“…A large number of studies have shown that the introduction of fishing moratoriums and ARs can gather organisms in the reef area, which can conserve and enhance fishery resources (Fabi & Sala, 2002 ; Wang et al, 2018 ). The earliest documented AR occurred in the 1830s, when logs from huts were used to the coast of South Carolina, United States, to improve fishing yield (Weisburd, 1986 ). AR is a widely used tool for fisheries restoration and has been researched extensively.…”

The biological and ecological integrity of marine ecosystems in the Pearl River Estuary (PRE) has been compromised due to overfishing and water pollution. Fishing moratorium and artificial reef construction have been implemented in Wanshan and Miaowan for resource protection and restoration. Therefore, food web structure and trophic pathways of Wanshan, Miaowan, and Wailingding in different temporal and spatial situation will be determined using the Ecopath model, as well as the keystone species affecting these ecosystems, which can provide a basis for fishery management. The results showed that the energy transfer efficiency of IV and V trophic levels (TL) was higher than that of II and III‐TL before and after fishing moratorium, and the energy transfer efficiency of artificial reefs II and III‐TL was only slightly higher than that of nonartificial reefs in Wanshan. In addition, the mean values of ecosystem property indicators (consumption, respiration flow, total system throughput, and total biomass) after the fishing moratorium were significantly higher than those before the fishing moratorium. The average value of the ecosystem attribute indicators (consumption, respiration flow, total system throughput, and total biomass) of artificial reefs is lower than those of nonartificial reef areas, which may be related to the differences in community composition between artificial reefs and non‐artificial reefs. Finally, Nemipterus japonicus and Gastrophysus spadiceus are keystone species that distinguish the Wanshan and Miaowan artificial reefs from other areas. Overall, the fishing moratorium has a positive effect on the short‐term restoration of fishery resources, mainly restoring short‐life cycle organisms. However, the construction of artificial reefs will be more conducive to the persistence of ecosystem restoration. In addition, reasonable proliferation, release and fishing of N. japonicus and G. spadiceus will be beneficial to the sustainable utilization of fishery resources.

“…The artificial reef (AR) is a submerged structure deliberately placed on the seabed to mimic the functions of a natural reef, such as protecting, regenerating, concentrating, and enhancing marine organism stock, and serves as a part of the natural ecosystem (FAO, 2015). The earliest recorded AR was from the 1830s, when logs from huts were used off the coast of South Carolina, United States, to improve fishing (Weisburd, 1986). The first scientifically planned reefs were deployed in 1974 off the Adriatic coast of central Italy (Fabi and Fiorentini, 1994).…”

Evaluation of Site Suitability for Artificial Reefs Deployment in Southeast Coast of India Using Geographical Information System as a Management Tool

A planned artificial reef (AR) deployment program as part of a fisheries enhancement might be a useful tool for managers to supplement traditional ways to utilize available space and augment local productivity. Several AR deployment initiatives have been carried out globally, but they are rarely subjected to a rigorous site selection process. We created a site selection procedure in this study that includes systematic stages including exclusion mapping, underwater visual transect, benthic composition, seawater quality, and comparative visual mapping. This research focused on restoring the fishing grounds for artisanal fishermen by deploying AR along the southeast coast of India. The results of each stage in the procedure enabled us to choose suitable locations at a target depth with low wave action, no slope, and a good substrate capable of supporting an AR. Analysis of variance (ANOVA-one way) showed significant (p < 0.05) spatial variation for depth, slope, seawater current, salinity, chlorophyll-a, benthic density, and diversity. The geographical information system (GIS) based model output showed space allocation for AR deployment. The GIS methodology for site selection was developed to be easily adaptable to the demands of diverse artificial reef programs. The integrated strategy has proven to be a successful regulatory intervention for AR deployment practices in order to facilitate coastal restoration and management.

“…did the same for archipelagos of coral reefs; the theory may also prove to be useful in explaining the success, or lack thereof, of artificial reefs being constructed in the ocean(Weisburd 1986). Different nuances of the theory may be highlighted with each case, but the basics probably apply in most of them.…”

tion ensures that we will reap such benefits in the future. Examples abound (Oldfield 1984). The value of plants for medicinal purposes is one example of the economic benefit of preserving species. Hie International Union for the Conservation of Nature and Natural Resources recently estimated the worldwide retail value of tropical plants for medicinal uses at $20 billion (WWF 1986). The third argument, and perhaps the most critical one, is that ecosystems and the organisms they comprise provide us with services upon which we humans depend for survival, for example, production of oxygen, nitrogen fixation, and breakdown of organic wastes and chemical pollutants, among many others (Pimentel et al. 1980). Aside from survival value, the services provided by ecosystems are of great economic benefit to society. Hie benefit, however, tends to be underestimated because the interconnectedness of components of the biosphere is not always recognized. Consider, for example, the ability of soil micro-organisms to fix nitrogen from the atmosphere. Assigning a dollar value to the nitrogen in the soil inadequately accounts for the benefits provided by nitrogen because other, related services, such as better soil erosion control and support of larger or more diverse plant and animal populations, are also provided Trophic Level: aganisms that obtain food (Westman 1977). from plants by the same number of steps The problem belong to the same trophic level.
