“…A utilização destes locais por estes animais é favorecida pela presença de bancos de macroalgas (Araújo et al, 2004), fanerógamas marinhas (Lima, 1997) e organismos da meiofauna associado a estes vegetais (Oliveira et al, 2003), pois de acordo com Luna (2001), a disponibilidade alimentar influencia positivamente a presença dos peixes-boi marinhos, despertando a necessidade eminente de proteção destes ambientes.…”

“…Considerado o mamífero aquático mais ameaçado de extinção no Brasil, o peixe-boi marinho (Trichechus manatus) apresenta a sua população distribuída de forma descontínua nas regiões Norte e Nordeste (Lima, 1997;Luna, 2001). Em estudos realizados com peixes-boi marinhos na Flórida, os animais passaram até oito horas por dia alimentando-se, sendo considerados consumidores herbívoros e oportunistas (Hartman, 1979).…”

ResumoOs peixes-boi marinhos são considerados herbívoros oportunistas, consumindo uma grande variedade de itens alimentares. Objetivou-se com este trabalho identificar os itens alimentares constituintes da dieta dos peixes-boi marinhos em vida livre, na região Nordeste do Brasil. Para tanto foram coletadas amostras de conteúdo estomacal, provenientes de seis carcaças de peixes-boi marinhos, além de amostras fecais de 11 animais nativos e cinco espécimes reintroduzidos. O material foi identificado ao nível de gênero e/ou espécie, através de aspectos morfo-anatômicos, sendo identificadas 21 espécies entre macroalgas, fanerógamas e cnidários. Através destas análises, foi possível observar que os peixes-boi marinhos alimentaram-se de uma grande diversidade de plantas aquáticas, com predominância das algas vermelhas.Unitermos: mamíferos aquáticos, sirênios, macroalgas, fanerógamas, alimentação AbstractIdentification of alimentary components of Antillean manatee diet in the Northeast of Brazil. The manatees are considered to be opportunist herbivors, consuming a great amount of alimentary items. The aim of the present study was to identify the alimentary components of the diet of Antillean manatees in free life in the northeastern region of Brazil. Samples of stomach contents from six Antillean manatee carcasses were collected, in addition to fecal samples from 11 native manatees and five that had been released. The material was identified at the genus and/or species level, based on its morpho-anatomic aspects, and 21 species of seaweeds, phanerogams and cnidarians were presented. Through these analyses it was possible to observe that Antillean manatees fed on a great variety of aquatic plants, with the predominance of red seaweeds.

“…Considered to be the most endangered aquatic mammal in Brazil, the population of Antillean manatees (Trichechus manatus) is discontinuously distributed in the northern and northeastern regions of Brazil, 15,18 and the stranding of newly born calves is one of the main problems related to the conservation of this species. 19,21 Antillean manatee calves are sensitive to changes in their habitat and, therefore, the degradation of estuarine environments in the Northeastern region is identified as a triggering factor of stranding events.…”

The aim of this work was to analyze whether there are differences between the development pattern of Antillean manatee (Trichechus manatus) calves born in captivity and those rescued and kept under rehabilitation. Biometrics data were collected from 1990 to 2010 from 38 calves, 29 of which still had the remnants of the umbilical cord and had been rescued from the Brazilian northeastern coastline (Group I), and nine individuals that were born in captivity and remained with their mothers (Group II). Among the measures obtained through biometry, the total length and weight of the animal were recorded. Given that the breastfeeding of calves occurs approximately until the age of 2 yr, data obtained until the 24th month of life of each individual were evaluated. An average increase in weight of 53.50 +/- 38.54 kg (mean +/- standard deviation [SD]) was detected in Group I and a gain of 106.87 +/- 47.21 kg (mean +/- SD) in Group II. From months 13 to 24, no significant difference in the weight increment was observed. A similar pattern occurred with regard to the increase in the overall length during the first year, where animals from Group I grew 34.81 +/- 17.94 cm (mean +/- SD) and from Group II grew 83.83 +/- 28.21 cm, a statistically significant difference. The growth was not significantly different from 13 to 24 mo. The results found in this study identified the need for a review of the nutritional diet offered to orphaned calves rescued and kept in captivity. The results also support the need for a better adequacy of facilities for these animals as a way to encourage the management strategies adopted for manatee calves maintained in captivity.

“…This mammal is considered one of the most endangered aquatic mammals in Brazil and has discontinuous occurrence in the North and Northeast coast of the country (da Silva et al, 2008;Luna et al, 2008aLuna et al, , 2011. Changes in habitats, human activities, low genetic variability and high number of stranding of manatee calves have been the major problems for the conservation of the Antillean manatee in Brazil (Parente et al, 2004;Luna et al, 2008bLuna et al, , 2012Meirelles, 2008;Luna, 2013).…”
