Capitella teleta Blake et al., 2009 is an opportunistic capitellid originally described from Massachusetts (USA), but also reported from the Mediterranean, NW Atlantic, and North Pacific, including Japan. This putatively wide distribution had not been tested with DNA sequence data; intraspecific variation in morphological characters diagnostic for the species had not been assessed with specimens from non-type localities, and the species status of the Japanese population(s) was uncertain. We examined the morphology and mitochondrial COI (cytochrome c oxidase subunit I) gene sequences of Capitella specimens from two localities (Ainan and Gamo) in Japan. Specimens from Ainan and Gamo differed from C. teleta from Massachusetts in methyl-green staining pattern, shape of the genital spines, and shape of the capillary chaetae; we concluded that these characters vary intraspecifically. Species delimitation analyses of COI sequences suggested that worms from Ainan and Massachusetts represent C. teleta; these populations share a COI haplotype. The specimens from Gamo may represent a distinct species and comprise a sister group to C. teleta s. str.; we refer to the Gamo population as Capitella aff. teleta. The average Kimura 2-parameter (K2P) distance between C. teleta s. str. and C. aff. teleta was 3.7%. The COI data indicate that C. teleta actually occurs in both the NW Atlantic and NW Pacific. Given the short planktonic larval duration of C. teleta, this broad distribution may have resulted from anthropogenic dispersal.

“…In general, negative environmental effects of the discharge of aquaculture waste are more pronounced in enclosed or semienclosed areas with poor or limited water circulation. Other negative environmental effects associated with aquaculture wastes include toxic algal blooms (Kaartvedt et al, 1991), reduced and or anoxic benthic sediments (Holmer and Kristenen, 1992;Hargrave et al, 1993;Wu et al, 1994), decreased benthic faunal biodiversity (Brown et al, 1987;Weston, 1990;Tsutsumi et al, 1991, Ye et al, 1991Hargrave et al, 1993), and accumulation of pathogenic and antibiotic-resistant bacteria (where antibiotics are added to feed) (Husev&g et al, 1991;Samuelson et al, 1992;Kerry et al, 1994).The discharge of nutrients from a 1 ha intensive shrimp pond is estimated to be about 1570 kg nitrogen and 430 kg phosphorus per year (Roberston and Phillips 1996) .

The increase in the production of several marine species has been particularly spectacular.Salmon production increased over ten fold and marine shrimp over four fold from 1985 to 1994. Aquaculture production accounts for about a third of the total production of both of these species (New, 1997). Aquaculture production is projected to continue to increase in the near future to meet the world's growing protein demand (New, 1997).The expansion of aquaculture has caused some environmental degradation. The major problem is the discharge of untreated effluent into receiving water bodies.The discharge of this effluent can lead to hypernutrification (increased dissolved nutrient levels) and eutrophication in the receiving water body.Effluent is generated through the exchange of water or draining ponds for harvest.

“…The surface layer of the sediment turns black, smelling of hydrogen sulfide. Under such conditions, macro-benthic communities are likely to be poor and are comprised mainly of small and short-lived polychaetes (Pearson & Rosenberg 1978, Tsutsumi & Kikuchi 1983, Tsutsumi et al 1991, Diaz & Rosenberg 1995, Rosenberg et al 2001. Therefore, through quantitative surveys of the macro-benthic communities, we are able to evaluate the negative impact of increased organic enrichment of the sediment and the occurrence of hypoxic waters on the benthic ecosystem.…”

Abstract:In the inner part of Ariake Bay, located on the west coast of Kyushu, in western Japan, red tides have occurred with more frequency since the second half of the 1990s. Hypoxic waters have occurred during the summer months since the 2000s, despite the fact that nutrient loading from the land to the bay has not increased over the last five decades. We monitored water conditions at nine stations in the inner part of the bay, conducted benthic environmental surveys, and quantitative samplings of macro-benthic communities at the innermost four stations between 2002 and 2008. Each summer, the water was well-stratified due to the development of a halocline and a thermocline. The DO of the water below the pycnocline fell to hypoxic conditions. At the innermost three stations in the bay, the mud content and organic matter content of the sediment increased significantly, and the carbon stable isotope ratios of the organic matter contained in the sediment ranged between −21.3±0.5 and −20.7±0.5 of δ 13 C. These facts indicated that the organic matter was derived photosynthetically from marine phytoplankton. The increase in the mud content of the sediment indicates a deceleration in the tidal current. This may be a key event that induces a series of environmental changes and disturbances, including the stratification of the water, the more frequent occurrence of red tides, the progress of the organic enrichment of the sediment, and the occurrence of hypoxic water during the summer.
