We are regularly looking for and need volunteers to strengthen our teams in South America. These people already have specialist knowledge and appropriate training and are important for the work in our species conservation projects. YAQU PACHA's aim is to employ these specialists in our projects on a long-term basis.
Observation and photo-identification of Lahille's bottlenose dolphins in the Lagoa dos Patos in Brazil with our research boat Charlotte. These trips take place on a regular basis and are very important for the assessment of the population in the Lagoa dos Patos. The photo-ID method is based on the distinguishing feature of the dolphins' dorsal fin, as this is different for each animal. This allows individual animals to be identified and the total population to be estimated. With the help of a database, the animals can be recognized and sightings registered.
A very important part of the conservation of the La Plata dolphins is the aerial surveys, which are carried out using airplanes with specially curved windows from which the animals are counted.
These flight counts were conducted in March and April 2023 along the coast of Uruguay and are crucial for determining the population of the La Plata dolphin in Uruguay.
In this way, population declines can be detected immediately, which is of great importance for a better assessment of the species' situation. The results of the flight counts are shared with the partner institutions involved in the project. Regular aerial counts are important in order to identify population fluctuations and develop new strategies to protect this most endangered dolphin species in South America. A sharp decline, as has already been observed in some populations of the La Plata dolphin further north, must be regarded as alarming.
Our teams regularly search the beaches along the Brazilian coast for stranded animals. Live animals are immediately brought to our stations in special transport boxes, where they receive immediate medical treatment and care. Dead stranded animals are also recovered to be examined and the cause of death determined.
Continuous veterinary care and treatment is crucial for the survival of the stranded and rescued La Plata dolphins. Any deterioration in their health must be recognized immediately and treated accordingly by specially trained veterinarians.
