How to start fish id'ing?

Nike style, "Just do it!".

You can use wet notes and write down the fish name and quantity.

Name/Quantity (S Single 1, F Few 2-10, M Many 11-100, A Abundant 100 +)

REEF BUTT (Reef Butterflyfish) M (Many)

The REEF slates http://www.reef.org with a bolt snap work well and fit in pockets. Using the waterproof paper (free with fish id course) and the slate makes it easier to check off the fish seen and faster to enter the data on line as the form follows the water proof paper. Wet-notes make you scroll up and down the Internet page finding the fish which gets old.

Once you start, you'll find all the fish you know, then start making notes of identifying characteristics of new fish you don't know the names for. Then go look them up. Soon you'll be able to figure out the families "Big lips, Silvery, odd shaped bottom dweller" and go from there.

On the next dive, you'll find the old fish, the new fish you just learned (re-enforcing the memory and learning) and then take notes on some new fish to look up when you get home. Then the cycle continues. Then go to class to answer the tough questions and learn some new families of fish to look for.

Diving with other fish id divers speeds things up as they can tell you the name of the fish underwater saving you the "look up" phase of learning.

Also, you'll start with the big fish, Grunts, Angels, Butterflies, and move to the smaller fish, Blennys and Gobies. Once you figure out that Rough-head Blenny's are abundant and not just the "single one your found" you've reached fish id nirvana and enlightenment.

Soon every dive becomes a treasure hunt for fish. You'll be the one on the boat saying, "Did you see that hovering goby?" and everyone else will be wondering what your talking about? All they saw were Angelfish, a Barracuda, and a Green Moray.

CACA FRITA!!!!

I thought Mike and Dave left me with full deco bottles. My o2 only had 1200 psi. Emailed Jody an update. Jody had 3000 psi fill from Alex so we equalized the bottles to 2K psi each. Nice!

The seas were 2ft, but choppy as all hell, we were taking water over the bow. It was a very rough ride. Once we got there, seas were 1 ft, very calm.

Current and wind was moving the boat at 3.2 knots. We figured 2 knot surface current with 300 foot drop.

I wasn't sure about Bryan finding our lift bag so I volunteered to take the Riffe float. We got down and 15 5ft jacks circled us and scared the shite out of us! We hit 196ft and couldn't see the wreck. We hit the trigger and Jody took off, I stayed in place, the Gavin pulling me forward and the flag line pulling me back.

We reviewed "dead float" procedure with Bryan before the dive.

So do we, sand dive, let go of the float and scooter to the wreck, or abort? We didn't review these options on the surface as part of the plan.

I singled, "let go" and got a positive response, so I let go of the reel to head for the wreck. Jody looked puzzled and thumbed.

We aborted and surfaced 35 minutes later.

At 70ft switch, my reg was at 0 psi and I hardly purged it before putting it in my mouth, I got a blast of salt water on the first breath. I coughed several times and get it cleared. Jody was right their monitoring the situation.

Our lift bag was parallel to the float about 100ft away. We made it very easy for Bryan to find us!

In the future....

1. We dive the deeper wrecks when conditions are good. We bring a stage of 32% and dive something easy when conditions suck.

2. Next time we'll anchor up on the wreck and scooter down the line to make sure we hit it. We are not smart enough to bomb, and we can't "read" the bottom to the wreck. Past 150ft its just too dark and our eyes take several minutes to adjust to the lack of light which hinders us on descent.

3. I think G3 might be wrong about dragging a float with current past 150ft. Maybe 200ft without current, but with current and rough seas, its not happening.

Strike 2 on the Star Trek.

Armed and dangerous - Flipper the firing dolphin let loose by Katrina

Mark Townsend in Houston
Sunday September 25, 2005
The Observer

It may be the oddest tale to emerge from the aftermath of Hurricane Katrina. Armed dolphins, trained by the US military to shoot terrorists and pinpoint spies underwater, may be missing in the Gulf of Mexico.

