Abstract This study examined the presence of Salmonella spp. in fresh frog meat and freeze-dried seasoned stored for up to 90 days at room temperature. The samples were analyzed triplicate using conventional official method, by polymerase chain reaction (PCR) mass spectrometry technique (MALDI –TOF) — a comparison results obtained three tested methods. Mass analyses confirmed 100% samples. In analysis percentages detection 67% B2 B3, whereas PCR method indicated bacteria respective none...

Ballast water is used by ships to ensure their operational safety and stability. However, the use of seawater as ballast can cause dispersal exotic marine species. Native species from other regions be transported, causing serious socio-environmental economic consequences, due interaction with local The present study aimed record occurrence bivalve mussel Perna viridis, produced, collected sold in city Niterói, Rio de Janeiro, Brazil. This mollusc originating Asia now abundant Guanabara Bay,...

The present study identified the occurrence hyperostosis specimens Leatherjacket Oligoplites saurus, an important commercial species, using radiographic images. Biometric measurements four were performed and affected detected different levels regions skeleton: Supraoccipital, Pterygiophores, Cleithrum, Hemal Spines Neural Spines. Bones with...

Abstract Hyperostosis manifests itself and develops differently in taxonomically related species. Radiographic images of individuals belonging to different size classes Atlantic Moonfish Selene setapinnis Lookdown vomer were obtained from two estuarine areas Rio de Janeiro/Brazil. In S. , hyperostosis occurred 65.22% the specimens analyzed three skeletal regions. All had four Patterns occurrence detected both species, affected regions did not coincide same bone region, except for cleithrum....

Due to their commercial importance, this study aimed monitor hygiene and sanitary quality Perna mussels (Linnaeus, 1758), from farming extractivism Jurujuba, Boa Viagem Centro, Niterói, Rio de Janeiro, Brazil. Collections were carried out once a month, January December 2022, 1,080 animals, for bacteriological evaluation by MPN coliforms at 35°C, 45°C Escherichia coli, according “Fluorocult LMX”...

Abstract The aim of this study was to investigate the effect ultraviolet ( UV )‐ C treatment on decrease inoculated S taphylococcus aureus population in precooked shredded bullfrog meat. meat with 8 log cfu/g . packaged bullfrog's back then exposed low (0.65 m W /s/cm 2 ), medium (1.04 ) and high (1.68 ‐ intensities over different time intervals (60, 100 140 s). A reduction 3 observed all treatments when compared but nonirradiated T 0). All used reduced count P < 0.05). However, not...

This study investigated the depuration time of tilapia in saline and freshwater environments its influence on animal performance meat quality. Depuration until seventh day resulted significant reductions average weight, condition factor, viscerosomatic index, hepatosomatic index fillet yield both environments. Regarding proximate composition, environment promoted maintenance crude protein, moisture ash percentages. reduced percentages energy increased humidity. Total lipids were...

Abstract Marine teleost species of commercial interest are often reported with hyperostosis, an osteological condition that results in bone thickening. Various specimens Atlantic Spadefish Chaetodipterus faber ( n = 86) obtained from artisanal fishermen Rio de Janeiro, Brazil, were radiographed and assessed to detect the occurrence hyperostosis across four different size classes. Of examined individuals, 58.62% displayed signs which manifested eight skeletal regions, notably supraoccipital...

The decreasing stock of the main species consumed in Brazil has stimulated studies regarding use and development products using low commercial value species. shrimp trawling modality produces a large volume "mix" category comprising fish. However, it is necessary to develop with greater practicality meet current demands Brazilian consumer. aim present study was sausage fish, flathead (Percophis brasiliensis ), caught fish landed Niterói/RJ, perform physico-chemical, microbiological,...

Cortes histológicos de 120 mexilhões Perna perna (Linnaeus, 1758), coletados na Lagoa Itaipu, Niterói, RJ, por um período 12 meses, foram examinados quanto a presença parasitas e lesões. Noventa exemplares apresentaram cinco diferentes processos patológicos: bucefalose, protozoários Nematopsis sp., inclusões basofílicas não específicas, encapsulamentos parasitários cistos epiteliais branquiais. Cinquenta animais mostravam duas ou mais patologias concomitantes.

Willing to increase the shelf life of food matrix, studies regarding new preservations methods are developed preserve fish deterioration. The application natural additives as preservatives is increasingly common, with a current emphasis on growing use protein hydrolysates, in substitution artificial ones. These compounds have been subject recent studies, focusing determining their functional properties and best form applying peptide chains. present study aimed evaluate effects hydrolysate...

ABSTRACT The occurrence of hyperostotic bones is common in marine fish, especially the Carangidae family, despite few records this condition fishes from Brazilian waters. present study describes hyperostosis Atlantic moonfish (Selene setapinnis) in, Rio de Janeiro State, Brazil. Radiographs fish specimens were taken and all them presented at least three different regions: cleithrum, pterygiophores pleural ribs. observed pattern previously described for other species same genus. It first...

RESUMO Na pesca de arrasto, são inúmeras as espécies peixe capturadas acidentalmente, compostas, em sua maioria, espécimes pequeno tamanho e baixo valor comercial, os quais recebem o nome rejeito pesca. O presente trabalho teve como objetivo desenvolvimento dois produtos, almôndega quibe peixe, tendo matéria- prima consideradas capturas acidentais na modalidade arrasto realizada no litoral do Rio Janeiro. A identificação taxonômica das resultado pargo (Pagrus pagrus), castanha (Umbrina sp.),...
