Are tourists keeping Costa Rican dolphins awake?
Dolphins need protected areas and times.
Recent research on Hawaiian spinner dolphins indicates that they need protected times and places. Surprise! One bay is visited by as many as sixty swimmers at a time who try to play with a small group of dolphins. Seems the dolphins rest in the early daylight hours, and that’s when many swimmer tourists head out. Less dolphins may come into the bay and the dolphins might leave earlier than usual when too many people show up. Spinners in Hawaii rest in small groups near shore in shallow sandy bays near deep water. Scientists say these places need protection. Clearly tourists should be told to leave the dolphins alone in the early daylight hours and fishing and extraction should be stopped in the bays. Costa Rican dolphins should have it so good.
Costa Rican spinner dolphins deal with giant nets towed by ships, helicopters dropping bombs, long lines full of hooks, shrimp trawlers bulldozing the bottom, surprise drill ships making a big mess, big banging seismic surveys, cargo ships blitzing by, sport fishers plowing through the pod with lines and hooks, tourist boats gawking, and even some divers in the water. How do you think that effects their beauty sleep? Future offshore Osa gold mining or other drilling might cause them even bigger problems. Offshore Osa likely has a lot of gold. The worlds first offshore gold mining operation was off of Sirena, in Corcovado National Park. Since the park is protected a measley 500 meters offshore, seems like someone might have been thinking about big gold in the deep blue sea of the Osa peninsula.
Don't forget here in Costa Rica spinner dolphins have no protected place at all.
Costa Rican spinner and spotted dolphins, who also rest in the early daylight, need tourists to leave them alone at this time. Sport fishing boats need to stop fishing in the dolphins as they particularly like the early hours of the day. Many hotel managers want tours to leave early to get everyone out of the hotel, but this is the wrong strategy if you are concerned about dolphins. Tourist operators like divers and fishers should put up on their web pages that they leave the dolphins alone in the am. Guests of Costa Cetacea over the years will recall that all tours leave late and respect the dolphins rest time, much to the frustration of some hotel managers. The interactions here in Costa Rica are much more interesting in the PM anyway.
Aloha to the Hawaiians for once again being the world ocean leaders. Lets hope Costa Rica follows.
