Abstract
Abstract A method of spawning, collecting, hatching and shipping shrimp by controlling the selection of spawned eggs to obtain only the most desirable, and placing the desired eggs into a hatching tank for hatching. The shrimp are then hatched, the nauplii shrimp collected and placed into a shipping container. The temperature of the water in which the nauplii shrimp are shipped is maintained in a predetermined range to control the growth of the shrimp so they do not progress beyond the beginning of the protozoeal stage of growth during the shipment thereof.

Independent Claim
118 words
A method of spawning, hatching and shipping nauplii shrimp comprising the steps of: placing gravid female shrimp into spawning tanks; retaining the gravid female shrimp in the tank for a period of time sufficient for the eggs to be spawned; collecting the spawned eggs from the tanks; hatching the spawned eggs to obtain a nauplii shrimp; collecting the nauplii shrimp; placing the nauplii shrimp into a shipping container and controlling the temperature of the sea water during the shipment of the nauplii shrimp to prevent the shrimp from progressing beyond the beginning of the protozoeal stage of growth during the shipment thereof and thereafter acclimating the shrimp in sea water under desired conditions for the subsequent growth thereof.
