Bottom Line: In July 2007, > 100 striped dolphins, Stenella coeruleoalba, were found dead along the coast of the Spanish Mediterranean.Of 10 dolphins tested, 7 were positive for a virus strain closely related to the dolphin morbillivirus that was isolated during a previous epizootic in 1990.

ABSTRACT
In July 2007, > 100 striped dolphins, Stenella coeruleoalba, were found dead along the coast of the Spanish Mediterranean. Of 10 dolphins tested, 7 were positive for a virus strain closely related to the dolphin morbillivirus that was isolated during a previous epizootic in 1990.

Stranding patterns of Mediterranean striped dolphins, Stenella coeruleoalba, in the Gulf of Valencia and adjacent waters (Valencian Community) (514 km of coastline). A) Records of S. coeruleoalba stranded in July–August each year from 1987 to 2007. Note peaks of stranding in 1990 and 2007. B) Cumulative percentages of dolphins found dead during July–August, 1990 and 2007 epizootics. Day 0 corresponds to June 23.

Figure 1: Stranding patterns of Mediterranean striped dolphins, Stenella coeruleoalba, in the Gulf of Valencia and adjacent waters (Valencian Community) (514 km of coastline). A) Records of S. coeruleoalba stranded in July–August each year from 1987 to 2007. Note peaks of stranding in 1990 and 2007. B) Cumulative percentages of dolphins found dead during July–August, 1990 and 2007 epizootics. Day 0 corresponds to June 23.

Mentions: In the Gulf of Valencia, the number of stranded animals during July through August 2007 was similar to that recorded in 1990 during the same months (Figure 1, panel A). Stranding rate was also similar during each episode, with an initial low rate at the beginning of July, ≈2 weeks with no stranded dolphins reported, and then a sharp increase of stranding in mid-August (Figure 1, panel B). The most apparent difference between each episode was the size of animals collected: the mean size ± SD of dolphins collected in 1990 and 2007 was 180.9 ± 28.6 cm (n = 34) and 159.9 ± 40.9 cm (n = 17), respectively. This difference is statistically significant (Student t test, t = 2.14, 49 df, p = 0.037).
