Abstract
【解決手段】造成用基盤1に保護網4などの多孔状の保護カバーで囲んでカバー内の海藻を藻食性魚類から永続的に保護する保護空間を設けるとともに、藻食性魚類の侵入を阻止する一方、アワビやサザエ等の匍匐性水産生物のカバー内への進入を許容する通用部を設けて、前記保護カバー4内をアワビ6やサザエ等の藻食性の匍匐性水産生物に対する餌料場として提供する。
【選択図】図1
Description
(1)保護カバーにより囲まれた保護空間内の移植用海藻種苗や自然着生した生長過程の海藻及びそれらの生長海藻は、摂食圧の大きい藻食性魚類の食害から確実かつ永続的に保護される。
(2)したがって、藻場造成上の確実性が大幅に向上されるとともに、造成後には、前記保護カバーによって囲まれた保護空間内の海藻が核として機能し、藻場の永続性にもきわめて有効である。
(3)前記保護カバーにより囲まれた保護空間は、アワビやサザエ等の藻食性水産生物に対する餌料場として提供されることから、水産上きわめて有効である。
Claims (6)
- 造成用基盤に保護網などの多孔状の保護カバーで囲んで藻食性魚類から保護する海藻の保護空間を設けるとともに、藻食性魚類の侵入を阻止する一方、アワビやサザエ等の匍匐性水産生物のカバー内への進入を許容する通用部を設けて、前記保護カバー内を藻食性の匍匐性水産生物の餌料場として提供することを特徴とする藻場造成方法。

- 造成用基盤に保護網などの多孔状の保護カバーで囲んで藻食性魚類から保護した海藻の保護空間を設けるとともに、藻食性魚類の侵入を阻止する一方、アワビやサザエ等の匍匐性水産生物の前記保護カバー内への進入を許容する通用部を設けたことを特徴とする藻場造成用構造物。
- 前記保護カバー内に移植用海藻種苗を設置したことを特徴とする請求項3に記載の藻場造成用構造物。
- 前記通用部を造成用基盤と保護カバーとの間の間隙によって形成したことを特徴とする請求項3又は4に記載の藻場造成用構造物。
- 前記造成用基盤に前記匍匐性水産生物の通過可能な通路を形成したことを特徴とする請求項3〜5のいずれか一項に記載の藻場造成用構造物。
