Procedure for Collecting Gastric Contents in Giant Amazon Turtles Podocnemis expansa (Schweigger, 1812)(Testudines, Podocnemididae)
(Brazilian Journal of Veterinary Pathology, 2024-09-12)
describes a method for collecting gastric contents from giant Amazon turtles (Podocnemis expansa) for research and conservation purposes. The procedure involves immobilizing the turtle on its back for the collection. A "mouth opener," made of a plastic tube with a flexible part, is used to keep the turtle's beak open while a flexible probe is introduced. After injecting a sterile saline solution and air, the gastric contents are aspirated. The size of the mouth opener and probe must be adjusted to avoid injury, and the volume of liquid must match the stomach’s capacity. This method, developed by the research team, effectively helps in identifying parasites and infectious microorganisms.

Reducing threats to turtles.
(1999) MARCOVALDI, M. Â. G. dei; THOMÉ, J. C. A.; ECKERT, K. L; DONNELLY. M; ABREU-GROBOIS, F. A; BJORNDAL, K. A
Around the world, the survival of seven species of sea turtle is threatened by a variety of man-induced factors, including the direct and indirect harvest of adults and juveniles (see Oravetz, this volume), threats to eggs and hatchlings (see Boulon, this volume; Mortimer, this volume), the degradation or loss of nesting habitat (see Witherington, this volume), and pollution of the seas (see Gibson and Smith, this vol ume). Perhaps no threat is as pervasive and devastating to declining populations as the persistent take of adult and juvenile turtles. The take continues, often in contravention of existing national and international legislation, largely because of familiar and ineffective "top-down" approaches to conservation, and a lack of grassroots support for or understanding of conservation initiatives. In response, conservation organizations and regulatory agencies alike are investing heavily in community-based conservation (see Frazier, this volume). Community-based conservation involves changing habits and outlooks, neither of which happens easily.
