Abstract

Disclosed herein is a feed composition that promotes the growth of zooplankton, enhances the survival rate of zooplankton, is safe, and has little adverse effect on the environment. The feed composition for zooplankton contains PHA.

First claim

1 - 4 . (canceled)

5 . A method for breeding zooplankton or shellfish, comprising:
feeding zooplankton or shellfish with a feed composition comprising PHA.

6 - 9 . (canceled)

10 . The method of claim 5 , further comprising:
feeding the zooplankton or the shellfish with an alga.

11 . The method of claim 10 , wherein the alga is at least one selected from the group consisting of an alga belonging to the genus Chlorella, an alga belonging to the genus Nannochloropsis, and an alga belonging to the genus Schizochytrium.

12 . The method of claim 5 , wherein the PHA is at least one selected from the group consisting of PHB, PHBH, and PHBV.

13 . The method of claim 5 , wherein the feed composition does not comprise EPA or DHA.

14 . The method of claim 5 , wherein the feed composition further comprises at least one selected from the group consisting of EPA, DHA, and DPA.

15 . The method of claim 5 , wherein the feeding comprises feeding the zooplankton with the feed composition.

16 . The method of claim 5 , wherein the zooplankton is at least one selected from the group consisting of a rotifer, an artemia, a copepod, and a water flea.

17 . The method of claim 5 , wherein the feeding comprises feeding the shellfish with the feed composition.

18 . The method of claim 10 , wherein the feed composition comprises the PHA and the alga such that the feeding of the feed composition and the feeding of the alga are performed at the same time.

19 . The method of claim 10 , wherein the feeding of the feed composition and the feeding of the alga are performed at different times.

20 . The method of claim 10 , wherein an amount of the PHA is 0.1 to 50 wt % with respect to a total amount of the PHA and the alga.

21 . The method of claim 5 , wherein the feeding is performed for a period of 2 days or more.

22 . The method of claim 5 , wherein the feeding is performed for a period of 3 to 7 days.

23 . The method of claim 22 , wherein during the period, the zooplankton or shellfish is fed with only the feed composition.

24 . The method of claim 22 ,
wherein the feed composition does not comprise EPA or DHA, and during the period, the zooplankton or shellfish is fed with only the feed composition.

25 . A method for promoting growth of zooplankton or shellfish, comprising:
administering zooplankton or shellfish with an agent comprising PHA as an active ingredient.

26 . The method of claim 25 , wherein the PHA is at least one selected from the group consisting of PHB, PHBH, and PHBV.

27 . A method for enhancing a survival rate of zooplankton or shellfish, comprising:
administering zooplankton or shellfish with an agent comprising PHA as an active ingredient.

28 . The method of claim 27 , wherein the PHA is at least one selected from the group consisting of PHB, PHBH, and PHBV.
