“…The Jangmok 1 hull-fouling macroinvertebrates included 19 species, with a mean density of 16,616 ind./m 2 and a biomass of 3937 gWWt/m 2 . The groups included arthropods (11 species), polychaetes (5), mollusks (2), and other taxa (2). The mean densities were as follows: arthropods 16,257 ind./m 2 (97.8%) with many barnacles, mollusks at 178 ind./m 2 (1.1%), polychaetes at 80 ind./m 2 (0.5%), and other taxa at 101 ind./m 2 (0.6%).…”

“…NIS can cause biodiversity loss and change community structure through the local elimination of native species [2][3][4]. NIS can be introduced by ships and negatively impact marine ecosystems by destroying the habitats of native species, changing species compositions and reducing marine resources [5,6]. Ports are the main focus of NIS, and artificial structures are becoming spots of introduction [2,7].…”

“…Ports are the main focus of NIS, and artificial structures are becoming spots of introduction [2,7]. Marine biofouling of ships docked in ports not only directly damages hulls via corrosion and deformation; it also greatly compromises sailing power, increasing fuel consumption, reducing speed, and lowering propeller efficiency by 15-20% [5,8].…”

Global ecological concern regarding the transfer of fouling organisms to ship hulls is increasing. This study investigated the species composition, dominant species, distribution patterns, community structure, and life-cycle differences of hull-fouling macroinvertebrates on five research vessels (R/Vs: Isabu, Onnuri, Eardo, Jangmok 1, and Jangmok 2) operated by the Korea Institute of Ocean Science and Technology (KIOST). Hull-fouling macroinvertebrates were collected three to five times on quadrats from the upper and middle sectors of the hull sides, bottom, and niche areas (the propellers, shafts, and thrusters). A total of 47 macroinvertebrate species were identified, represented by 8519 individuals (ind.)/m2 and a biomass of 1967 gWWt/m2 on the five vessels. The number of species, density, and biomass were greater on the coastal vessels Eardo, Jangmok 1, and Jangmok 2 than on the ocean-going vessels the Isabu and Onnuri. Among the coastal vessels, barnacles were the most abundant and had the greatest density, while mollusks had the highest biomass. Differences between hull sectors showed that the highest species abundance and density appeared on all hulls in ports and bays where the Jangmok 1 operated, while the highest species abundance, density, and biomass were identified in the niche areas of the Eardo, which operated farther from the coast. The hull-fouling macroinvertebrates that exceeded 1% of all organisms were the barnacles Amphibalanus amphitrite, Balanus trigonus, and Amphibalanus improvisus; the polychaete Hydroides ezoensis; the bivalves Magallana gigas and Mytilus galloprovincialis; and the amphipod Jassa slatteryi. The dominant species were cosmopolitan and globally distributed, and many of them were cryptogenic. Six native species were identified: M. gigas, H. ezoensis, the amphipod Melita koreana, the isopod Cirolana koreana, and the barnacles B. trigonus and F. kondakovi. Eight non-indigenous species (NIS) were detected: the barnacles A. amphitrite and A. improvisus, the bivalve M. galloprovincialis, the polychaete Perinereis nuntia, the amphipods J. slatteryi and Caprella californica, and the bryozoans Bugulina californica and Bugula neritina. Of the fouling macroinvertebrates found on the vessel hulls, 13% were native, and 17% were NIS. More diverse communities developed on the hulls of vessels that operated locally rather than globally or in deep oceans. The species diversity index correlated positively with the total number of anchoring days and coastal operation days and negatively with the total number of operation days and ocean operation days. The macroinvertebrates differed by the area of operation, the port of anchorage, the number of days in operation and at anchor, and the hull sectors. There is no previous research data on hull-fouling macroinvertebrates in the Republic of Korea, and this study provides a basis for future studies to identify introduced species and their differences based on operation area.

“…Anderson et al [30] conducted a study and found that clean propeller has the favourable cost benefits compared to a roughened propeller. Seo et al [31] developed an algorithm and investigated the impacts of biofouling on a propeller performance in open water. The authors` results showed that biofouling present on the propeller increases the torque with increasing fouling rate and therefore, a loss of efficiency is experienced.…”

“…On the hull, the presence of fouling increases the roughness of the surface, hence increasing frictional resistance (Schultz, 2004;Kempf, 1937). On the propeller, the presence of fouling increases the roughness of the blade surface, thus requiring more power to maintain the same speed (Atlar et al, 2002;Seo et al, 2016;Owen et al, 2018). Fouling represents the primary cause of hull (Candries et al, 2003) and propeller (Khor and Xiao, 2011) performance degradation.…”
