BACKGROUND
[0002] As a large vessel aquaculture facility, an aquaculture working vessel can well solve the problem of water pollution caused by long-term fixation of traditional cage culture in a certain water area due to its flexible mobility. Moreover, the aquaculture working vessel may transfer the aquaculture area in time before a severe weather comes. Compared with the traditional cage aquaculture, the biggest difference is that the aquaculture working vessel processes an aquaculture fishroom with a fixed steel structure.
[0003] When growing to a mature period, a cultured fish body may be caught. The traditional cage culture is that an adult fish is caught again by adopting a brail net or a fish pump and other methods after a mature fish school (hereinafter referred to as the adult fish) in the whole net cage is usually collected in a manner of integrally lifting the net cage or shrinking a netting gear. Through this method, a certain extrusion will be caused to the fish body due to the extrusion of a great number of fish schools, a great fish school density will easily cause a great number of fish schools to suffocate, and this method cannot catch fish selectively but only catch all fishes in the net cage.

en het heffen van het visverzamelframe en het verplaatsen van het visverzamelframe naar een reservoirpositie, met behulp van een visaanzuigpomp op het aquacultuurwerkvat om de volwassen vis door een visaanzuigpomp te vangen, en het automatisch te tellen en te wegen;Method for a fish moving and catching device suitable for a migratory fish and in an aquaculture work vessel according to any one of claims 1-7, comprising the following steps: S1: preparatory work: taking a school of fish to be moved as a starting aquaculture fishroom within an aquaculture fishroom, and selecting an aquaculture fishroom adjacent to the starting aquaculture fishroom as a target aquaculture fishroom; transferring a fish collecting frame in the target aquaculture fish room to an output of the fish moving device by a lifting device, opening an output opening on the bottom of the fish collecting frame, reducing the water level height in the target aquaculture fish room, so that it fish collecting frame is lower than the output of the fish moving device; reducing the water level height in the starting aquaculture fish room so that the water level just reaches a position of an input end cover of the fish moving device; regulating a regulation device of a stair slide based on the habit of the farmed fish, regulating a migrating phase to a stair shape, regulating a sliding phase to the slide, and separately adjusting an appropriate angle of each regulation device in the migrating phase, to achieve the best migrating angle and speed; and regulating the water discharge amount of the drain opening based on the water input flow, so that the water discharge amount is consistent with the water input amount to avoid excessive water absorption from flooding the slide; S2: guiding migration: opening an input end cover and an output end cover of the fish moving device, and guiding the adult fish school to migrate independently along the fish moving device; in order to prevent the sliding of an adult fish due to lack of physical strength, lifting the regulator of the stair slide as required, so that the adult fish migrates to a buffer pool of a buffer stage many times; spraying a water inlet at the top of a buffer section with a stream of water at a suitable pressure to flush the adult fish into the sliding phase, and sliding the adult fish from the fish collection frame by gravity into the target aquaculture fish enclosure, when some of the adult fish in the fish collecting frame reaches a sufficient number, closing the input end cover of the fish moving device, and closing the output opening on the bottom of the fish collecting frame; and lifting the fish collecting frame and moving the fish collecting frame to a reservoir position, using a fish suction pump on the aquaculture work vessel to catch the adult fish by a fish suction pump, and counting and weighing it automatically; S3: herhaalde geleiding: na het aanzuigen van de volwassen vis in het visverzamelframe, het wederom verplaatsen van het visverzamelframe naar de uitvoer van de inrichting voor het verplaatsen van vis, het herhalen van de bovenstaande S2, het openen van de invoereindebedekking en het ononderbroken geleiden van de volwassen vis in de startende aquacultuurvisruimte om te migreren totdat er geen volwassen vis meer is om te migreren; enS3: repeated guiding: after sucking the adult fish into the fish collecting frame, moving the fish collecting frame again to the output of the fish moving device, repeating the above S2, opening the input end cover and continuous guiding of the adult fish in the starting aquaculture fish room to migrate until there are no more adult fish to migrate; and S4: het beëindigen van werk: nadat de volwassen vis voor de laatste keer in het visverzamelframe aangezogen is, het verplaatsen van het visverzamelframe naar een hoek van de hefinrichting, en het vergrendelen van het visverzamelframe; het sluiten van een waterinvoerklep in de inrichting voor het verplaatsen van vis en het omhoog vouwen van de waterinvoer, het neerlaten van de aanpasbare glijbaan, het sluiten van de afvoeropening, en ten slotte het neerlaten van de invoereindebedekking en de uitvoereindebedekking van de inrichting voor het verplaatsen van vis; en het herstellen van de aquacultuurwaterniveauhoogtes van de startende aquacultuurvisruimte en de doel-aquacultuurvisruimte.S4: finishing work: after the adult fish has been sucked into the fish collecting frame for the last time, moving the fish collecting frame to a corner of the lifting device, and locking the fish collecting frame; closing a water inlet valve in the fish moving device and folding up the water inlet, lowering the adjustable slide, closing the discharge opening, and finally lowering the inlet end cover and the outlet end cover of the fish transfer device moving fish; and restoring the aquaculture water level elevations of the starting aquaculture fish room and the target aquaculture fish room.
