Spotting the “small eyes”: using photo-ID methodology to study a wild population of smalleye stingrays (Megatrygon microps) in southern Mozambique
Guillaume Rieucau –– This study demonstrates that the natural spot patterns of small eye stingrays can be employed to accurately identify free-ranging individuals offering novel directions of research aiming at building a better understanding of the ecology, distribution, movement patterns and behaviors of this species.
A comparison of impact and risk assessment methods based on the IMO Guidelines and EU invasive alien species risk assessment frameworks
Xavier Pochon –– This study offers an interesting comparative analysis of impact and risk assessment methods between the International Maritime Organization (IMO) Guidelines and European (EU) invasive alien species risk assessment frameworks.
A behavioral and genetic study of multiple paternity in a polygamous marine invertebrate, Octopus oliveri
James Reimer –– As the reviewers have noted, one of the few examples of examining the relationship between mating behavior and fertilization patterns in octopus.
Antioxidant enzyme cycling over reproductive lunar cycles in Pocillopora damicornis
Linda Kelly –– Provides a novel diagnostic to evaluate coral physiology and stress biomarkers
Composition and dynamics of the bacterial communities present in the post-slaughter environment of farmed Atlantic salmon (Salmo salar L.) and correlations to gelatin degrading activity
Konstantinos Kormas –– Addressing the importance of microbiota in the fish processing environments.
Recommendations for dietary level of micro-minerals and vitamin D3 to Atlantic salmon (Salmo salar) parr and post-smolt when fed low fish meal diets
Rogerio Sotelo-Mundo –– Mineral nutrition is a key aspect of fish aquaculture, and this paper addresses key aspects of micro minerals and vitamin D3 requirements in salmon.
Dietary supplementation of black soldier fly (Hermetica illucens) meal modulates gut microbiota, innate immune response and health status of marron (Cherax cainii, Austin 2002) fed poultry-by-product and fishmeal based diets
Konstantinos Kormas –– One of the very few papers dealing with meal substituition in reared freshwater crustaceans.
Clarifying a trophic black box: stable isotope analysis reveals unexpected dietary variation in the Peruvian anchovy Engraulis ringens
James Reimer –– As one of the reviewers stated, "Deepens the knowledge, although on microscale, about the trophic complexity of the Humboldt current system" with regards to an important commercial fish species, the Peruvian anchovy.
Alternative bait trials in the Barents Sea snow crab fishery
Magnus Johnson –– This paper is likely to attract some attention, and hopefully stimulate some discussion, given the potential controversy over using mammal waste as bait for crustaceans.
Towards an in-depth characterization of Symbiodiniaceae in tropical giant clams via metabarcoding of pooled multi-gene amplicons
Robert Toonen –– A new pooled multi-gene sequencing approach using three targeted amplicon markers (ITS-2, 28S LSU & chloroplast 23S) for evaluating the diversity of Symbiodiniaceae in a given holobiont sample. This method is readily scalable and offers improved resolution for roughly equivalent costs, making it a highly attractive tool for the study of symbiont diversity.
