sea lion population is not out of control

BC Sea Lion Populations Are Not Out Of Control

By | Sea Lions | No Comments

A video of a fisherman throwing a bear bomb into a pod of sea lions out in the ocean went viral on the web recently. The fisherman laughed about the incident confirming his distaste for the pinnipeds. He’s not the only fisherman who finds the sea lions pests. Others have been complaining about sea lions eating their herring catch right out of their nets often damaging their fishing gear.

There seems to be a notion that the sea lion and seal population is out of control; however, Fisheries and Oceans Canada, as well as other experts from the Vancouver Aquarium, disagree. The population hovers around 105,000 individuals and has been stable since 1999. The sea lion population is one-third of that of the seal population. The experts say the population is in line with the historical population before the Europeans came to North America and began hunting them to near decimation.

So there is no validity to the perception that the population is growing out of control. The question that needs to be answered is who has the priority for eating the fish, humans or pinnipeds (seals, sea lions)?

TOTOABA ENFORCEMENT

Law Enforcement Disrupting Trade That Is Killing The Vaquita

By | Endangered Species | No Comments

We all know that the Vaquita, a small porpoise endemic to the Sea of Cortez, is nearly extinct; however, there are many organizations that are still fighting to keep the Vaquita from going extinct.

The Vaquita population is in trouble because they keep getting killed from illegal fishing practices in the Sea of Cortez by fishers who are trying to catch another endangered species called Totoaba. Asian countries are seeking out these fish for their swim bladders in which they think has healing properties (it has never been medically proven).

The people working to protect the Totoaba and the Vaquita are having a hard time stopping the fishers from catching an illegal, but high priced fish. Some organizations have moved to stop the middle people from arranging the shipments of Totoaba swim bladders to China from Mexico. And it’s working!

A new commentary on Mongabay news by Andrea Crosta, Executive Director and Co-Founder of the international illegal trade watchdog group, Elephant Action League, describes how her organization and partners have infiltrated some operations that conduct illegal operations to provide information to the proper authorities to make arrests.

Check out the rest of the details by listening to the podcast.

zero waste clothing

How To Shop For Used Clothing With Jackie Lang

By | Plastic Pollution | No Comments

A number of episodes ago, I discussed an article that showed an increase in sales at thrift stores in the UK. I admitted to you that I had never bought 2nd hand clothes before and I couldn’t even tell you how the process works.

I received a number of messages after that episode from the audience telling me about their experiences in shopping 2nd hand and how they did it almost exclusively.

Jackie Lang was one of those people who reached out, so I asked her to be on the show to discuss her experience with buying clothes from thrift stores.

Enjoy the episode and let me know whether you shop at thrift stores. Share your experiences in the Facebook Group: http://www.speakupforblue.com/group.

Waste Shark

Waste Shark Will Eat Plastic along The Coast

By | Plastic Pollution | No Comments

Plastic pollution is a big problem in all parts of the world, especially in harbors and coastal areas where rivers empty into the ocean. There are teams of people who are trying to figure out how to clean up the plastic and debris in the Oceans and there are others that are trying to keep the human population from using more single-use plastic.

A Dutch Environmental Company called RanMarine has developed a drone that will float on the surface of the water that will “eat” plastic. The drone is called the WasteShark. The WasteShark is designed after the whale shark as it swallows everything in its path when it opens its mouth. The drone can “eat” up to 60kg off of one charge of 8 hours.

Take a listen to the episode and let me know what you think about the WasteShark in our Speak Up For Blue Facebook Group: http://www.speakupforblue.com/group.

Great White Shark DNA

The Great White Shark Genome Decoded And Health Secrets Unlocked

By | Sharks | No Comments

The Great White Shark is a mysterious animal. Feared by many and respected by all for their status as an apex predator. The shark has been around for hundreds of millions of years, where it has evolved many times to survive. Scientists have been wondering how a primitive shark could survive for so long without being wiped out. The answer may be in their DNA.

A team of researchers has been able to crack the code of the Great White Shark DNA and they discovered 2 things.

Take a listen to the episode to find out what those important things are.

Leave Stingrays Alone

Parents, Teach Your Kids To Leave Stingrays Alone!!!

By | Ocean Tourism | No Comments

There are a couple of videos that I came across on the internet today that really got me on a rant that I recorded for today’s podcast.

The first video is of a child near a shoreline feeding a stingray shrimp. The child pets the animal and even lifts up the front par to of the stingray to slid food towards its mouth on the underside. All of this is going on while the parents hand the child more shrimp to feed the stingray.

The second video is of a boy who wants to become the next Steve Irwin. The video is of the boy walking along an estuary when he comes across a few stingrays. He takes the stingrays OUT OF THE WATER to show the camera and speak to the audience to show the animal’s features. Taking the animal out of the water is taking away its oxygen supply.

The boy ends up finding a stingray that is giving birth. He pulls the animal out of the water, discovers the babies, and proceeds to pull all of the babies out of the mother by their tails.

In both of these situations, there are parents that are helping these kids touch the animals.

It’s time for parents and adults to teach kids to be kind to animals and leave them alone!!!

Squid Ring Teeth Could replace Microplastics

Squid Teeth Could Replace Microplastics

By | Marine Conservation | No Comments

Imagine a world where your products are not made of microplastics, but some alternative compound derived from squid teeth. Crazy, right? Well, the idea may not be so far fetched.

Melik Demirel, director of Penn State’s Center for Research on Advanced Fiber Technologies, has discovered a way to use the proteins from squid ring teeth (the serrated rings along squid tentacles) as a way to create an alternative to microplastics.

The proteins can be grown in a lab via E. coli; therefore, there is no need to harvest already dwindling species of squid to make the products at a larger scale.

The proteins are tough and have regenerative properties that can make clothing more durable and sustainable.

A life without microplastics may be closer than we think. Share your thoughts in the Speak Up For Blue Facebook Group: https://www.speakupforblue.com/group.

Can't Find A Job In Marine Conservation

Ways To Raise Money To Work In Marine Conservation

By | Ocean Conservation Careers | No Comments

A few episodes ago I spoke about how some Non-profit organizations were taking advantage of early career scientists/conservationists by asking them to work for free on what should be paid positions.

This episode I list alternative ways to work in Marine Conservation without going the traditional 9-5 route.

I would love your feedback on this episode and if you would ever consider following an alternative career path in Marine Conservation. Share your thoughts in the Facebook Group: http://www.speakupforblue.com/group.
