A device for sampling and observing buried shellfish juvenile shellfish and methods for making and using the same

Abstract

The invention relates to a device for sampling and observation of buried habitat type shellfish juvenile mollusk and a manufacturing and using method thereof. The device comprises a sampling pipe, a filter sieve and an observation plate. The sampling pipe is a PVC water supply pipe. The filter sieve comprises a PVC water supply pipe, screen cloths and a PVC water supply sleeve. The inner side of the PVC water supply sleeve is provided with the PVC water supply pipe. The PVC water supply sleeve and the middle and the upper end of the PVC water supply pipe are provided with the screen cloths, the observation plate comprises a culture dish and a black plastic film. The black plastic film is arranged at the lower end of the culture dish and used for facilitating observation. The device has the advantages that juvenile mollusk adhering to the bottom of a culture pool can be taken out at any time, substrate is removed quickly, clean juvenile mollusk free of impurities is obtained, observation of juvenile mollusk activity, ingestion and growth conditions is facilitated, juvenile mollusk growth and feeding conditions and water quality are analyzed, effective help is provided for water replacement, juvenile mollusk transfer and pool pouring, and classified culture and the like, culture management is convenient, and the device saves time and labor and has good application prospect.

Description

technical field [0001] The invention belongs to the technical field of artificial breeding of aquatic products, and in particular relates to a device for sampling and observing buried shellfish juvenile shellfish and methods for making and using the same. Background technique [0002] The large-scale indoor artificial breeding of shellfish mainly started in the 1970s in my country, and has been researched and popularized for nearly 50 years. Some important economic species, such as scallops, oysters, meretrix meretrix, Philippine clams, cockles, razor clams, pearl oysters, abalones, etc., have basically formed a system for promoting maturation of shellfish, induced egg collection, fertilization and hatching, selection and planktonic larvae. A relatively complete set of technical specifications for seedling production such as cultivation, spat cultivation, and intermediate cultivation of seedlings. The main technical links of industrialized shellfish breeding in foreign coun...

Problems solved by technology

[0006] The technical problem to be solved by the present invention is to provide a device for sampling and observing buried shellfish juveniles and its production and use method. By using the device, it can be attached to the seedling pond at any time during the production of buried shellfish artificial seedlings. Sampling and observation of spat in the bottom attachment substrate, grasping the feeding situation and vigor of spat in a timely manner, and taking corresponding technical measures through shellfish behavior observation, to solve the problem that the hardware and software technology for visual tracking observation is not yet mature, and the usual practice The most important thing is to increase the frequency of pool inversion. Generally, it takes 3 to 5 days to invert the pool. The workload is quite heavy. In addition, the initial supporting work such as the disinfection of the attachment base and the insertion of the attachment base into the mud is time-consuming and laborious, and sometimes the best rescue is missed. a matter of bei ' s timing
