Harrisburg, Pennsylvania (October 27) -Penki Pennsylvania Fish and Shipbuilding Commission (PFBC) today announced that the GAP State Fish incubation field (SFHS) in the central county is based on specialThe response plan is operated.Incubate the house in the incubator to detect the invasion of New Zealand.
During the predetermined personnel training at Benne Spring SFH on May 31, 2022, the mud from New Zealand was found in the water supply pipeline in the building in the incubation site.It is important to note that although this is the first time in the PFBC incubation field, New Zealand has been discovered in New Zealand, these snails have been in Spring Creek, which has existed in Center County since 2010 and is adjacent to the Benner Spring facility.
The discovery of Benner Spring SFH prompted PFBC to immediately activate the mud prevention, monitoring and response plans in New Zealand, including transferring all the fish to the Benna Spring and going out until the notice.In addition, more thorough inspections are arranged in all other state fish incubation fields and cooperative trustees in Bennun and Pennsylvania. These incubation fields are connected to the muddy waters of New Zealand or nearby waters.In the process, the mud in New Zealand was detected on the pleasant Gap SFH, which is adjacent to the Logan Branch of Spring Creek, which is a water containing an invasive snail.All other SFH checks are negative.Four collaborative trustees that were discovered by Northampton, LEHIGH and Franklin Counties were found to be found in New Zealand mud.
Although the area of SFH in Benna’s spring and the pleasant gap SFH containing fish has not been detected, New Zealand’s mud is not detected, according to the response plan, the immediately taken action to enhance the biological safety measurement of all SFHS and conduct advanced risk assessment.Actions include installation, maintenance or replacement of bird nets on the fish runway.Incubes an additional frozen machine for disinfection and wading; other electrical barriers are installed around the incubator facilities to prevent the snail from moving towards the incubation field.Large -scale disinfection operations were performed in Benner Spring and Pleasant Gap SFHS, including high -pressure and high -temperature steam cleaning and dry runways, and burn any organic materials in the runway with propillene torch.Establishing a isolated area in the incubation site for monitoring fish, and sampled fish digestive materials on hundreds of fish to detect the existence of any New Zealand mud.
Although continued to follow these strict operations for several months, on the spring and pleasant Gap SFHS, several other tests were performed on New Zealand mud and pleasant GAP SFHS.No snails were found in the digestive system of the class.Despite disinfection, inspection and isolation operations will continue to be performed indefinitely in the influential SFHS as part of the processing process of risk assessment, but the catfish and pleasant Gap SFHS in this spring are considered not to be subject to New Zealand mud in Hatcheries’ in HatcheriesExistence and influence.Throughout the spring and summer of 2022, the staff of the PFBC fishery management department carried out a mud survey of New Zealand on the selection of Benner Spring and Pleasant Gap SFHS before the discovery of Hatcheries in May 2022. No snail was found.In October 2022, thousands of fish were removed in the isolation area of the affected incubation field, and it was approved for autumn and winter catfish inventory operations for PFBC.
PFBC continues to cooperate with the operator of the cooperative Toruner, and these operators are found to include New Zealand mud.Thorough inspection, the process of disinfection and risk assessment will continue indefinitely to determine the appropriate use of fish for inventory operations.
In addition to the biological safety measures that have been formulated now, PFBC staff have taken measures for many years to prevent New Zealand mud dissemination, including frequent disinfection of incubation fields and inventory equipment, and installing electrical barriers. Water enters and exits water.The incubation ground to prevent snails from entering the facility.PFBC has been consulted with a water writer to investigate the water source of the affected SFHS and determine whether it can use alternative water sources to further prevent the spread of mud in New Zealand to the facilities.
PFBC also encourages fishingmen and boatmen to inspect and disinfect their equipment between each trip, especially when shifting from one kind of water to another.You can find a prompt to find disinfection equipment on the PFBC website (Fishandboat.com).
Among the 30 waters of Pennsylvania, New Zealand’s mud has been recorded in several popular cold water catfish fisheries in central and east in central and eastern Pennsylvania.These snails are roughly equivalent to the size of the matching head, or even smaller. They are attached to the water -related device, fishing gear and ships, and may reach the potential of hundreds of or even thousands of snails per square meter of streaming beds.New Zealand mud is harmless to humans, but it may compete with local freshwater vertebrate (such as other snails and aquatic insects) and have a negative impact on it.
