Problems solved by technology

[0002] Fry transportation is a necessary step to transport fry from one place to another for growth, and it is also the first step in the growth of fry. Fry transportation is very important in aquaculture production, because compared with adult fish, fry are small in size and vigorous in vitality. Weak, poor resistance to stress and disease, easy to die during transportation, resulting in low survival rate of fry;
[0003] There are certain disadvantages in the existing fish fry transportation method. First of all, the fish fry are usually not stopped feeding during the traditional fish fry transportation, which leads to unclean removal of the feces in the fry body, and it is easy to pollute the water quality due to discharge into the transport container, reducing the life expectancy of the fry. Anti-stress ability, secondly, a traditional nylon film bag is used to pack fish, and it is easy to cause water leakage and air leakage due to the low strength of packaging fish, which cannot better provide conditions for the survival of fry. Finally, The tightly tied nylon film bags are directly packed into cartons or foam boxes, which are easy to be crushed and broken due to external pressure. Therefore, we propose a method for fry transportation

Embodiment 1

[0028] (1) Fry stop feeding treatment: choose healthy, disease-free and non-injured fry, strictly use a sieve to screen the fish species when selecting fry, remove wild fish, ensure consistent specifications, raise them in new water one day in advance, and stop feeding;

[0029] (2) Bag selection: Select a 70×40cm nylon film plastic bag, check for air leakage, open the bag mouth, and quickly pinch the bag mouth tightly from top to bottom to keep the air in the bag in a bulging state, and then use another Press the bag with only one hand to see if there is any air leakage;

[0030] (3) Fill the fish with water: fill the bag selected in step (2) with moderate water, generally fill each bag with 1 / 4 of water, and put the fish selected in step (1) into the inner bag, and fill the fish according to the calculation Lightly pack the fry into bags, and ship 800 fish fingerlings with a length of 5-7 cm and 500 fingerlings with a length of 8-9 cm. The water used for transporting fry is ...

Embodiment 2

[0036] (1) Fry stop feeding treatment: choose healthy, disease-free and non-injured fry. When selecting fry, strictly use a sieve to sieve the fish species, remove wild fish, ensure consistent specifications, and raise them in new water 1.5 days in advance, and stop feeding;

[0037] (2) Bag selection: Select a 70×40cm nylon film plastic bag, check for air leakage, open the bag mouth, and quickly pinch the bag mouth tightly from top to bottom to keep the air in the bag in a bulging state, and then use another Press the bag with only one hand to see if there is any air leakage;

[0038] (3) Fill the fish with water: fill the bag selected in step (2) with moderate water, generally fill each bag with 1 / 3 of water, put another bag of the same specification outside the nylon film bag, and put it into the inner bag. For the fish selected in (1), according to the calculated amount of fish, put the fry into the bag briskly, and ship 700 fish fingerlings with a length of 5-7 cm and 400...

Embodiment 3

[0044] (1) Fry stop feeding treatment: choose healthy, disease-free and non-injured fry. When selecting fry, strictly use a sieve to screen the fish species, remove wild fish, and ensure consistent specifications. Keep them in new water 2 days in advance and stop feeding;

[0045] (2) Bag selection: Select a 70×40cm nylon film plastic bag, check for air leakage, open the bag mouth, and quickly pinch the bag mouth tightly from top to bottom to keep the air in the bag in a bulging state, and then use another Press the bag with only one hand to see if there is any air leakage;

[0046] (3) Fill the fish with water: fill the bag selected in step (2) with moderate water, generally fill each bag with 1 / 2 of water, put another bag of the same specification outside the nylon film bag, and put it into the inner bag. For the fish selected in (1), according to the calculated amount of fish, put the fry into the bag briskly, and transport 600 fish fingerlings with a length of 5-7 cm and 3...

Abstract

The invention discloses a fry transportation method. The fry transportation method comprises the following specific steps of fry indigestion treatment, wherein healthy and strong fries free of diseases and wounds are selected and are raised in water 1-2 days in advance, and feeding is stopped; bag selection, wherein nylon film plastic bags of 70 cm*40 cm are selected. According to the fry transportation method, during fry indigestion treatment, all the excrement in the bodies of the fries can be discharged, the metabolic rate of the fries is reduced, it is avoided that the excrement is discharged into a transportation container to contaminate water, and the anti-stress ability of the fries is enhanced; when water is injected to put the fries in, the nylon film plastic bags are covered withbags of the same specification, the strength of fry packaging is improved, water leakage and air leakage caused by loose packaging are avoided, and better conditions are provided for survival of thefries; when the bags are tied and boxed, the tightly tied nylon film bags are placed in woven bags and then placed in cartons or foam boxes, the strength achieved after tight tying is carried out canbe guaranteed, extrusion caused by external pressure is buffered, bag mouths are prevented from cracking, and better use prospects are brought.
