Morigenos and Bananko sighted after a long time

Yesterday and today, just off the coast of Fiesa and Piran, we encountered Morigenos and Bananko, two male dolphins we know well. We first met Morigenos in March 2003, while Bananko was first seen in July 2004. Both of them are among the most commonly observed dolphins in Slovenian waters, as well as in the Gulf of Trieste in general.  We last saw them in August 2020. During this autumn-winter period we spent less time in the field, due to both weather conditions and the situation related to covid-19, so we have not seen some of our studied dolphins for a while. That is ...

DOLPHINS IN THE MIST

Our dolphin searching skills have reached a new level! Today we managed to locate a group of dolphins in almost zero visibility, using only sound. We headed out to sea at dawn in very dense fog, with visibility of less than 50 m. These aren’t conditions in which we would typically conduct fieldwork, but due to recent sightings we decided to go out regardless. Soon after we left the harbour, we stopped the boat and put our hydrophone in the water. Sure enough, we detected dolphin whistles almost immediately. Using both intuition and successive detections of dolphin ...

THIS IS HOW PIRAN BAY SOUNDED TODAY

The waters around Piran were pretty noisy today. These are the sounds of 35-40 dolphins, including males, females and calves, recorded by Morigenos research team using a hydrophone (underwater microphone). The Gulf of Trieste, including the waters of Slovenia, is home to a resident population of about 150 bottlenose dolphins (Tursiops truncatus). Dolphins use these waters to feed, reproduce and raise their young. This population has been studied by Morigenos researchers for 18 years, so we know most of these dolphins well. Individual animals are identified by natural ...

First sighting in 2021

Yesterday we had our first dolphin sighting of 2021, thanks to a call we received early in the morning. Our team immediately headed out to sea and soon located a group of about 30 dolphins, which spent almost two hours around Piran, predominantly feeding. At Morigenos we know these dolphins very well, some of them for 18 years. The group included males and females with calves. We are always glad to receive such calls, so we invite everyone to report their dolphin sightings in the Gulf of Trieste to us on +38631771077. This helps us collect important information about the ...

Ocean giants visit the Gulf of Trieste

Today, Morigenos researchers located and observed two fin whales (Balaenoptera physalus), thanks to a report by one of Slovenian fishermen. The fin whale is the second largest animal on our planet and the only regularly present baleen whale in the Mediterranean Sea. In the northern Adriatic Sea this species is typically recorded every few years. Fin whales in the northern hemisphere grow up to 22.5 m and 50 tons, while their southern hemisphere counterparts can grow up to 26 m and 80 tons. They mainly feed on small crustaceans called krill, and on some small fish species. ...

THE UNCOMMON COMMON DOLPHIN

Morigenos has published a new review study on the occurrence of common dolphins in the Gulf of Trieste and the northern Adriatic Sea, published this week in the renowned scientific journal Aquatic Conservation: Marine and Freshwater Ecosystems. The common dolphin (Delphinus delphis) used to be very common in the Adriatic Sea and other parts of the Mediterranean Sea. However, from the 1970s onwards it had become so rare that the Mediterranean population is now listed as Endangered on the Red List of the International Union for the Conservation of Nature (IUCN). The dolphin ...

New study on feeding ecology of dolphins in Greece

Morigenos participated in a study investigating the feeding ecology of dolphins in the Gulf of Ambracia in Greece, led by researchers from the University of Barcelona and Tethys Research Institute and published this week in the journal Marine Mammal Science (https://onlinelibrary.wiley.com/doi/abs/10.1111/mms.12725). The almost completely enclosed Gulf of Ambracia, in northwestern Greece, hosts a threatened community of about 150 bottlenose dolphins, which are largely separated from neighbouring populations in the Ionian Sea and are being studied by Tethys Research ...

Acoustic monitoring

Finally, our acoustic equipment is back, safe and sound (no pun intended)! After a combination of reasons related to the COVID-19 situation prevented us from retrieving our acoustic loggers as originally scheduled, we were forced to leave them in the sea longer. We were happy and relieved to find they were still there. We look forward to analysing the collected data!

Master thesis on the impacts of fisheries on dolphins in the Gulf of Trieste

  Huge congratulations to Janja Hozner, a friend and former participant to our research courses, who got awarded her MSc degree with distinction in Biology and Ecology with Conservation at the University of Maribor, with a thesis titled “Impact of fisheries on the behaviour and body injuries of bottlenose dolphins (Tursiops truncatus) in the Gulf of Trieste”, carried out in collaboration with Morigenos. Well done Janja!
