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.

Kat Marie Alvarez: Where Innovation Meets Regulation

mm

Published

on

Regulation is often thought of as a limitation, yet in healthcare, it also serves as a foundation for building models that endure. For Kat Marie Alvarez, Founder and CEO of KATALYST & CO, the framework of rules established by agencies like CMS (Centers for Medicare and Medicaid) and the OIG ( office of the Inspector General) create opportunities to design systems that are compliant, ethical, and transformative. Her approach demonstrates that regulation can be a platform for innovation when it is interpreted with both technical rigor and vision.

Kat’s 25-year career reflects this philosophy. A former nurse who advanced into executive leadership and strategy, she has led $2.7B+ P&L operations, advised on over $5B in healthcare transactions, and guided value based organizations including Innovacare, Cano Health, WellMed, Centene, and Humana through periods of exponential scaling. Her perspective combines clinical, financial, and regulatory experience, giving her a unique ability to design structures that support integrity and accountability while driving measurable outcomes.

Turning Statutes into Strategy

For Kat, regulation serves as a framework for building smarter and more ethical models. She interprets CMS guidance and OIG rules as levers for innovation, using them to advance integrity and accountability. With the CMS V28 risk adjustment model, Alvarez refined coding practices, strengthened clinical documentation, and structured risk frameworks that reward accuracy and elevate standards of care. In addressing RADV audits, she crafted strategies that protect stakeholders while keeping patient outcomes at the forefront. She aligns compliance, cost, and care in equal measure. Her current work as a contributor to the CMS IDea Challenge, an initiative focused on strengthening the foundation of trust in our system, further echoes her commitment to advancing regulations in ways that unlock innovation while safeguarding the integrity of care.

Her interpretive approach brings discipline and vision to every challenge. She engages stakeholders to redesign workflows that meet regulatory requirements and enhance the patient experience. Each policy becomes a mechanism to strengthen accountability and operational precision, shaping a system that is both compliant and humane.

Innovation Built Within Boundaries

At KATALYST & CO, this interpretive approach is carried into every project. Kat has integrated predictive analytics and AI-driven tools into care models, with safeguards that ensure interventions remain clinician-led and ethically sound. For example, AI flags in chronic disease management are connected to human-led actions that improve patient care. The result is a model that benefits from technology while preserving accountability and clinical integrity.

Staffing and infrastructure provide another example of her philosophy in action. By leveraging offshore BPO operations in Latin America, Asia, and Eastern Europe, KATALYST & CO extends capacity for health plans and providers. These expansions are carefully designed to meet data security, licensure, and jurisdictional requirements, ensuring that global reach is paired with local compliance. It is a system that balances scale with responsibility.

The Art of Influence Through Alignment

Kat often describes her role as translating complexity into clarity. Whether she is working with payers, providers, or investors, she builds consensus by grounding ambitious strategies in the language of statute. Value-based care models, utilization management programs, and clinical frameworks are designed to prove compliant ROI for stakeholders while maintaining patient focus.

Her approach begins with people. In integrations, partnerships, and platform builds, she respects legacy strengths, listens to frontline voices, and creates systems that are not only efficient but also trusted. This ensures that compliance does not feel like restriction, but like a structure that supports innovation and adoption.

Redefining the Future of Compliance and Care

KATALYST & CO is scaling with $10M in initial funding, expanded international operations, and a growing advisory portfolio. Under Kat’s leadership, the firm is showing how regulation can be a foundation for both innovation and durability. She demonstrates that lasting progress in healthcare is achieved by leaders who know how to design systems that are bold, ethical, and deeply human.

By approaching regulation as a guide rather than a limitation, Kat Alvarez is building models that prove compliance and innovation can move forward together. Her formula ensures that the future of healthcare is shaped not only by ambition, but also by trust and responsibility.
