Lack of Compliance in Gillnet Fisheries Regulations Increases Risk to a Vulnerable Species

open access: yesFisheries Management and Ecology, EarlyView.
ABSTRACT This article presents an analysis of regulatory compliance in a Brazilian gillnet fishery, based on Vessel Monitoring System (VMS) tracking data. Satellite transmissions records, interpreted as proxies for gillnet haulings events, were analyzed and classified using a neural network to assess the level of compliance of the gillnet fleet.

Mesoscale Oceanographic Processes Drive the Seasonal Abundance of the Seabob Shrimp Xiphopenaeus spp. on the Eastern Brazilian Shelf

open access: yesFisheries Oceanography, EarlyView.
ABSTRACT The seabob shrimp (Xiphopenaeus spp.) is a primary fishery resource in Brazil, with considerable economic and social importance along the coast. While environmental drivers of its life cycle are well‐documented for southeastern and southern populations, the factors modulating populations in the Eastern Brazilian Shelf remain poorly understood,

First Record of Arrhenophagus chionaspidis Aurivillius (Hymenoptera: Encyrtidae) Parasitizing White Mango Scale in Kenya: Its Potential Distribution and Prospects in Biocontrol

open access: yesJournal of Applied Entomology, EarlyView.
ABSTRACT The white mango scale, Aulacaspis tubercularis Newstead (Hemiptera: Diaspididae), is one of the most destructive pests of mango worldwide. Its current management in most of the invaded areas largely depends on the intensive use of chemical insecticides.

DNA barcoding uncovers two putative new species in Trachelyopterus (Siluriformes: Auchenipteridae)

open access: yesJournal of Fish Biology, EarlyView.
Abstract Trachelyopterus is a cryptic genus within the Neotropical catfish family Auchenipteridae with a complex history of taxonomic revisions. Despite the notable morphological and genetic similarities among its species, some studies suggest that the genus harbours greater diversity than is currently recognized, including additional species yet to be

A new sexually dimorphic species of the armoured catfish genus Neoplecostomus (Siluriformes: Loricariidae) from Neotropical Atlantic coastal drainages

open access: yesJournal of Fish Biology, EarlyView.
Abstract A new species of the small‐sized armoured catfish genus Neoplecostomus is described from Neotropical Atlantic coastal drainages, in southeast Brazil. The new species can be readily diagnosed from all congeners by having the first plates of the ventral series reduced in size, rounded and ventrally displaced, resulting in a naked band between ...

Four New Species and Records of Chaetozone Malmgren, 1867 (Annelida: Cirratulidae) from Brazilian Waters

open access: yesDiversity
Cirratulid polychaetes are abundant, ecologically relevant, and widely used as bioindicators, but systematic studies worldwide remain scarce due to systematic challenges. Chaetozone Malmgren, 1867, is the most diverse genus of Cirratulidae.

Ontogenetic Development of Hyperostosis in the Crevalle Jack Caranx hippos (Linnaeus, 1766) and New Records of Affected Bone Regions

open access: yesJournal of Fish Diseases, EarlyView.
ABSTRACT Hyperostosis is a non‐pathological condition widely reported in marine teleosts, yet its developmental dynamics and underlying drivers remain poorly understood. This study investigates the ontogenetic progression and anatomical distribution of hyperostosis in Caranx hippos based on a growth series of 39 specimens collected along the Brazilian ...
