Lift Traps

    In 2019, 2 transects of 3 lift traps were deployed per study creek. Lift traps within transects were placed at 15m, 30m, and 45m. Lift traps captured a square 2 x 2m area, enclosed with a 5mm mesh walls that were dug into the marsh surface and supported by bamboo poles when raised. 

Sampling Collection and Processing

Lift trap collections occurred at night within 48 hours of the monthly spring tide for the months of July and August 2019. At slack high tide teams quietly approached the nets and deployed them capturing any mummichogs inside the area during high tide. Once the tide lowered, the fish were recovered from the traps. In the lab the mummichogs were measured to the nearest millimeter and weighed. All weights were measured to the nearest 0.001g. For fishes total length (TL) was measured from the tip of the snout to the end of the caudal fin. The fish were dissected and stomach and intestine mass (stmass) was weighed, stomach and intestine content was then extracted and weighted (ctmass). Stomach contents were identified, if possible. Catches from 30m and 45m were combined into one bin for analyses.
