Scientists can track movements and develop a strategy to locate locations of concern. GIS can be used to track invasive species, endangered species, and population changes. One of the advantages of the system is the availability for the information to be shared and updated at any time through the use of web-based data collection.
The distinctive characteristic of these fish is a scaly sheath around the dorsal and anal fins. The dorsal fin is deeply notched between the 10 spines and the 9 to 13 soft rays. The opercle has two spines, and the anal fin three. Their bodies are compressed and silvery, and they tend to be small, growing to 50 cm at most.

Given FishBase's success, there was a demand for a database covering forms of aquatic life other than finfish.
