Abstract

Provided is a method for rearing Artemias in a feeding water tank, wherein a feed containing a mollusk-derived feed is poured into the feeding water tank. Provided is a feed for Artemia that contains a mollusk-derived feed. Provided is an Artemia which satisfies at least one of the following requirements at 6 days of age: body width being greater than 0.183 mm; body height being greater than 0.179 mm; and volume greater than 0.099 mm 3 .

Claims (16)

1 . A method for cultivating Artemia in a rearing tank, the method comprising:

providing a feed into the rearing tank, wherein individuals of the Artemia have been placed into the rearing tank,

wherein the feed comprises (i) glycogen at a content from 1.1 mass % to 27.6 mass % on a total amount basis, (ii) zinc at a content from 5.0×10 −3 mass % to 251.1×10 −3 mass % on a total amount basis, (iii) taurine at a content from 0.01 mass % to 6.9 mass % on a total amount basis; and (iv) protein at a content from 38.7 mass % to 88.4 mass % on a total amount basis, and

wherein the feed is provided into the rearing tank from 0 days old after hatching.

2 . The method for cultivating Artemia according to claim 1 ,

wherein the feed comprises a mollusk-derived feed.

3 . The method for cultivating Artemia according to claim 2 , wherein the mollusk-derived feed comprises a mollusk-derived component in an amount of 5 mass % to 100 mass %.

4 . The method for cultivating Artemia according to claim 2 , wherein the mollusk-derived feed is a shellfish-derived material.

5 . The method for cultivating Artemia according to claim 2 , wherein the mollusk-derived feed is a powder.

6 . The method for cultivating Artemia according to claim 2 , wherein the mollusk-derived feed comprises particles, and the particles have an average particle size of 10 μm to 300 μm.

7 . The method for cultivating Artemia according to claim 1 , wherein the feed is provided into the rearing tank until the Artemia is 25 days old.

8 . The method for cultivating Artemia according to claim 1 ,

wherein the feed is derived from a mollusk selected from the group consisting of Solenogastres, Caudofoveata, Polyplacophora, Monoplacophora, Bivalvia, Scaphopoda, Gastropoda, and Cephalopoda.

9 . The method for cultivating Artemia according to claim 8 , wherein the feed is provided into the rearing tank until the Artemia is 25 days old.

10 . The method for cultivating Artemia according to claim 8 , wherein the feed comprises a mollusk-derived component in an amount of 5 mass % to 100 mass %.

11 . The method for cultivating Artemia according to claim 8 , wherein the feed comprises particles, and the particles have an average particle size of 10 μm to 300 μm.
