3 Myths About Deep Sea Catch-And-Release Fishing

When divers resurface too quickly from deep water, the intense change in pressure can make gasses dissolved in their blood bubble up. This problem can lead to nausea, fatigue, joint pain, and paralysis. In the worst cases, it can be fatal. 

This is known as barotrauma, and it doesn’t only affect us. Dolphins, fish, and sea turtles can suffer severe injuries from sudden pressure changes. 

When anglers pull fish from water 30 feet deep and more, their catch is susceptible to barotrauma. Coming rapidly to the surface can make the swim bladder in fish inflate or rupture. This can lead to the death of the fish. 

If you’re deep-sea fishing and want to release a fish instead of eating it, you should know some myths about barotrauma: 

#1: If The Fish Isn’t Bloated, There Is No Barotrauma

Bloating is indeed the most common sign in a fish you’ve caught. However, some fish – including sharks and cobia – lack swim bladders. They might not show bulging eyes or float on the surface after you release them, but they still could suffer from gasses in their tissues, just like people. 

#2: A Fish That Swims Away Is Fine

Some anglers believe if a deepwater fish swims away with no apparent injuries that it doesn’t have barotrauma. Not necessarily. 

Research indicates that barotrauma can have effects later that we don’t always see when we release the fish. A fish might swim away but still be injured. Then, it could get eaten by a predator as it swims back to the reef. 

A barotrauma study on red snapper found that at least 15% of fish taken from deepwater died almost immediately. About 13% of fish were able to swim away but died within three days. So, nearly one out of three fish in the study did not survive catch and release. 

Reef fish, particularly the oldest and biggest females that produce the most eggs per year, are too valuable to the ecosystem to be lost at that rate. It’s essential for anglers who catch and release to use release methods that provide fisher with a better chance of living another day. Even a small improvement in survival rates for these fish can mean millions more fish are saved every year. 

#3: Venting Is The Only Way To Treat Barotrauma

Venting means puncturing the side of a fish’s body with a metal tool. When it is done right, venting can release the built-up gasses so they can escape from the bladder. This improves its ability to go back down deep and hopefully survive. 

But venting comes with problems. First, it can be hard to vent the fish correctly. You need to have a decent knowledge of fish anatomy. If you poke it a few inches the wrong way, you could damage the fish’s internal organs. Also, you should not vent a fish when the stomach is sticking from the mouth or when the intestines come out of the anus. This can kill the fish. 

Even if you vent the fish correctly, it still can suffer from the procedure, including a damaged swim bladder or infections. 

Venting does improve the chance the fish will survive, but there are other options. 

Try A Descending Device

A descending device returns the fish to deep water, where it can usually recover from barotrauma. You can use a descending device on any fish species, and you don’t even need to know fish anatomy!  The more anglers that use descending devices, the more likely deepsea fish will thrive. And that is good for our planet.

Wanda Knight on Blending Culture, Style, and Leadership Through Travel

The best lessons in leadership do not always come from a classroom or a boardroom. Sometimes they come from a crowded market in a foreign city, a train ride through unfamiliar landscapes, or a quiet conversation with someone whose life looks very different from your own.

Wanda Knight has built her career in enterprise sales and leadership for more than three decades, working with some of the world’s largest companies and guiding teams through constant change. But ask her what shaped her most, and she will point not just to her professional milestones but to the way travel has expanded her perspective. With 38 countries visited and more on the horizon, her worldview has been formed as much by her passport as by her resume.

Travel entered her life early. Her parents valued exploration, and before she began college, she had already lived in Italy. That experience, stepping into a different culture at such a young age, left a lasting impression. It showed her that the world was much bigger than the environment she grew up in and that adaptability was not just useful, it was necessary. Those early lessons of curiosity and openness would later shape the way she led in business.

Sales, at its core, is about connection. Numbers matter, but relationships determine long-term success. Wanda’s time abroad taught her how to connect across differences. Navigating unfamiliar places and adjusting to environments that operated on different expectations gave her the patience and awareness to understand people first, and business second. That approach carried over into leadership, where she built a reputation for giving her teams the space to take ownership while standing firmly behind them when it mattered most.

The link between travel and leadership becomes even clearer in moments of challenge. Unfamiliar settings require flexibility, quick decision-making, and the ability to stay calm under pressure. The same skills are critical in enterprise sales, where strategies shift quickly and no deal is ever guaranteed. Knight learned that success comes from being willing to step into the unknown, whether that means exploring a new country or taking on a leadership role she had not originally planned to pursue.

Her travels have also influenced her eye for style and her creative pursuits. Fashion, for Wanda, is more than clothing; it is a reflection of culture, history, and identity. Experiencing how different communities express themselves, from the craftsmanship of Italian textiles to the energy of street style in cities around the world, has deepened her appreciation for aesthetics as a form of storytelling. Rather than keeping her professional and personal worlds separate, she has learned to blend them, carrying the discipline and strategy of her sales career into her creative interests and vice versa.

None of this has been about starting over. It has been about adding layers, expanding her perspective without erasing the experiences that came before. Wanda’s story is not one of leaving a career behind but of integrating all the parts of who she is: a leader shaped by high-stakes business, a traveler shaped by global culture, and a creative voice learning to merge both worlds.

What stands out most is how she continues to approach both leadership and life with the same curiosity that first took her beyond her comfort zone. Each new country is an opportunity to learn, just as each new role has been a chance to grow. For those looking at her path, the lesson is clear: leadership is not about staying in one lane; it is about collecting experiences that teach you how to see, how to adapt, and how to connect.

As she looks to the future, Wanda Knight’s compass still points outward. She will keep adding stamps to her passport, finding inspiration in new cultures, and carrying those insights back into the rooms where strategy is shaped and decisions are made. Her legacy will not be measured only by deals closed or positions held but by the perspective she brought, and the way she showed that leading with a global view can change the story for everyone around you.
