    Techne ® qPCR test Caprella mutica 16S ribosomal RNA gene 150 tests For general laboratory and research use only Quantification of Caprella mutica genomes. 1 Advanced kit handbook HB10.03.07 Introduction to Caprella mutica Caprella mutica, commonly known as the Japanese skeleton shrimp, is a relatively large caprellid reaching a maximum length of 50 mm. They are sexually dimorphic, with the males usually being much larger than the females. Caprella mutica are native to the subarctic regions of the Sea of Japan in northwestern Asia. They are omnivorous highly adaptable opportunistic feeders. In turn, they provide a valuable food source for fish, crabs, and other larger predators. They are usually found in dense colonies attached to submerged man-made structures, floating seaweed, and other organisms. C. mutica are native to shallow protected bodies of water in the Sea of Japan. Recently they have become an invasive species in the North Atlantic, North Pacific, and along the coasts of New Zealand. They are believed to have been accidentally introduced to these areas through the global maritime traffic and aquaculture. Their ecological and economic impact as an invasive species is unknown, but they pose a serious threat to native populations of other skeleton shrimp in the affected areas. In a span of approximately 40 years, they have spread into other parts of the world through multiple accidental introductions from the hulls or ballast water of international maritime traffic, aquaculture equipment, and shipments of the Pacific Oyster. Genetic studies of the mitochondrial DNA (mtDNA) of the populations of C. mutica reveal high genetic diversity in the Sea of Japan region, unequivocally identifying it as their native range.

    CARCINUS MAENAS: A DEMOGRAPHIC STUDY OF AN INVASIVE SHORE CRAB IN THE NEW ENGLAND ROCKY INTERTIDAL Madeline Cole Department of Biology, Clark University, Worcester, MA 016101 Abstract: Carcinus maenas (Green Crab) is an invasive crab species on the east and west coasts of the United States dating back to 1817. The introduction of another invasive species in 1988, Hemigrapsus sanguineus (Asian Shore Crab), has created competitive interactions between the crabs. A demographic study was conducted to compare crab populations. A total of 155 crabs were collected, 25 of which were C. maenas and 130 H. sanguineus. There are significantly more male Green Crabs (21) than female Green Crabs (4) (p>.0001). There are also significantly more female Asian Shore Crabs (81) than males (49) (p>.0001). Correlations between width and limb loss also exist such that as the width of the Asian Shore Crab carapace increases, the number of autotomized limbs increases (p>.0001). These results lead to important questions and further studies regarding competition between these invasive species. Keywords: Carcinus maenas, Green Crab, Hemigrapsus sanguineus, Asian Shore Crab Introduction: Carcinus maenas, the Green crab, in an invasive shore crab originating from Europe and Northern Africa. First recorded on the Atlantic coast of the United States in 1817, it has since successfully invaded the east and west coasts. C. maenas is a small shore crab, measuring about 75mm across as an adult. The dorsal side of the carapace ranges from a dark green to brown with yellow patches. The ventral side can be green, yellow, orange, or red. Its most distinguishing feature is the five triangular spines located to the outside of both eyes (Fig.

This amphipod is indigenous to north-east Asia and has invaded several regions, including Europe, North America, New Zealand and now South Africa. C. mutica was detected in scrape samples from the hulls and niche areas of four yachts resident to False Bay Marina, Simon’s Town, on South Africa’s South Coast. A total of 2,157 individuals were recorded, comprising 512 males, 966 females (20% of which were gravid) and 679 juveniles. The yachts upon which this amphipod was found were not alongside each other, suggesting that the species is widely distributed within the marina. The presence of C. mutica in South Africa has been anticipated, as previous work highlighted the climatic suitability of the region and the presence of vectors between South Africa and other invaded areas. The fast reproductive cycle of C. mutica, along with its high reproductive output, have important implications for its invasiveness in South Africa.

It is believed to have first arrived in eastern North America around 1817, most likely in the dry ballast of cargo ships. The species has since established itself from Delaware to Nova Scotia and is the most common crab species in many locations throughout this range. An omnivorous scavenger, this crab is one of New England’s dominant benthic predators, feeding on clams, oysters, crabs and mollusks. It is often blamed for the collapse of Maine’s soft shell clam industry.
