Abstract

Representatives of the Carcharhiniformes order frequently are associates to the incidents of sharks against the human beings, particularly in Pernambuco, where in the period of January of 1992 the September of 2004 46 attacks for sharks for the CMIT had been confirmed (Committee of Supervising incidents of sharks); two species of this order have been related with these attacks: Charcarhinus leucas (Valenciennes, 1839) and Galeocerdo cuivier (Perón & Lê Sueur, 1822), taking in consideration biological aspects of these species and information based for found teeth formula of identification of Sharks for the tooth number.

The Firemen Department, through its Maritime Grouping of Firemen (GBMar), comes being set in motion when of the capture of sharks for popular, which for many times deliver these animals for guard in the physical dependences of the this Grouping.

The present work aims at to describe 16 animals of this order being related them with the possibility to offer or to not risk to the users of beaches of the Metropolitan Region of Recife.

Of the nine listed species, all had been acquired of some places of the related area, verifying themselves, beyond other data that:

Carcharhinus acronotus (Poey, 1860) had reached 06% of frequency;
Carcharhinus falciformes (Bibron, 1839) with 19%;
Charcarhinus leucas (Valenciennes, 1839) with 25%;
Carcharhinus limbatus (Valenciennes, 1839) with 06%;
Carcharhinus obscurus (Sueur Reads, 1818) with 13%;
Carcharhinus porosus (Ranzani, 1839) with 06%;
Galeocerdo Cuvier (Perón & LeSueur, 1822) with 06%;
Sphyrna lewini (Griffith & Smith, 1834) with 13%; and
zygaena Sphyrna (Linneaus, 1758) with 06%.

We detach despite of 16 studied specimens only 02 they had presented total length and age that possibly could for in the physical integrity of the users of the Metropolitan Region of Recife (RMR); e, that ahead of the inexistence of immediate methods to mitigate the problem however in question, the prevention continues being the form less onerous and of bigger efficiency to diminish the incidents provoked for sharks.

Learning Outcomes
  1. Percentage of the captured and collected sharks in the Maritime Grouping that effectively was related with attacks against swimmers in beaches of Recife, Pernambuco-Brazil.
  2. Comparative study of the injury provoked by sharks in beaches of Recife users, about the indices of survival and deaths.
  3. Prevention and aid adopted by the Fireman Department of Pernambuco against the attacks of sharks.
