[0042] (2) As the seawater temperature rises slowly, when the seawater temperature rises to 20°C, the semi-finished purple mussel has grown into a finished product. At this time, 65% of the finished blue mussel is taken out, and the remaining 35% of the blue mussel is left shellfish products;

[0043] (3) drop into the gulf scallop seedling that specification is 4mm again in the culture pond, drop 0.9 kilogram per mu, so that the density of the unit cell algae in the culture pond is controlled at 3~50,000 / ml;

[0044] (4) In winter, when the seawater temperature dropped to 10°C, the bay scallop seedlings had grown into finished products,...

Abstract

The invention relates to a method for controlling the density of unicellular alga in a stichopus japonicus breeding pond. The method comprises the following steps: step one, in spring, Mytilus etilus semi-finished products are put into the breeding pond, so that the density of the unicellular alga in the breeding pond is controlled to between 30, 000 and 50, 000 per milliliter; step two, when thetemperature is increased to between 17 and 23 DEG C, part of the Mytilus etilus semi-finished products are taken out, and 30 to 40 percent of Mytilus etilus finished products in each mu are remained;step three, bay scallop seeds are put into the breeding pond, so that the density of the unicellular alga in the breeding pond is controlled to between 30, 000 and 50, 000 per milliliter; step four, when sea water temperature is reduced to between 8 and 12 DEG C, all bay scallop finished products are taken out; step five, in the next spring, the Mytilus etilus semi-finished products are put into the breeding pond, so that the density of the unicellular alga in the breeding pond is controlled to between 30, 000 and 50, 000 per milliliter; step six, when the sea water temperature is increased to between 17 and 23 DEG C, the remained 30 to 40 percent of the Mytilus etilus finished products from last year are completely taken out, and 42 to 67 percent of the Mytilus etilus finished products in the year are remained; and steps three to six are repeated.

Description

technical field [0001] The invention relates to a method for controlling the density of single-cell algae, in particular to a method for controlling the density of single-cell algae in a sea cucumber culture pond. Background technique [0002] The main food of sea cucumber is single-cell algae in seawater, and its normal growth environment is that the density of single-cell algae is 30,000-50,000 / ml. However, since there are only sea cucumbers in the japonicus culture ponds, the density of unicellular algae in the culture ponds must be maintained at 30,000-50,000 / ml so that the water must be changed every day, and the cost of cultivation is very high due to the large water changes every day. In addition, if the seawater cannot be replaced due to the small tidal range, or the salinity of the seawater outside the pond cannot be changed due to the rainy season, the unicellular algae in the sea cucumber culture pond will overgrow, sometimes reaching about 100,000 / ml. Excessive ...
