A new tool to provide wetland services is the floating streambed wetland (FSW), an active hydroponic system consisting of a polymer matrix floating substrate in which living plants are established. Water is circulated from beneath the FSW and across a streambed on the upper FSW surface, coming into contact with biofilms attached to the polymer matrix and associated root structures. Research has shown that FSW technology is efficient in removing nutrients and water contaminants, and recent manufacturer reports claim that FSW technology may also increase total fish biomass in small water...

Age-0 fish sampling is an important tool for predicting recruitment success and year-class strength of cohorts in fish populations. In Puerto Rico, limited research has been conducted on age-0 fish sampling with no studies addressing reservoir systems. In this study, we compared the efficacy of passively-fished light traps and actively-fished push nets for sampling the limnetic age-0 fish community in a tropical reservoir. Diversity of catch between push nets and light traps were similar, although species composition of catches differed between gears (pseudo-F = 32.21, df =1,23, P < 0....
