Exploring the Structure of Static Net Fisheries in a Highly Invaded Region: The Case of Rhodes Island (Eastern Mediterranean)
Experimental fishing was conducted in three different locations along the coastal marine waters of eastern Rhodes Island, Levantine Sea, Hellas, from April 2021 to March 2022 on a monthly basis. Twelve samplings with gill nets and 12 with trammel nets at each of three selected locations resulted in a total of 72 samplings.
Assessing the Toxicity of Lagocephalus sceleratus Pufferfish from the Southeastern Aegean Sea and the Relationship of Tetrodotoxin with Gonadal Hormones
Given the dramatic increase in the L. sceleratus population in the southeastern Aegean Sea, there is growing interest in assessing the toxicity of this pufferfish and the factors controlling its tetrodotoxin (TTX) content. In the present study, liver, gonads, muscle and skin of 37 L. sceleratus specimens collected during May and June 2021 from the island of Rhodes, Greece, were subjected to multi-analyte profiling using liquid chromatography-tandem mass spectrometry (LC-MS/MS) in order to quantitate TTX and evaluate whether this biotoxin interrelates with hormones.
First record of Arcania brevifrons Chen, 1989 (Decapoda; Leucosiidae) and further record of Macrophthalmus (Macrophthalmus) indicus Davie, 2012 (Decapoda; Macrophthalmidae) in Hellenic waters
Two individuals of the introduced macrophthalmid M. (M.) indicus were found in the stomachs of silver-cheeked toadfish (Lagocephalus sceleratus), a fish species that itself is invasive. For both species, DNA barcoding was performed using the standard mitochondrial marker cytochrome c oxidase subunit I (COI).
