Breder Traps
IIn July of 2018, 8 stations of Breder traps were deployed per study creek, 4 stations in both the left and the right branch. Each station had 2 traps, one trap was deployed in the low-marsh area, 1m from the TSA/SP boundary with the opening facing the creek in order to capture consumers as they moved onto the high-marsh area with the rising tide. The second trap is placed in the high-marsh area 1m from the TSA/SP boundary. Breder traps were installed by clipping the grass and staking the trap into the ground to prevent any movement. The trap stations were placed with a minimum distance of 25m, ensuring independent samplings. Sampling was conducted over 2 nights, the 27th and 28th of July.
Tide measurements were recorded via painting a staked meter stick with colored glue, and documenting the height of the water level from the point where the glue was washed away. The meter stick was staked on the marsh surface making the measured levels relative to the water level on the marsh, not the creek.
Sampling Collection and Processing
Traps were left out for 6 hours total, they were placed 3 hours before the incoming tide and collectred 3 hours after peak high tide. When traps were collected all captured consumers were collected and frozen for analysis. In the lab, the captured consumers were measured to the nearest millimeter and weighed. All weights were measured to the nearest 0.0001g. For fishes total length (TL) was measured from the tip of the snout to the end of the caudal fin.
