متن کاملThe effect of artificial reefs on fish assemblage versus natural sites in the Bandar Lengeh-Iran
Artificial reefs are used to compensate the destruction of marine ecosystems. In the present study, the effects of artificial reefs were compared to natural sites. For this purpose, five treatments including four different forms (Reef ball (R), Laneh Mahi (L), used materials (U) and R+L+U) of artificial reefs and one control were established. The reefs were deployed at Bandar Lengeh, the Pers...

متن کاملFish attraction to artificial reefs not always harmful: a simulation study
The debate on whether artificial reefs produce new fish or simply attract existing fish biomass continues due to the difficulty in distinguishing these processes, and there remains considerable doubt as to whether artificial reefs are a harmful form of habitat modification. The harm typically associated with attraction is that fish will be easier to harvest due to the existing biomass aggregati...
متن کاملA designed artificial reef is among the most productive marine fish habitats: new metrics to address ‘production versus attraction’
has local production. The local fish production at this artificial reef was 384 g m−2 year−1, which is within the 105– 887 g m−2 year−1 range reported by Claisse et al., although our study included visitor species not included by Claisse et al. We estimate that the fish production new to the ecosystem may only be 4–5 % of the local production, due to the large abundance of visitor species on th...
