Episode 2 - Shark Tagging with NOAA/NMFS


Stinky Mammal Breath Mako


Good numbers of juvenile makos made their presence felt this year and

sharks captured ranged in size from small neonates of ~70 cm up to

sub/adults of up to 2.5 m, FL. One of these large makos had a noticeable

problem with its oral hygiene as we brought it onboard! Russ Vetter and Paul

Shark Tagging with NOAA/NMFS

In late August, Paul Rogers from Flinders University joined scientists from NOAA/NMFS' Large Pelagics Group to conduct an annual juvenile shark survey in the Southern California Bight, which included tagging a variety of sharks with TOPP tags. Paul was kind enough to write up a wonderful series of articles about this work, each of which is accompanied by stunning photographs. Rather than putting up a single, giant blog, I am going to be putting the pieces up individually over the next few weeks -- so stay tuned and check back often for updates!

 

Tagging Sharks in the Southern California Bight

The NMFS team just completed its annual juvenile shark survey in the Southern California Bight. This area is an important nursery ground for blue, mako, white and thresher sharks, all of which are caught in local fisheries. Blue and mako sharks are the two species most commonly caught during this survey although we do occasionally catch mola mola, pelagic rays and thresher sharks as well. Through the survey we collect a range of biological and fisheries data and also deploy satellite tags in collaboration with the TOPP program.

The Mako and Me

"I have been in the water (no cage) many times with makos, and they generally make very bold and fast approaches to the photographer," notes nature photographer Richard Herrmann. "This one was no different."

Interview with a Mako

"Great Whites are a bunch of punks," he said, spitting chum as he spoke. "Ever since that movie by that Steven Spielberg fellow, they all swim around like their fins don't stink. We all have notochords of cartilage, you know. Not just the big bad Great White." Those fightin' words were uttered by Quint, a macho mako shark who hangs out off Long Island.

The Curiously Human Face of Conservation

Russ Vetter, Leg III SHARK CRUISE. Although humans are supposed to be rational, humans decide who lives and who dies based on the curious calculus of cuddly.

Birds, Boats and Longlines

Russ Vetter, Leg III SHARK CRUISE. The surface waters of the open ocean are referred to as the “pelagic zone”, and it is hard for people who have never been out at sea

Nothing Subtle about Shark Research

Russ Vetter, Leg III SHARK CRUISE. Sharks are tough animals and nothing about the gear that is used to catch and study them can be small or delicate.

A Hectic Day

Russ Vetter, Leg III SHARK CRUISE. Tanner Bank has been good to us, producing a variety of sharks and reasonably high catch rates.

Big and Small

Russ Vetter, Leg III SHARK CRUISE. Fishing has been slow inshore so we decided to change our luck.
