Temporal distribution of ichthyoplankton in the Ivinhema River (Mato Grosso do Sul State/ Brazil): influence of environmental variables

Neotropical Ichthyology
Information on ichthyoplankton is an important tool in determining reproduction periods that - if associated to environmental variables - allows for inferences about the factors that regulate their intensity, beginning, and ending.

Anisakis sp. larvae in Plagioscion squamosissimus (Heckel, 1840) from the Curralinho municipality, Marajó Island, Pará, Brazil

Archives of Veterinary Science
Abstract: Several reports from Brazil indicate the presence of fish parasitized by nematodes with zoonotic potential, notably those within the Anisakidae family. This research investigates the morphology, morphometry, and prevalence of Anisakis larvae parasitizing fish being sold in the municipality of Curralinho, in the Brazilian state of Pará. Twenty
