Egg Distribution: Lingcod, California, 2001

Description:
This shapefile depicts distribution for eggs of the adult Lingcod (Ophiodon elongatus). The process of creating this shapefile included creating contour lines, in 5-meter intervals, from bathymetry lines. Depth ranges were taken from four different references (see Resource Details Supplemental Information). After the depth range between which this species is most common was determined, they were rounded to the closest 5-meter interval. The deepest and shallowest shapefile lines were connected by a line at the northern end and southern end (determined by their geographical range from north to south). This shapefile was then converted to polygon. The goal of this shapefile was to provide a range in which this species' eggs could occur, given that their habitat is present. Fmales briefly visit spawning areas during winter and spring and only stay long enough to deposit their eggs in crevices and under ledges. Males guard these “nests” for 8 to 10 weeks until the eggs hatch. This coverage displays the geographic range of select Pacific Ocean fish species.
