Surface Occurrence

Surface occurrence of ocean sunfish (Mola mola) was recorded during summer (May–September) in the western English Channel off Plymouth over a six-year period between 1995 and 2001. Fifteen individuals of between 0.5–0.7 m estimated total length were sighted during 1651 hours of observation. Nearly all sightings (93%) occurred in June and July in water between 13 and 17°C. Sunfish were mostly associated with frontal and stratified water masses (86%) rather than in cooler, mixed water.

The Status

Recent records for the Ocean Pout, Zoarces americanus (collected 11 February 2011), and the Ocean Sunfish, Mola mola (photograph taken 24 June 2012), in the lower Saint John River system, New Brunswick, add to the list of marine fishes reported from this oceanographically unique estuary system. A total of 62 species of strictly freshwater, anadromous, catadromous, and marine fishes have now been recorded in the Saint John River system, with 49 of these in the Saint John River sensu stricto. The Acadian Redfish, Sebastes faciatus, a species assessed as threatened by the Committee on the Status of Endangered Wildlife in Canada, appears to be among these. While strictly marine fishes may contribute relatively little to the overall biomass of fishes in the Saint John River system, marine species account for 30.6% of the biodiversity of fishes in the river to date. This suggests that marine fishes may be a more significant component of the ichthyofauna of the lower Saint John River system than is generally recognized.

Plate Formation

The constituent layers of the integument of the ocean sunfish are described. An eosinophilic epidermal cell is reported. The method of formation and calcification of the fibrillar plates and tubercles is suggested. Regional variation in the fibrillar-plate formation was observed, and its possible role in the movement of the tail discussed. The tubercle is contrasted with placoid and ganoid scales. The lesions associated with the copepod Philorthagoriscus serratus and the trematode Capsala martinierei are described. P. serratus could, in heavy infections, impare the host. C. martinierei causes only superficial damage. The most important pathological implication of both parasites is that they expose the host to secondary infection.

1. Observations made subsequent to December, 1925, confirm the conclusion that the nitrates in the water of the English Channel, twenty-two miles south-west of Plymouth, are almost entirely utilised by phytoplankton in the summer, and are reformed in early autumn at a greater rate than they are utilised.2. Movements of the water masses are shown to affect the quantity of nutrient salts available for phytoplankton in the waters immediately north of Ushant.3. The effect of land drainage on the quantity of nitrate in the sea is not apparent beyond a few miles to seaward from Plymouth Sound, being masked by the nitrate which is regenerated from dead marine organisms.4. The nitrate in the river and estuarine waters entering Plymouth Sound is nearly all utilised by plants in the rivers and estuaries themselves before reaching the open sea during summer.
