Abstract

The invention provides a Caulerpa lentillifera cultivation pond. The pond comprises a pond body, a plurality of partitions and attachments; the length of each partition is smaller than the width of the pond body, and water-passing ports are formed by the partitions and the side walls of the pond body; the partitions are mounted in the pond body in parallel at staggered intervals, and the pond body is divided into multilevel water-passing channels; a water inlet tube is arranged above the first-level water-passing channel formed by the partition and the side walls of the pond body; an overflow water outlet tube is arranged in the water-passing channel of the last level; the attachments are laid in the water-passing channels. The invention further discloses a cultivation method making use of the above Caulerpa lentillifera cultivation pond. According to the pond and the method, on the basis of the natural growth environment of Caulerpa lentillifera, through arrangement of the partitions in the cultivation pond in staggered parallel which form the water-passing ports with the corresponding walls of the cultivation pond, the water-passing channels are formed, and the water inlet tube and the overflow water outlet tube are arranged at the head and tail ends of the cultivation pond respectively, so that convenience is brought to simulation of the ocean current flowing conditions of Caulerpa lentillifera cultivation, Caulerpa lentillifera growth is promoted, and the product quality is improved.

Description

technical field [0001] The invention belongs to the technical field of aquaculture, and relates to a long-stem grape fern algae culture pond and a culture method. Background technique [0002] Botrytis longstem is a kind of nutrient-rich edible green algae belonging to the family Chlorophyta Pteridaceae. It grows naturally in the Palau Islands and Jigport Islands in the Pacific Ocean with Okinawa as the northern line. Because the shape of Vitis vinifera is crystal clear and plump like grapes, it is called sea grape, because it is rich in seaweed polysaccharides, collagen and dietary fiber, the composition of amino acids is balanced and complete, and the fat content is low and mostly unsaturated fatty acids. Rich in minerals and vitamins, the taste is as rich and juicy as caviar, and it is also known as "green caviar". [0003] Due to the rich nutrition and excellent palatability of Botrytis elongatus, the market demand for this algae has increased rapidly, and the price is ...
