Freshwater turtles may ingest baited fish hooks because many are opportunistic scavengers. Although the ingestion of fish hooks is known to be a source of mortality in multiple vertebrate groups, the prevalence of hook ingestion by freshwater turtles has not been well studied. We trapped turtles from five rivers in the southeastern United States and used radiographs to examine over 600 individu...

During Drosophila embryogenesis the CNS midline cells have organizing activities that are required for proper elaboration of the axon scaffold and differentiation of neighboring neuroectodermal and mesodermal cells. CNS midline development is dependent on Single-minded (Sim), a basic-helix-loop-helix (bHLH)-PAS transcription factor. We show here that Fish-hook (Fish), a Sox HMG domain protein, ...

Accidental ingestion of fish hooks is common among turtles. Several techniques are available for retrieving hooks, ranging from simple non-invasive to more complicated and invasive surgical procedures. The purpose this case report document the successful retrieval an oesophageal foreign body (fish hook) using a minimally oesophagotomy technique (MIOT) in Indian Flap-shell turtle (Lissemys punct...

This article has been peer reviewed. Fishing is a popular rural recreational activity involving millions of Canadians. Rural physicians can expect to see the occasional patient presenting with penetrating tissue trauma involving fish hooks. Management of an embedded hook includes taking a careful history, doing a physical examination of the hook injury and surrounding tissue and preparing the s...

This study assessed the mortality of 157 snapper Pagrus auratus (9-29 cm, total length, L(T) ) after being conventionally angled and then released into cages (along with 48 controls) for 4 days off south-eastern Australia. Fatalities were restricted to 12 angled fish (7·6%) and mostly attributed to the ingestion of hooks and especially their subsequent removal, which caused substantial blood lo...

The Pacu Piaractus mesopotamicus is the most captured fish species in the Pantanal, Mato Grosso do Sul State, and since 1994, its maximum sustainable yield had already been exceeded. Its capture is carried out only by hooks, as mesh gears are forbidden either for professional or for recreational fishing. The aim of this study was to determine selectivity for different hook sizes used in P. meso...
