Telemetry error is not regularly considered in aquatic studies; however, when it is considered, it is generally treated as a static value despite high variation that can occur even within a single tracking event. We describe a simple procedure for using received signal strength (RSS) to estimate telemetry error. We recorded the RSSs of ground‐ and air‐based detections of large (11 g; 11 × 59 mm) and small (8 g; 11 × 43 mm) 172‐MHz radio transmitters across a range of distances….Read more

Energy exploration in the Gulf of Mexico (hereafter, Gulf) has resulted in the addition of numerous oil and gas production platforms that create structurally complex habitat in an area otherwise dominated by barren mud/sand bottom. How these artificial structures affect fish populations is largely unknown, and there is ongoing debate regarding their value as surrogate habitats for ecologically and economically important reef fish species. Thus, the purpose of this study was to…Read more

Hatchery programs have been used as a conservation tool to bolster declining populations of Chinook Salmon Oncorhynchus tshawytscha along much of the North American Pacific coast. In many watersheds, hatchery stocks are released concurrently with the wild population, thus raising the potential for density‐dependent effects. Competition for prey resources during the critical period for early marine growth and survival may diminish the foraging capacity and growth potential of wild…Read more
