  1. Transplant or seed organisms onto intertidal artificial structures

    A replicated study in 2019 on an intertidal seawall on an island coastline in the Singapore Strait, Singapore (Heery et al. 2020) found that red macroalgae Hydropuntia edulis transplanted onto the seawall grew at similar rates at all shore levels, but was more likely to be dislodged at lowshore than at mid- and highshore. Over one month, the biomass of transplanted macroalgae increased by 2 g/individual on average. The average growth rate was 3%/day and average biomass yield was 2 kg/m2 of seawall. Growth rates were similar at lowshore (3%/day), midshore (2%/day) and highshore (2%/day), but the probability of dislodgement was higher at lowshore (58%) than midshore (8%) and highshore (17%). Red macroalgae collected from natural reefs were woven into nylon ropes and transplanted into water-retaining plastic troughs (1.0 × 0.1 m) attached to a seawall. Six individuals were transplanted into each of four troughs at each of lowshore, midshore and highshore in January 2019. Growth rates (% change in wet weight/day) and biomass yield (change in wet weight/m2) were measured during low tide after one month.