Experts who have studied the US navy's cetacean training exercises claim the 36 mammals could be carrying 'toxic dart' guns. Divers and surfers risk attack, they claim, from a species considered to be among the planet's smartest. The US navy admits it has been training dolphins for military purposes, but has refused to confirm that any are missing.

Dolphins have been trained in attack-and-kill missions since the Cold War. The US Atlantic bottlenose dolphins have apparently been taught to shoot terrorists attacking military vessels. Their coastal compound was breached during the storm, sweeping them out to sea. But those who have studied the controversial use of dolphins in the US defence programme claim it is vital they are caught quickly.

Leo Sheridan, 72, a respected accident investigator who has worked for government and industry, said he had received intelligence from sources close to the US government's marine fisheries service confirming dolphins had escaped.

'My concern is that they have learnt to shoot at divers in wetsuits who have simulated terrorists in exercises. If divers or windsurfers are mistaken for a spy or suicide bomber and if equipped with special harnesses carrying toxic darts, they could fire,' he said. 'The darts are designed to put the target to sleep so they can be interrogated later, but what happens if the victim is not found for hours?'

Usually dolphins were controlled via signals transmitted through a neck harness. 'The question is, were these dolphins made secure before Katrina struck?' said Sheridan.

The mystery surfaced when a separate group of dolphins was washed from a commercial oceanarium on the Mississippi coast during Katrina. Eight were found with the navy's help, but the dolphins were not returned until US navy scientists had examined them.

Sheridan is convinced the scientists were keen to ensure the dolphins were not the navy's, understood to be kept in training ponds in a sound in Louisiana, close to Lake Pontchartrain, whose waters devastated New Orleans.

The navy launched the classified Cetacean Intelligence Mission in San Diego in 1989, where dolphins, fitted with harnesses and small electrodes planted under their skin, were taught to patrol and protect Trident submarines in harbour and stationary warships at sea.

Criticism from animal rights groups ensured the use of dolphins became more secretive. But the project gained impetus after the Yemen terror attack on the USS Cole in 2000. Dolphins have also been used to detect mines near an Iraqi port.

After not booking a Tenneco trip fast enough with RJ, Ralph F. and I decided to finally go for the "Grand Traverse" at Lauderdale by the sea. We dropped all our gear at Palm Street in the portal. Lots of shade and sand free wall space to gear up. I parked the Escape at El Prado and walked back. We gear up with double AL 80s and headed out.

I"ll post more details later as I took notes, but the best areas to dive are Hibiscus to Palm and Datura to El Prado.

Heading North from Datura on the 2nd reef line, I always ended up turning at the "Big Dipper" a huge Star Coral with about a 10ft diameter base and several more colonies right next to it. That actually is the beginning of the BEST part. I found a Brain Coral of about equal size and very high coral density. It was incredible and I can't believe after 100 dives at LBTS I was missing the best part!

Once the portals are done I will write up some new shore dive plans for making the shorter transverse from Datura to El Prado out in front of the pier.

We saw about 10 lobster, caught several and only one was legal.

We didn't notice any concentrations of red algea!

Good Stuff!

Dive time 180 minutes (3 hours) beating my previous record of 2 hours and 45 minutes. We averaged about 20 minutes per block for 6 blocks plus the 20 minute swim out and back in.

Distance: Approx 1 mile.

Gas: Ralph and I both had 500 psi left of 32% in dub 80s at the end of the dive.

Photos, Panoramics, and more to come.

I left this one of the Rio Miami raw so you could see how the pieces really come together. With the "stamp" tool I can fill in the water in the background.

Now I can't wait to try this on the reef or at datura, if the vis improves and seas calm!

After 3 weeks of being dry, a new sad record for me, I finally got back in the water. I've been busy with photos from the Saint Louis trip, also posted to flickr. I have become addicted to photomerge in Photoshop Elements so I talked my team in to following me around a couple of the big wrecks off Miami and trying it out. This one had the best results
