Tóm tắt

Bài tổng quan này cung cấp cái nhìn tổng quát về các khía cạnh sinh thái của tảo vĩ mô trôi nổi và tảo cát liên quan đến việc sử dụng thương mại hiện tại và tiềm năng của nguồn tài nguyên này ở Australia. Bài viết bắt đầu với các phần nói về những ngành công nghiệp sử dụng tảo vĩ mô và cỏ biển, sinh thái của các hệ sinh thái bờ biển và gần bờ, cũng như quy trình lắng đọng của tảo vĩ mô và cỏ biển trên bãi biển. Sau đó, bài viết mô tả những loài tảo vĩ mô và cỏ biển kinh tế chính xuất hiện như rác biển dạt vào bờ, với mục tiêu nhấn mạnh thông tin đã biết về phân bố môi trường sống, phạm vi địa lý và các vấn đề thu hoạch. Những khoảng trống trong kiến thức khoa học đã được chỉ ra. Các lĩnh vực ưu tiên cho nghiên cứu trong tương lai được xác định như sau: • Tầm quan trọng của việc tích tụ tảo vĩ mô và cỏ biển trên việc cho ăn và làm tổ của các loài chim ven biển; • Việc tài nguyên có sẵn có cho phép thu hoạch bền vững về sinh thái và kinh tế không; • Một khảo sát về tảo vĩ mô và cỏ biển thương mại hiện tại và tiềm năng: nghiên cứu sinh khối, mật độ và tỷ lệ sản xuất hàng năm, sự biến đổi giữa các năm trong việc tái sinh vào các quần thể sống, tác động của việc thu hoạch lên động lực học và cấu trúc cộng đồng, và sự ổn định của cơ sở tài nguyên cho việc thu hoạch bền vững về kinh tế; • Đánh giá tầm quan trọng của rác biển trong việc tái chế chất dinh dưỡng và mùn cho các hệ sinh thái ven biển gần bờ ở quy mô địa lý rộng lớn hơn những nghiên cứu trước đây. Nghiên cứu này nên đánh giá sự phụ thuộc của sản xuất ngoài khơi vào chất dinh dưỡng và mùn được phân hủy trong rác biển.
