First Time

Data obtained from licenses of spearfishers and surveys conducted in 2004 and 2017 allowed for the analysis, for the first time, of the practice of spearfishing in the Madeira archipelago. Only a small percentage of the population practices spearfishing, mostly local young men. Most of them practice the activity with a partner throughout most of the year and along most of the island's coastal areas, although preferentially along the North and Southeast coast. Results show how, in recent years, despite the population of spearfishers decreasing, the abundance in the annual catch potentially increased, probably due to the higher investment of time in this activity. It has been observed that many fishers complement their catches with manual collecting of invertebrates. Overall, 40 teleost fishes and also 4 crustaceans and 8 molluscs were identified. The most frequently captured fish species were parrotfish and white seabream, while limpets were the most collected invertebrates in both selected periods.

A series of diazenyl chalcones was prepared by base catalyzed Claisen-Schmidt condensation of synthesized hydroxy substituted acetophenone azo dye with various substituted aromatic/ heteroaromatic aldehydes. The structural conformation of synthesized chalcones was done by a number of physicochemical and spectral means like FTIR, UV-visible, mass, NMR spectroscopy and CHNS/O analysis. These diazenyl chalcones were assessed for their in vitro antimicrobial potential against several Gram-negative, Gram-positive bacterial and fungal strains by serial tube dilution method. The fluconazole and cefadroxil were used as standard drugs. The target compounds were also evaluated for their antioxidant potential by DPPH assay. (2E)-3-(2,4-Dichlorophenyl)-1-(4-((2,6- dihydroxyphenyl)diazenyl)phenyl)prop-2-en-1-one (C-7) had shown very good antimicrobial potential with MIC ranges from 3.79 to 15.76 μg/ml against most of the tested microorganisms. Most of the synthesized diazenyl chalcones were found to be active against B. subtilis. The (2E)-1-(5-((2-Chloro- 4-nitrophenyl)diazenyl)-2-hydroxyphenyl)-3-(2-hydroxynaphthalen-1-yl)prop-2-en-1-one (C-10) had shown high free radical-scavenging activity when compared with the ascorbic acid as the reference antioxidant.

AbstractFifteen attached macroalgae from the Madeira Archipelago, comprising three green, three red and nine brown algal species, as well as two beach-cast macroalgal samples, collected along the north shore of Gran Canaria, were assessed for their biochemical properties. The analysis included the determination of total minerals, total carbohydrates, protein, lipids, chlorophyll a, total carotenoids, total phenolic content, fucoxanthin and phycobilins (allophycocyanin, phycocyanin and phycoerythrin). The results showed a high variability of biochemical composition, allowing for the targetting of specific bioresources for particular purposes, including functional foods. This work provides the foundation for a biorefinery strategy implementation plan, for which specific macroalgae may be targeted for valuable and beneficial compounds.
