Understanding the economic importance of fisheries and coastal resources is vitally important for making good management decisions that affect human communities, local businesses, and environmental and ecological sustainability. This publication is the second part in a three-part series summarizing different economic metrics used in a fisheries context. The first in the series provides an overview. This second publication focuses on regional economic methods used to quantify market activity. It provides a discussion of the most relevant terms and analyses as well as a brief discussion of how one might proceed with a regional economic analysis that would provide these types of measures for Florida’s fisheries as well as aquaculture and coastal resources. It is intended to assist management agencies and Extension agents, as well as the interested public, who seek to understand the metrics associated with quantifying market activity.

Understanding the economic importance of fisheries and coastal resources is vitally important for making good management decisions that affect human communities, local businesses, and environment and ecological sustainability. However, economic “importance” is not a very specific term, and can mean completely different things to different people. We reviewed different fields of natural resource economics to and describe the different economic terms most often used. This information can help management agencies and cooperative Extension agents use the correct terminology and teach the correct terminology in their outreach.

Stock enhancement or “stocking” is one of the oldest, most common, and most popular ways of improving recreational fisheries. Stocking is usually supposed to increase the number of fish available for anglers to catch. Unfortunately, stocking doesn’t always do this. The reasons why it may not always work as planned relate to some important concepts of fish ecology. This publication describes those ecological concepts and then also describes the three primary “outcomes” of stocking that anglers might observe. In the end, stocking can be very effective, but only if the stocked fish survive reasonably well and don’t decrease the population of wild fish.

Recreational fishing, crucially important to Florida’s economy and ecosystems, can be affected by management decisions. Decisions that change the allowable harvest or the type of access to certain fishing areas are often expected to have strong effects on fishing effort, but the outcome of these actions is not always obvious. To provide greater insight into what may happen to fishing effort after management decisions, we describe case studies from the North American fisheries literature, some Florida-specific. These illustrate that the same or similar management actions (e.g., a more restrictive harvest policy) can have opposite effects on total fishing effort depending on the specifics of the case. We use this information as well as additional fisheries theory to explore a specific case study—what might happen if special harvest or access regulations were applied to a popular but ecologically and environmentally sensitive habitat—Florida's St. Martins Marsh Aquatic Preserve.

From red drum to red snapper, many of Florida’s fisheries are managed with specific consideration given to a quantity called the Spawning Potential Ratio (SPR). This conspicuous acronym is an important metric to fisheries biologists and managers. It helps determine harvest size limits for fisheries and drives regulations for both commercial and recreational fisheries. However, SPR is not especially intuitive to the general public or even agency personnel and Extension agents. This publication is intended to describe what SPR is and explain how and why it is used in managing fish stocks. We think it will help people better understand fisheries management decisions, the documents describing them, and the science behind them.

Increasingly, coastal managers are placing artificial reefs in marine waters. These long-lasting habitat alterations have measurable effects on fish, fishers, divers, fisheries, and marine social ecological systems. Understanding how artificial reefs function is necessary to make good decisions about future artificial reefs. Scientific research on many aspects of artificial reefs is not always summarized and explained. In response to this need, we designed a 4-part series called Artificial Reefs 101. This publication, part 4 of the Artificial Reefs series, explores a complicated but fascinating aspect of artificial reefs—should we expect them to lead to better fishing in the long run? Many people think artificial reefs should be a “win-win” since both fish and fishers seem to like them. But it is increasingly apparent that they are likely to increase fishing mortality more than they increase fish populations. So they could lead to more restrictive regulations.
