Method for culturing cyprids of balanus reticulates on large scale

Abstract

The invention discloses a method for culturing cyprids of balanus reticulates on a large scale, which comprises the following steps: after ovum of the balanus reticulates is bred into naupliar larva, putting the naupliar larva into a culture medium with bait for constant temperature culture in dark environment; performing intermittent lighting on the naupliar larva in the constant temperature culture process; and performing cold storage on the appeared cyprids. The method can overcome the defects of high death rate, small and unstable yield, quick settlement and metamorphosis processes, incapacity of storage and accumulation and the like in the breeding process of the cyprids, greatly improve the yield of the cyprids, effectively prolong the time of a drifting stage of the cyprids, promotethe settlement synchrony of the cyprids, and provide required experimental materials for screening marine fouling organism antifouling compositions and studying environmental toxicology, along with wide application prospect.

Description

technical field

[0001] The invention belongs to the field of biotechnology, and relates to a method for cultivating netted barnacle Venus larvae in large quantities. Background technique

[0002] Marine fouling organisms are the general term for animals, plants and microorganisms that inhabit or attach to ships and various underwater artificial facilities in the marine environment, adversely affect human economic activities, and bring negative benefits to investors . The attachment of fouling organisms to the ship will reduce the speed of the ship, reduce the inner diameter of the pipeline, change the metal corrosion process, and even cause the navigation mark to shift; the attachment to the aquaculture facility will occupy the effective attachment surface of some aquaculture objects, hindering the net cage. The exchange of internal and external water bodies affects the growth and development of the cultured objects; and some species (such as barnacles) have strong adhesion...
