“…Studies on the occurrence of cetaceans around the world are made using different methodologies such as: strandings, historical records, opportunistic sightings, and dedicated surveys ( Maldini et al 2005 , Lucena 2006 , Toledo and Langguth 2009 , Ramos et al 2010 , Authier et al 2014 , Prado et al 2016 ). In other words, cetacean composition in a specific area could be assessed through strandings when other sources of information are not available ( Maldini et al 2005 , Byrd et al 2014 , Jung et al 2015 ).…”

Marine mammal stranding events are used as an important tool for understanding cetacean biology worldwide. Nonetheless, there are vast gaps of knowledge to be filled in for a wide range of species. Reputable information is required regarding species from large baleen whales to sperm and beaked whales, as well as pelagic dolphins. This paper describes new cetacean records from north and north-eastern Brazil, which are both the least surveyed areas regarding aquatic mammals. Regular beach surveys were conducted to recover cetacean carcasses along the coast of Pará beginning November 2005. At the coasts of the Maranhão and Piauí states, the surveys were conducted between 2003 and 2013. From 2003 to 2014, 34 strandings of cetaceans were registered. The study provides four additional species records’ in the area based on strandings (Balaenoptera borealis, Balaenoptera physalus, Peponocephala electra, and Pseudorca crassidens). A mass stranding of Guiana dolphins (Sotalia guianensis, N = 12), the most common species for the region, was reported for the first time. The records presented herein are of special concern, since they expand the knowledge on cetaceans from the Brazilian coast. In addition, this study conducted an analysis to verify the similarity between cetacean compositions described for north and north-eastern Brazil and the southern Caribbean region. The results showed a high similarity between these regions, proving the connection with the Caribbean cetacean fauna.

“…The pre-modern whaling techniques used at the armações imposed restrictions on the species that could be captured by the whalers. In addition to southern right whales, only two other species could be exploited in Brazil: humpback whales Megaptera novaeangliae and sperm whales Physeter macrocephalus (Lodi 1992, Toledo & Langguth 2009, Ellis 2011. The only record of sperm whales being processed at armações was of six individuals captured by the North American brig Leviathan (Ellis 1969).…”

From the southern right whale hunting decline to the humpback whaling expansion: a review of whale catch records in the tropical western South Atlantic Ocean

Historical catch records from whaling activity are crucial for assessments of whale populations. However, several gaps in the exploitation history for many populations from before the twentieth century create limitations that may lead to overestimates of the recovery of these populations. The history of modern whaling along the Brazilian coast is relatively well known. However, several questions relating to the pre‐modern period, during and before the nineteenth century, remain unanswered. For example, the level of exploitation of humpback whales Megaptera novaeangliae and southern right whales Eubalaena australis in this period is unknown. Pre‐modern whaling in Brazil began in 1602 and lasted until the 1920s. Whales were captured using manual harpoons from either rowing boats or sailing boats, and processed at land stations called ‘armações’. A review of the history and oil production of these stations indicates that substantial catches occurred. Pre‐modern whaling records also indicate the collapse of the southern right whale population in the western South Atlantic Ocean. Increasingly rare reports of sightings for the nineteenth century and the closing of the last armação in the breeding grounds off southern Brazil indicate that this population collapsed by 1830. Armações operating in north‐eastern Brazil remained active through the 1800s, and targeted humpback whales until modern whaling techniques were introduced in the early 1900s. It is estimated that between approximately 11000 and 32000 individuals of this species were captured at these coastal whaling stations from 1830 to 1924.
