Abstract Storing non‐marketable fish aboard fishing vessels takes up valuable storage space and, consequently, it is usually discarded. Therefore, the strategy to minimize amount of discarded and boost economy should entail measures turn unexploited species into marketable fish. The use sensory descriptive analysis first step in characterization foods assess their baseline appeal final consumer. In this study, five was conducted, using a semi‐trained panel, with objective establishing...
The most consumed fish species in Portugal do not correspond to the caught on Portuguese coast. From point of view ocean sustainability and economics, it is important study unexploited or underexploited that have potential be introduced into food market. This can reflected by their nutritional value, where mineral elements are often overlooked despite importance human health. Therefore, elemental concentration those species, which should also include seasonal variations essential such as Ca,...
We live in a world of limited biological resources and ecosystems, which are essential to feed people. Consequently, diversifying target species considering full exploitation for fishery sustainability. The present study focuses on the valorization three low commercial value fish (blue jack mackerel, Trachurus picturatus; black seabream, Spondyliosoma cantharus; piper gurnard, Trigla lyra) two unexploited (comber, Serranus cabrilla boarfish, Capros aper) through development marine-based food...
Abstract Target species diversification is essential for fisheries sustainability and fish market revitalization. Fish discards are a widely recognized problem resulting from worldwide, of major concern all sector players, administrations, to fishermen, scientists. However, non‐target seldom studied, information on nutritional profiles seasonal changes in properties generally lacking. This study assessed the composition two unexploited ( Serranus cabrilla , Capros aper ) three low commercial...
Growth modelling is essential to inform fisheries management but often hampered by sampling biases and imperfect data. Additional methods such as interpolating data through back-calculation may be used account for bias are complex time-consuming. Here, we present an approach improve plausibility in growth estimates when small individuals under-sampled, based on Bayesian fitting models using Markov Chain Monte Carlo (MCMC) with informative priors parameters. Focusing the blue jack mackerel,...
Overfishing is increasing over time, and according to FAO (Food Agriculture Organization), about one third of the world’s fish stocks are now overfished. Thus, diversifying target species essential for fisheries sustainability contributing improve resource-efficient processes. Non-target can be valuable resources development new food products. However, those scarcely studied, it high importance trace their seasonal sensory profile as a first step towards valorisation. Therefore, in this...
Blue jack mackerel, Trachurus picturatus, is the fifth most landed fish species in mainland Portugal, but information on its reproductive biology scarce. From September 2018 to August 2019, 626 specimens were collected from commercial vessels clarify strategy of T. picturatus population off west coast Portugal. The proportion and length range males females similar. Only three categorized as immature, indicating that caught fishery are primarily mature. spawning season lasted late January...
In this study, different extraction methods and conditions were used for the of antioxidants from brown macroalgae Fucus spiralis. The methodologies ultrasound-assisted (ultrasonic bath ultrasonic probe), with a vortex, an Ultra-Turrax® homogenizer, high-pressure-assisted extraction. extracts analyzed their total phenolic content (TPC) antioxidant activity, evaluated through 2,2-difenil-1-picrilhidrazil (DPPH) free radical scavenging method ferric reducing power (FRAP) assay. Ultrasonic...
ABSTRACT The depletion and overexploitation of several fish stock demands for a valorisation non‐target discarded species. Nonetheless, such species are often poorly studied, information on their biological parameters must be gathered effective population management. For 1 year, the reproductive strategy piper gurnard Trigla lyra red Chelidonichthys cuculus was studied by monthly samples obtained from commercial boats operating western Portuguese coast. Both showed biased sex ratio towards...
Reproduction of Trachurus picturatus off the western Portuguese coast was studied over 1 yr. During histological analyses, presence Kudoa sp. detected in advanced vitellogenic oocytes. infections are known to cause economic loss through induction post-mortem liquefaction fish muscles, but ovarian infection as reported this study will seriously affect reproductive potential species and thus impact fisheries productivity. Only females showed gonad which led total degradation No macroscopic,...
Gurnards are a valuable by-catch of mixed demersal fisheries and commercially important in European waters, but they often discarded, reported under “mixed gurnards” with incomplete biological information by species. In the present work, total 558 piper gurnard specimens between 10.9 44.4 cm (1 to 11 years) 425 red 10.2 42.1 (0 9 from northeast Atlantic (Portuguese) coast were used study age growth. The von Bertalanffy growth parameters for estimated through combination whole-otolith...
