Table 5 Abiotic factors affecting light trap catch

From: Light traps for sampling marine biodiversity

Abiotic factor examined Results References
Current Light traps were not as effective in catching larval fish in a high current area as opposed to a low current area Anderson et al. [48]
Light traps that were allowed to float with current had higher catch rates Thorrold [60]
Turbidity Catch rate decreased with increasing turbidity for larval fish Lindquist and Shaw [86]
Sampling duration, and time of day and night No difference in time of night catches for larval fish Thorrold [60]
There were two peaks in catch rates of invertebrates, one near dusk and one near dawn Tranter et al. [93]
Lunar cycle Highest catch rate at new moon and lowest catch rates at full moon Hernandez Jr and Shaw [64]
Highest catch rates at the third quarter moon (i.e., day 22–24 of the lunar cycle) though not consistent for all species Sponaugle and Cowen [47]
Depth of sample Highest invertebrate catch rates were found closest to the benthos Tranter et al. [93], Tor et al. [92]
For larval fish, catch rate varied with different species having peak catch rates at different depths Fisher and Bellwood [77]
Tidal effects No tidal effects Chícharo et al. [23]
Highest catch rates at low tide Beckley and Naidoo [70]
