<p>The TDR sensor was set to sample every 10 seconds and record only dives greater than 2 meters in depth or greater than 30 seconds in duration.

During the study period, sunrise always occurred in the morning period and sunset always occurred in the evening period. Maximum dive depth histograms tallied dives into twelve depth bins: 2-10, 10-20, 20-50, 50-100, 100-150, 150-200, 200-250, 250-300, 300-350, 350-400, 400-500, and greater than 500 m.&nbsp;</p>

Responses of Seals and Sea Lions to Increased Rockfish Density
http://biol.wwu.edu/mbel/?page=research
Responses of Seals and Sea Lions to Increased Rockfish Density
<p><strong>From NSF proposal:</strong><br />
This project is a collaborative study of the responses of harbor seals and other mammalian predators to changes in prey density in Puget Sound. The general study approach will involve multi-year field estimates to observe the responses of predators to rockfish density in protected areas, candidate marine reserves, and unprotected sites.</p>
<p>The collaborating investigators will estimate 1) rockfish density using visual and mark and recapture techniques; 2) predator abundance using aerials surveys and dedicated land observations; and 3) predator food consumption using scat to describe diet, tagging of harbor seals to describe individual foraging sites, and population-based and individual bioenergetics models to describe consumption of rockfish. The investigators will also take into account confounding factors that might explain predator behavior, such as environmental variables and alternative prey, by creating a GIS database from available information from the area. The different field observations and database estimates are explicitly linked through a common hypothesis and coordinated methodologies, and their results will be integrated into a model describing the impact of predation on rockfish populations. The responses of top predators to changes in prey density and their impact on fish populations of interest are unknown. This study will evaluate the effectiveness of MPAs as fish refugia, offer a framework for the management and conservation of marine resources, and provide an exciting opportunity for students to participate in ecological and conservation research.</p>
<p><strong>Hypotheses:</strong><br />
1) Harbor seals and other pinniped species show aggregative responses to changes in prey density. Hence, their abundance will increase with fish density.<br />
2) Harbor seals and other pinniped species show Type 2 or 3 functional responses to changes in prey density. Thus, their consumption rate of a particular prey type follows an asymptotic or sigmoidal curve relative to the prey’s density, respectively.<br />
3) Predation by harbor seals and other pinniped species is sufficiently intense that it impedes recovery of depleted fish populations.</p>
<p><strong>Objectives:</strong><br />
1) Quantify the number of harbor seals and other pinniped species in relation to rockfish density and other environmental (confounding) factors.<br />
2) Estimate the consumption rate of harbor seals and other pinniped species in relation to rockfish density and other prey species.<br />
3) Correlatively estimate the influence of predation by harbor seals and other pinniped species on survivorship and population size of rockfish.</p>
