What are the more common sharks off Nova Scotia? Just curious to know. I know farther out to sea there are porbeagle, mako, blue- I saw a documentary on that. I also saw something about greenland sharks taking seals near sable island. I think whites have been spotted in the Bay of Fundy..?
These traps sound promising in helping to harvest them beyond rec scuba depths.
Love ceviche, and I would really like to try lionfish sashimi- yum.

My understanding is that not only are they voracious and wiping out small and juvenile fish but also contribute to coral destruction by dramatically reducing important herbaceous fish which corals rely on to control algae. Spearing and deep water trapping seems to be important in mitigating...
If your last immersion was in salt water it's also possible you didn't rinse it well enough. In a pinch I've left the zipper open for the first dive and the suit becomes more flexible again.
Yes I realize that, it was more a response to an earlier poster who said they had done it in their Rescue course- agency not specified. Seems a skill that should be taught to the average rec diver at some point in those initial certs. I wouldn't want to be diving around kelp without feeling...
We went through D&D on the surface for my OW but I don't recall practicing underwater. It's possible it was demonstrated but I don't recall- this was with NAUI 18yrs ago. An underwater D&D also wasn't practiced in my PADI Rescue. I guess the prevailing wisdom in early training courses is that if...
Makes sense but in my case it wasn't dive op policy as I have gone with them many times and I was into several dives this trip. I think the DM just had his own procedure. Which is fine- but in the very least tell me you are going to shut my tank off.
Same thing happened to me last week. A DM turned my air off, his procedure was for him to turn all tanks on himself in the boat after gearing up. I gave him an irritated look and told him to at least let me know next time. Frankly I just like being the last person to touch my tank valve.
I was taught to dunk my BC or at least the straps. I got out of the habit until I saw someone panic when their tank slipped so I've made a point of doing it again- especially if renting gear. Helps with the weight belt too.
I've read about using deepwater traps as well as robotic devices:
Deep-Diving Robots Zap, Kill Invasive Lionfish
I don't see how these could possibly eliminate them however.
It's possible they did take a surface drift into account. But if it was an underwater incident and the boat had left to seek them down current they would undoubtedly be criticized for abandoning them in a more urgent situation. It sounds like they really needed more than one boat. I wonder how...
I did one in Cuba where the bull sharks congregate naturally in a narrow channel at certain times of year. However the guide's do coax them by hand with small pieces of fish to come closer which I'd rather they not do. The thing is the dive itself is pretty nice even without sharks- a shore dive...
The Pacific Northwest is also a diving hotspot- notably the Salish sea in BC and Puget Sound in WA. In Canada I'm not aware of any significant restrictions but there are sites where a permit or registration is required.
Good grief- running hot water! Ah well perhaps Cuba is not for you then :wink: Actually the better diving tends to be away from the popular tourist spots where the decent hotels are. I'm thinking Holguin might work for you- it's less busy than Varadero and there are a couple of good hotels...
Yes certainly plenty of interest there beyond diving :) But don't forget Cuba is not really a novelty for Canadians, it's easily accessible from most cities- especially from Toronto and Montreal. I typically go 2-3 times a year.
There are inexpensive 3-5 day packages to Varadero from Toronto- also to Holguin and the Cayos. The Bay of Pigs is a popular spot to dive and can be done as a day trip from Varadero. Habana is also nearby which is also a big plus in terms of things to do.
