This Invasive Lionfish Trip is part of REEF’s ongoing effort to monitor the establishment and consequences of invasive lionfish on native fish populations and reef ecosystems. In addition to learning about lionfish biology and ecology, as well as the background of the invasion, participants will have the opportunity to be trained in safe collection and handling procedures, as well as learn how to dissect and fillet lionfish.

Please note: Although the advertised itinerary for the Belize Aggressor III includes a visit to the Blue Hole (weather permitting), we do not anticipate visiting this destination during this Field Survey Trip.

Transfers: The Belize Aggressor III embarks/disembarks at the Radisson Fort George Hotel dock. Guests arriving in Belize on June 8 will be greeted at the airport by a uniformed Aggressor crew member, who will have a "Belize Aggressor" sign when guests exit the airport. There are two complimentary transfers provided by the Belize Aggressor III from the airport to Belize City at approximately 12pm and 4:30pm, which may vary depending on flight times. Due to several flights arriving around the same time, the van will wait for all guests to arrive before departing the airport. Guests may have to wait up to one hour for the shuttle, however there is an airport lounge with free Wi-Fi. If you prefer not to wait, you may take a taxi (approximately $25) to the Radisson Fort George Hotel and wait there until boarding time, beginning at 3pm. Those who arrive to in Belize prior to June 8 should make their way to the Radisson Fort George Hotel arriving by 3pm on June 8. All guests must be onboard by 6pm. 

At the end of the week, there will be two complimentary shuttles to the airport at approximately 8am and 12pm. Guests departing earlier or later may take a taxi from the Radisson Fort George Hotel.
