Abstract

The invention discloses an alga control method for a conch filament culture process of Porphyra haitanensis. The method comprises the following steps: (1) selecting and treating of conches: selecting a proper quantity of Monodonta labio with the weight of 2.5g to 3.0g, and carrying out surface treatment for 4 to 6 minutes by a potassium permanganate solution with the concentration of 0.6*10<5>g / ml to 1.5*10<5>g / ml before stocking; (2) conch stocking: carrying out Monodonta labio stocking when obvious alga attachment is present on surfaces of breeding conches; (3) alga clearing stage: in first 4 to 7 days after Monodonta labio stocking, carrying out Monodonta labio manure disposal at least once every day; (4) maintenance stage: 4 to 7 days after Monodonta labio stocking, carrying out Monodonta labio manure disposal once every other day; and (5) conch recovery: recovering Monodonta labio before conch filaments are subjected to photo-stimulated ripening. The method is simple and practical and is remarkable in effect, hybrid algae generated from the conch filament culture process of the Porphyra haitanensis are effectively removed, and the successful culture of the conch filaments of the Porphyra haitanensis is guaranteed.

Description

technical field

[0001] The invention relates to the technical field of biological control, in particular to a method for preventing and controlling attached algae organisms during the cultivation process of seaweed shell filaments. Background technique

[0002] Altar laver is an important economic seaweed in my country, and its output accounts for more than 80% of the national laver output. In recent years, with the rapid development of algae cultivation and processing scale, it has become the leading industry of seaweed in coastal provinces such as Zhejiang and Fujian. In the cultivation process of algae laver, the cultivation of shell filaments is very important. The quality of this process is directly related to the seed supply of algae laver in the later stage, which in turn has a decisive effect on the cultivation area and output.

[0003] The altar seaweed shell filament cultivation stage is generally from March to mid-July. During this period, the shell filaments hav...
