Ammonia in Aquatic Systems
Critical Issue: Agricultural and Food Systems
Management of ammonia, the primary waste product of fish, is critical to fish health, especially in intensive systems. At low concentrations, ammonia causes stress and damages gills and other tissues. Fish exposed to low levels of ammonia over time are more susceptible to bacterial infections, have poor growth, and do not tolerate routine handling well. At higher concentrations, it will kill fish. Many unexplained production losses have likely been caused by ammonia.

Peces ornamentales de agua dulce comúnmente cultivados en Florida
Critical Issue: Agricultural and Food Systems
Esta publicación revisa brevemente los grupos más comunes de peces ornamentales tropicales de agua dulce cultivados en Florida y sirve como introducción a una serie de publicaciones que cubren estos grupos con más detalle. Para simplificar, los peces se agrupan según la familia o familias relacionadas.

Artificial Reefs in Florida 101 – effects on fish: Part 2 of an Artificial Reef series
Critical Issue: Natural Resources and Environment
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 2 of the Artificial Reefs series, explains how artificial reefs affect fish populations. It will help the interested public understand more about the ecological effects of artificial reefs and provide detailed information to stakeholders including management agencies, local governments, artificial reef manufacturers, and Extension agents, to allow for better-informed decisions about building and managing artificial reefs.

Spawning Potential Ratio: A Key Metric for Managing Florida’s Fisheries
Critical Issue: Natural Resources and Environment
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.

Ecological Influences on Coastal Finfish Recruitment
Critical Issue: Natural Resources and Environment
Florida is experiencing many human and climate-related changes to the aquatic environment that can affect fish. Lost or altered habitat, for instance, can lead to changes in fish populations that may impact survival, growth, or recruitment of those populations. Recruitment influences how many adult fish are later available for spawning and continuing the population. Understanding recruitment and how it is affected by ecological influences is important for considering the potential effects of ongoing climate change, as well as restoration and management of water quality and habitat. This publication provides background information useful to anyone interested in understanding more about factors affecting fish populations and should be especially useful to Extension agents and management agency personnel who would like an overview of these topics before engaging with stakeholders.
