Jumped on ScubaWork's boat "Divocean" on Aug 6th. Thursdays are nitrox & advanced certs, dedicated harvest days at ScubaWorks in Jupiter. Easy to find my 6 bug limit and grab the ingredients for lionfish ceviche while cleaning the reef.

Conditions today were 81゚ on the bottom with a 2 kt swift current, 50' of visibility and flat calm seas. About a 3rd of the bugs that were brought up were darker red color. That means they moved up from the very deep ledge after the hurricane pronounced " ees-ah-EE-ahs " pushed through over the weekend. We got lucky with almost zero hurricane effects and incredible diving. It's almost the end of summer, jump in a car or rent a small RV and go diving !!

Thanks for the report. Interesting about the bugs coming up to shallower water. Any idea as to why they are doing that?
 
.. Any idea as to why they are doing that?
The lobster scientists tell us that bugs are hyper-sensitive to both Dissolved Oxygen and Salinity in the water(way more than fish). Throw one or both of those parameters out of whack and lobsters will " Walk ". This is why we watch the flood gate openings for Lake Okeechobee. If they open and spill millions of gallons of fresh water into the ocean, it will push the lobsters out of the inland waterways several days after the dump. It literally is a straight line of hundreds of bugs walking to better salinity waters.

The same is true for Dissolved oxygen. In very cold water down deep there can be as much as a 30-40% reduction in dO2. We normally get some upwhellings of cold water this time of year when it will drop from 80 degrees down to 62 degrees in the 120ft deep ledges. The bugs need more O2 so they will walk up to the shallower & warmer waters. The fast currents also helps them make this walk. The hurricane last weekend stirred everything up and that just makes it easier for traveling lobsters.

This is why we love to dive after a fast moving hurricane if the rainfall amounts are minimal over the land. It moves all the lobsters around to new holes and in shallow. The shallow lobsters have a greenish/tan color on their tails. That vegitation is not found much below 120ft and it's just the red algae stuff down there, so the deep lobsters have more of a reddish/tan tail color.
