Please join us for a free public presentation about the process known as hydraulic fracturing and the risks that this industrial activity can pose to our health, environment, and economy. Information on produced waste waters and their disposal will also be discussed.
WHEN: Tuesday, February 5th, 7:00 - 9:00 pm

Beluga whales have a small, blunt head with a beak and a rounded melon. Belugas have a dorsal ridge instead of a dorsal fin and a sleek, pure white pigmented body. While the adult beluga whale is pure white the calves are tan and the juveniles are blue to grey. Flippers are short, rounded and wide and the flukes are wide and deeply notched. Beluga whales possess a flexible neck and can swivel their heads right around 90 degrees. Belugas spend between 40 and 60 percent of their time below the surface. Dives can last for 15 minutes and belugas can dive to depths of 800 meters. About 70 percent of dives are over 40 meters deep and 80 percent of dives include prolonged trips to the bottom. Belugas are slow swimmers which take advantage of ocean currents to get around. Usually belugas complete two to three breathing sequences between dives. Belugas can produce whistles and pulsations as well as snaps, creaks and growls.
Harbour porpoises are six feet long and weigh about 140 pounds and are the smallest cetaceans found in Canadian waters. The harbour porpoise has tiny flippers and a triangular dorsal fin and a small, rounded head with a short beak and smiling mouth. Harbour porpoises have a black back and a greyish white area extedning from the belly up the the sides in front of the dorsal fin. Harbour porpoises travel at speeds of 14 mph and surface as many as 8 times at one minute intervals.The harbour porpoise dives to depths of 226 meters. Usually harbour porpoises dive for less than five minutes at a time to depths of 30 meters. Great White Sharks and killer whales prey upon harbour porpoises. Harbour porpoises feed upon a variety of fish including herring, pollack, sole, mackerel, sardines and cod. Harbour porpoises also feed upon squid, octopus and small crustaceans.
American Plaice belongs to the flatfish group of fishes whose members are strongly compressed laterally and tend to lie and swim on one side. When the young fish hatch from an egg they have the normal fish form. During development, as they settle to the bottom of the ocean, a profound change occurs in body structure. the head becomes twisted so that the fish now swims and lies on it's side.
Marine sea turtles are a fundamental link in marine ecosystems as they help maintain the health and vitality of sea grass beds and coral reefs. Sea turtles are specially adapted for lfe in a marine environment and they possess flippers and a streamlined body to enhance their mobility in an aquatic domain Usually female sea turtles come ashore onto sandy beaches in large groups called arribadas and then engage in mass nesting. Female sea turtles can lay up to 100 eggs in each nest. Female sea turtles crawl onto the beach and dig U- shaped holes into the sand above the high tide line. There is usually an interval of ten to fifteen days betweeen the laying of each batch, called a clutch of eggs. From hatchling to adult, Loggerhead sea turtles increase their weight more than six thousand times. Hatchling Loggerhead sea turtles weigh onlhy 0.05 pounds or 20 grams.
Spiny dogfish have a gray or brown top and pale grey or white ventral side with irregular white spots on the body. Essentially the spiny dogfish are torpedo-shaped and are streamlined to permit easier swimming mobility. The average length of spiny dogfish is 30 to 40 inches however some individuals attain a size of 50 inches in length and a weight of 20 pounds. The second dorsal fin is smaller than the first and both fins have spines at their origins. The caudal fin is asymmetrical with the upper lobe being larger. Spiny dogfish have pectoral fins with curved rear margins and they possess no anal fin. The smooth edged, short and oblique teeth are the same in both jaws. Spiny dogfish have a lifespan of 30 years.
Atlantic redfish swim in deep waters at the edge of the major fishing banks and in deep channels carved in the ocean floor. Distinguished by a bony protrusion on the lower jaw and by it's large eyes, the redfish can be found as two distinct species in the northwest Atlantic Ocean. Sebastes Mentella is bright red in colour with a long, well developed beak and is found at depths greater than 200 meters. Sebastes Mentella can reach a length of 60 cm for females and 45 cm in length for males. Sebastes Marinus is found at depths of less than 240 meters and is orange in colour with a small, blunt beak. Sebastes Marinus can reach 70 cm in length for females and can reach 55 cm in length for males. Redfish are preyed upon by cod and turbot and in turn prey upon small fish and crustaceans.
Atlantic salmon have an elongate, slightly compressed body and a rounded snout. In breeding males a hook develops on the lower jaw. In the sea the back and top of the head may be green,blue or brown; the sides are silver and the underside is silvery white. On entering freshwater, the adults become darker in colour and lose their silvery appearance.
Bluefin tuna are a very advanced oceanic fish which are warm blooded and capable of regulating their internal body temperature. Bluefin tuna are the largest species from the Scombrid family and weights of 500 pounds are not at all unusual.
Essentially the Winter Skate resembles a pancake with a short tail and it has a very flattened, depressed body and a slender tail. It possesses a disc about 1.3 times as broad as it is long and a snout with an anterior angle of about 130 degrees. The mouth is gently arched with 63 or more rows of teeth in the upper jaw. The Winter Skate can attain a maximum size of 109 cm total length. Usually the Winter Skate is found living over sand or gravel bottoms, usually in depths less than 111 meters. One Winter Skate was captured at a depth of 371 meters in the Gulf of St. Lawrence. Winter Skate eat mostly amphipods and polychaete worms although they also consume fishes, decapods, isopods and bivalves. Fishes, such as the sand lance, are of greater importance in the diet of large individuals.
Sei whales have a long,sleek body that is dark bluish-gray to black in colour and pale underneath. They have 30 to 65 ventral grooves or pleats that extend from below the mouth to the navel area. Sei whales have a 2 foot high dorsal fin, relatively short, pointed flippers and a single ridge along the rostrum ( top of the head ). Sei whales can be confused with Bryde's whale which possess 3 ridges along the rostrum. Sei whales can attain speeds of 35 mph or 56 kilometers per hour. Being up to 60 feet in length, the Sei whale can weigh 100 thousand pounds or 45 thousand kilograms. Sei whales can live for seventy years.
Slender and elongated, fin whales are sleek and streamlined with a flat V-shaped head and up to 100 ventral grooves (pleats) extending to the navel. Fin whales have a distinctly ridged back from dorsal fin to flukes, earning them the name razorback.
