RESUMO: A ostreicultura vem se desenvolvendo nos últimos anos, porém, para o sucesso desse cultivo, é necessário compreender como os fatores abióticos, por exemplo, temperatura e salinidade, afetam o seu crescimento. O presente estudo objetivou analisar o efeito da sazonalidade amazônica no crescimento de ostras Crassostrea tulipa (Lamarck, 1819) c...

In the study, we compare the shell shape morphometrics in four species of neritid gastropods ( Nerita fulgurans , Nerita tessellata , Nerita peloronta and Nerita versicolor ), collected in Accra Beach (Barbados Island). We tested the hypothesis that the morphometric ratios can be used as a tool in the taxonomic determination among these four specie...

Abstract In the last decades the oyster faming stands out as the main mitigating measure to the decline of the fishery, as it presents socio-economic and environmental viability. However, for the success of the activity, it is necessary to understand the stages of cultivation, as well as the growth performance of the species to be cultivated. The p...

Marine gastropods of the family Naticidae are worldwide distributed and known for their unusual predatory habits. Due to their wide distribution, the naticids are worldwide studied and known like predators of intertidal bivalves. The present study demonstrates the predation of the naticid gastropod Natica marochiensis on the bivalve Donax striatus...

Sphenia fragilis é um molusco bivalve pertencente a família Myidae, que possui hábito de escavar e viver alojado em espaços livres, cavidades e/ou fendas deixadas por outros organismos (e.g., mexilhões e ostras). A espécie apresenta elevada variação morfológica na forma da concha, no entanto, no entanto, ainda não foi estudado essa variação a parti...

O biofouling é um dos principais problemas que acometem cultivos de ostras. Neste estudo, objetivou-se testar a hipótese de que a riqueza e a abundância do macrobentos que compõe o biofouling estão associadas à área de superfície da ostra Crassostrea tulipa cultivada no rio Urindeua, Pará. Para tanto, realizaram-se nove coletas entre maio de 2016 e...

The present study focuses on the distribution and abundance of the giant isopod community, based on specimens collected using the bottom shrimp trawling on the Amazon continental shelf during fishery surveys, at depths between 81 m and 626 m, conducted during the REVIZEE/Score-North Program between 1996 and 1998. The study area is located within th...

Os recursos pesqueiros (e.g., peixes, crustáceos e moluscos) compõem a dieta alimentar das populações, pois representa uma fonte de proteína. Neste contexto, os moluscos bivalves apresentam elevada importância ecológica e socioeconômica, principalmente para comunidades que vivem as margens dos rios. Desta forma, o presente trabalho registra a utili...

The widespread occurrence of marine gastropods in coastal regions is a straightforward evidence of successful adaptation to different environments. In the Caribbean Sea, as one of Conservation International’s biodiversity hotspots, little is known about the gastropod fauna, especially in the Eastern Caribbean.

A ostreicultura surge no contexto mundial como uma das alternativas mais viáveis ao declínio da pesca e o fornecimento de recurso alimentício fresco. No Brasil, cultiva-se ostras do gênero Crassostrea e, no estado do Pará, cultiva-se a Crassostrea tulipa, conhecida por ostra-do-mangue. O presente estudo tem como objetivo caracterizar a biomorfometr...

Biofouling affects global aquaculture with significant impacts on productivity and profitability, especially in marine shellfish culture, where both the target culture species and/or infrastructure are exposed to a diverse array of fouling organisms. In oyster culture, fouling of stock causes physical damage, mechanical interference, biological com...

Resumo-O desenvolvimento da ostreicultura no estado do Pará depende da produção e da coleta de sementes no meio ambiente, que não é continua ao longo do ano, na área estudada. O que torna necessário a indução à desova das ostras em condições laboratoriais. Neste estudo, foram avaliados os seguintes métodos simples e de baixo custo: (1) choques físi...

Macroecology provides a novel conceptual framework for analysis of the distribution and abundance of organisms at very large scales. Its rapid development in recent years has been driven primarily by studies of terrestrial taxa; the vast potential of marine systems to contribute to the macroecological research effort remains largely untapped. Inter...

This study examines whether or not biogeographical and/or managerial divisions across the European seas can be validated using soft-bottom macrobenthic community data. The faunal groups used were: all macrobenthos groups, polychaetes, molluscs, crustaceans, echinoderms, sipun- culans and the last 5 groups combined. In order to test the discriminati...

We describe an integrated database on European macrobenthic fauna, developed within the framework of the European Network of Excellence MarBEF, and the data and data integration exercise that provided its content. A total of 44 datasets including 465 354 distribution records from soft-bottom macrobenthic species were uploaded into the relational Ma...

Local species diversity may be determined by processes operating locally, such as disturbance, predation and competition, or by regional processes, such as environmental structuring or history. Classical theory focusing on competition predicts that the species combining to form communities will be less similar to each other than they would be if th...

The pan-European MacroBen database was used to compare the AZTI Marine Biotic Index (AMBI) and the Benthic Quality Index (BQIES), 2 biotic indices which rely on 2 distinct assessments of species sensitivity/tolerance (i.e. AMBI EG and BQI E[S50]0.05) and which up to now have only been compared on restricted data sets. A total of 12 409 stations wer...

The macrozoobenthos (5-30m depth) of Kongsfjord (Svalbard) was quantita- tively investigated by a SCUBA-diver operated airlift system. 63 taxa were found, 30 of which were not reported for Kongsfjord and seven not for Sval- bard before. Suspensivorous or surface and sub-surface detritivorous poly- chaetes and deposit-feeding amphipods were dominant...

There is much speculation about the easternmost distribution of Alloteuthis subulata. It is very common in the North Sea and regularly, although not abundant, occurring in the Kattegat, whereas recordings from the Baltic Sea are sparse and mostly anecdotic. Here we report on an unusual collection of 18 specimens which were sampled in January 2001 i...
