The Future of Aquaculture

UM Rosenstiel School Professor of Marine Ecosystems and Society Daniel Benetti published an essay on the future of aquaculture in the current issue of The Journal of Ocean Technology.

“In the field of aquaculture, technology has evolved at an enormous pace during the last two decades. Advances in technology are allowing all of us involved in the field, from scientists to operators, to address and tackle most, if not all, contentious issues in aquaculture.”

“Modern aquaculture relies on advanced technologies to produce wholesome seafood for human consumption. Indeed, aquaculture has become as important as farming and agriculture, currently contributing over 50% of wholesome seafood for human consumption worldwide. Aquaculture production continues to increase exponentially and is the fastest growing food production sector, having surpassed beef production in 2012-13 (66 million metric tons vs. 63 million metric tons). “

Eric J. Barron

UM Rosenstiel School alumnus Eric Barron recently took the helm as president of Penn State University. Barron received his Master of Science (’76) and Ph.D (’80) in oceanography from the UM Rosenstiel School. In addition, he spent one year as an associate professor at UM before taking up a new post at the National Center for Atmospheric Research in Boulder, Colorado.

Barron has a distinguished resume, as the former President of Florida State University he lead the university’s rise to a U.S. News & World Report ranking as the most efficiently operated university in the nation. His expertise in the areas of climate, environmental change and oceanography, among other earth science topics, have led to extensive service for the federal government and the international community.

Bite Size Wins Prize in Ocean Video Challenge

1397354_10152193972993265_1324283571_o Bite Size: Bull shark predation of tarpon from UM Rosenstiel School Research Assistant Professor Neil Hammerschlag and Gareth Burghes of Lagomorph Films claimed third place honors in the Ocean 180 video Challenge. This video highlights a collaborative research project with Rosenstiel researchers Dr. Jerry Ault and Dr. Jiangang Luo.

Using three-minute videos, ocean scientists explored a piece of their own recently published research, highlighting its significance and purpose.

To determine who was best at engaging and explaining these new discoveries, the Ocean 180 Video Challenge looked to a group of potential future scientists: a team of nearly 31,000 middle school students from around the world. Viewing each of the finalists, students were asked to evaluate the films for their clarity and message. They were also asked to consider which videos made them excited about the scientists’ research. After 5 weeks of classroom viewing, deliberation, discussion and voting, the three winners emerged.

“The competition is both a great opportunity to communicate our science as well as evaluate how our outreach efforts resonate with young audiences,” said Hammerschlag.

Finalists had their videos viewed by thousands of classrooms around the world, exposing diverse and new audiences to their research. Students also provided scientists with feedback on how to improve their video storytelling and technical skills and ways to make science more relatable to the public.

For some middle school students, and budding scientists, sharing science might be the best part of Ocean 180. As one student judge explained, “It’s not very good to keep information that’s valuable to the world cooped up in a little box. You need to open the box and let everybody see it so they’re more aware of the environment and what’s in it.”

Sponsored by the Florida Center for Ocean Sciences Education Excellence (COSEE Florida) and funded through a grant from the National Science Foundation, the Ocean 180 Video Challenge was designed to inspire scientists to communicate the meaning and significance of scientific research with a broader audience.

A Catch of Another Kind

When Miami fisherman Tim O’Neill went fishing off Key Biscayne one morning in search of swordfish he returned with a much rarer specimen than he had in mind. When he finally reeled in the big chunk of ocean bottom he realized he had hooked a giant tooth.

“I couldn’t grab the rock fast enough,” said O’Neill, captain of the F/V Cacique.

What he reeled in that day from 1800 feet below was an exceptional find – a crustal rock from the ocean floor with a large fossilized shark tooth jutting out. He contacted UM Rosenstiel School scientists to help him identify his unusual find.

According to Rosenstiel School scientists the fossilized upper front tooth encased in rock he caught is from the now extinct relative of the great white shark, Carcharodon megalodon, which is known for its “mega teeth” and estimated to be 10-15 million years old.

“The great white shark that exists today is more closely related to the prehistoric Mako shark than the megalodon,” says Rosenstiel research assistant professor Neil Hammerschlag and director of the RJ Dunlap Marine Conservation Program.

Rosenstiel School marine geology professor Gregor Eberli examined the rock first hand to discover that the black-colored megalodon tooth was well preserved in the limestone rock coated with a mixture of iron and manganese.

O’Neill caught his one-of-a kind find about 10 miles off the coast of Miami in an area known as the Miami Terrace. University of Miami scientists conducting an echo-sounding survey first discovered the region in 1958. The area is of interest to scientists for its mix of geological and biological finds.

“At approximately 1800 feet depth, the Miami Terrace is a large, current-swept submarine plateau whose flank down to the floor of the Straits of Florida at 2600 feet is covered with 100 foot ridges, which provides habitat for deep-water corals, sponges, lobsters and fish,” said Eberli.

Tim O’Neill pulled the rock off the edge of the Terrace. He is planning to keep his million-year-old ocean treasure at home as a reminder that great whites once roamed the Straits of Florida.

A Bull of a Challenge

RSMAS Researcher Assistant Professor Neil Hammerschlag is one of 10 finalists in the Ocean180 video challenge. His research video, ”Bite Size: Bull Shark Predation of Tarpon,” delves into a recent study on the movements of bull sharks and tarpon in South Florida waters. Through satellite tracking, the study reveals some unique behaviors by the large predatory fish in order to avoid becoming bull shark prey.

Sponsored by the Florida Center for Ocean Science Education Excellence (COSEE Florida) and funded through a grant from the National Science Foundation, the Ocean 180 Video Challenge was designed to inspire scientists to communicate the meaning and significance of scientific research with a broader audience.

Over 40,000 middle-school student judges from around the world are now reviewing the top 10 video abstracts. The winners will be announced in late February 2014.

TIGER SHARKS: UNCOVERING MYSTERIES OF A FEARED & MAGNIFICIENT SUPER PREDATOR
Neil Hammerschlag, Ph.D.
Director of R.J. Dunlap Marine Conservation Program, and Research Assistant Professor at Rosenstiel School of Marine and Atmospheric Science

Sharks are one of the most feared and mysterious animals on Earth. However, due to destructive fishing practices, many shark populations globally have drastically declined in recent decades. The tiger shark is the largest predatory shark in tropical seas, renowned for its massive size, beautiful body markings, indiscriminate appetite and occasional bites on humans. By tracking and swimming with tiger sharks, ecologist and shark researcher, Dr. Hammerschlag, has discovered previously unknown migration patterns and behaviors of this super predator. Join Dr. Hammerschlag as he shares his new findings, stories and photos of the enigmatic tiger shark.
