Welcome to the FishKit User Guide!
FishKit is a set of publicly available software tools used to support decision-making for small-scale and coastal fisheries. FishKit tools are designed to tackle the dual challenges limiting sustainability in small-scale fisheries: data gaps and limited know-how among local leaders to use data to design and implement management actions. FishKit contains analytical tools known as the Stock Health Tracker, Size Limit Builder, Bag Limit Builder, and Temporary Closures. The FishKit Data Repository is a separate web application for managing information used in FishKit. FishKit draws upon existing, published fisheries science concepts, transforming this information into user friendly, interactive dashboards. FishKit is intended to facilitate the visualization, design, and decision-making process for implementing some types of fisheries management measures.

Fishery
A unit determined by an authority or other entity that is engaged in raising and/or harvesting fish. Typically, the unit is defined in terms of some or all of the following: people involved, species or type of fish, area of water or seabed, method of fishing, class of boats and purpose of the activities.

Population
A self-sustaining group of individuals, from a single species, whose dynamics are primarily determined by birth and death processes.

Stock
An exploited fishery unit. A stock may be a single spawning component, a population, a metapopulation, or comprise portions of these units. For management purposes stocks are considered discrete units, and each stock can be exploited independently or catches can be assigned to the stock of origin.
