Carapace width/length-weight relationships for portunid crabs (genus Callinectes Stimpson, 1860) in northern Brazilian mangrove estuaries [PDF]

Nauplius, 2022
Carapace width-carapace length (CW/CLRs), carapace width-weight (CW/WRs), and carapace length-weight (CL/WR) relationships are presented for the portunid species Callinectes bocourti A.

Sexual maturity of Callinectes danae and C. ornatus from Paraguaçu river estuary, Bahia state, Brazil

Boletim do Instituto de Pesca, 2022
Callinectes danae and C. ornatus are economically important species in several countries, including Brazil. Therefore, this study aimed to estimate the L50 of these species using morphological, morphometric, and physiological data.

Swimming behavior of newly hatched larvae of six decapod species (Crustacea: Decapoda)

Nauplius, 2021
Crustacean decapod larvae have developed several adaptations to maximize their survival, including swimming behavior. Swimming improves larvae dispersal and contributes to their response to environmental stresses, including variations in abiotic factors,

Species which may act as vectors or reservoirs of diseases covered by the Animal Health Law: Listed pathogens of crustaceans

EFSA Journal, Volume 21, Issue 8, August 2023., 2023
Abstract Vector or reservoir species of three diseases of crustaceans listed in the Animal Health Law were identified based on evidence generated through an extensive literature review, to support a possible updating of Regulation (EU) 2018/1882.

Amino acid nitrogen and carbon isotope data: Potential and implications for ecological studies

Ecology and Evolution, Volume 12, Issue 6, June 2022., 2022
Stable isotope analysis of individual amino acids (AAs) in natural abundance is now emerging as a promising and complementary method to characterize the flow and transformation of resources across a diversity of organisms, from microbial domains to macroscopic consumers. Many empirical ecologists are still unfamiliar with the scope of applicability and

Recent developments in male fertility evaluation, sperm cryopreservation and artificial fertilisation, and their potential application to decapod crustacean aquaculture

Reviews in Aquaculture, Volume 14, Issue 2, Page 848-889, March 2022., 2022
Abstract To maximise productivity, a better understanding of the underlying causes of subfertility that lead to inferior offspring and high mortality is imperative. In decapod crustaceans, most research has focused on female reproductive performance, with little attention given to male fertility.

Unravelling the stomach contents of fish and crab species from Cananéia, São Paulo: Are they eating plastic? [PDF]

Papéis Avulsos de Zoologia, 2023
Plastic pollution represents a threat to marine ecosystems and has therefore been gaining space in the realm of public interest. In this study, we investigated the ingestion of food and non-food items (i.e., plastic particles) by fish and crabs.

Morphology of the first zoeal stages of five species of the portunid genus Callinectes (Decapoda, Brachyura) hatched at the laboratory

Anais da Academia Brasileira de Ciências, 2014
The genus Callinectes Stimpson, 1860 currently consists of 16 species, six of which are reported in Brazilian coast. In the present study, the first zoeal stages of Callinectes bocourti,C. danae, C. exasperatus, C. ornatus and C. sapidus from Brazil were

All or nothing: Switch to high current reproductive investment under risk of starvation in male kelp crab

Ecology and Evolution, Volume 10, Issue 7, Page 3383-3391, April 2020., 2020
In this study, we demonstrate plasticity in recovery of seminal reserves in response to distinct environmental conditions in the kelp crab Taliepus dentatus. We show that the recovery index at 16°C within 30 days was twice as high in starved compared with fed crabs.
