Abstract
Abstract Method and package for storing marine larvae, such as oyster larvae, by taking marine larvae at or near the state of metamorphosis and reducing the marine larvae to a temperature substantially below the larval growing temperature to avert metamorphosis for a period of time, and thereafter raising the temperature of the marine larvae to cause metamorphosis to commence.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
99 words
In the method of storing oyster larvae, causing oyster eggs to form into free swimming oyster larvae in sea water, causing the free swimming oyster larvae to grow until they are at or near the state of metamorphosis, reducing the temperature of the free swimming oyster larvae to a temperature substantially below the larval growing temperature to avert metamorphosis in the larvae and storing the larvae at said temperature below the larval growing temperature for a period of time to permit shipment of the oyster larvae before they have reached metamorphosis and before they have attached themselves to cultch.
Claim 2
Dependent Claim
99 words
In the method of storing oyster larvae, causing oyster eggs to form into free swimming oyster larvae in sea water, causing the free swimming oyster larvae to grow until they are at or near the state of metamorphosis, reducing the temperature of the free swimming oyster larvae to a temperature substantially below the larval growing temperature to avert metamorphosis in the larvae and storing the larvae at said temperature below the larval growing temperature for a period of time to permit shipment of the oyster larvae before they have reached metamorphosis and before they have attached themselves to cultch.
Claim 3
Dependent Claim
33 words
A method as in claim 1 together with the step of thereafter raising the temperature of the oyster larvae to cause metamoRphosis of the larvae and their attachment to the cultch to commence.
Claim 4
Dependent Claim
29 words
A method as in claim 1 wherein said method is carried out in sea water and wherein said oyster larvae are stored in a reduced volume of sea water.
Claim 5
Dependent Claim
20 words
A method as in claim 1 wherein said method is carried out by storing the oyster larvae exposed to air.
Claim 6
Dependent Claim
24 words
A method as in claim 1 wherein said oyster larvae are reduced to a temperature ranging from slightly above 0* C. to 15* C.
Claim 7
Dependent Claim
16 words
A method as in claim 2 wherein the temperature is raised from 20* to 32* C.
Claim 8
Dependent Claim
34 words
A method as in claim 1 together with the step of placing a reduced volume of sea water containing the oyster larvae in a water-tight vessel and retaining the vessel at the reduced temperature.
Claim 9
Dependent Claim
30 words
A method as in claim 4 together with the step of placing the oyster larvae in a water-tight vessel having air therein with a relative humidity close to 100 percent.
Claim 10
Dependent Claim
20 words
A method as in claim 4 wherein said oyster larvae are disposed in a cloth carried in a water-tight vessel.
