Abstract Small-scale fisheries play a critical role in food security and contribute to nearly half of reported global fish catches. However, the status most small-scale stocks is still poor. In data-limited situations, length-based methods have been widely applied estimate reference points understand stock status. This study three different assessment (length-based indicators—LBI, spawning potential ratio—LBSPR, Bayesian biomass approach—LBB) predict sustainability Azores. Overall, showed...
Abstract Blackbelly rosefish Helicolenus dactylopterus (Delaroche, 1809) is one of the most important species demersal/deep‐water assemblages fished in NE Atlantic Ocean (Azores archipelago). However, there insufficient information about stock structure this to support analytical resource assessments and it currently managed with a precautionary approach. Here, we examine depth temporal distribution, size composition, sex, movement patterns blackbelly order test hypothesis that Azores region...
Laminaria digitata is a brown seaweed rich in prebiotic polysaccharides, mainly laminarin, but its alginate-rich cell wall could compromise nutrient access. Carbohydrases supplementation, such as individual alginate lyase and carbohydrases mixture (Rovabio® Excel AP), enhance digestibility potential. This study aimed to evaluate the effect of these enzymes on gut health weaned piglets fed with 10% L. digitata. Diets did not affect growth performance (P>0.05). The majority feed fractions had...
To obtain important baseline information about population dynamics and to provide valuable insights the possible effects of artisanal fishing on demersal fish community, this study had three specific objectives: (1) update annotated list teleost species occurring in Azores (mid-North Atlantic); (2) describe their depth distribution related fishery information; (3) evaluate annual changes observed abundance length composition. do this, a time series with 25 years scientific data from...
Abstract Blackspot sea bream (Pagellus bogaraveo) is the most important economical resource of Azorean fisheries. Juveniles (age 0 and 1) were detected along island coastlines in nursery grounds that sheltered individuals up to 13 cm (fork length). occurred coastal areas all seasons, but higher catch per unit efforts during summer. Larger tended be caught on shelves slopes islands seamounts by demersal, mixed hook, line exclusively found at inshore areas, while spawners distributed over...
Elasmobranchs are a vulnerable resource, more susceptible to overfishing than most teleosts, and their assessment is complicated due general lack of information about fisheries, biology ecology. This study aimed analyse all fishery survey data available for elasmobranchs caught over the past c. 25 years around Azores (NE Atlantic) provide baseline information, which can be used inform stock management strategies. Elasmobranch species covered pelagic, benthopelagic demersal habitats, from...
Given the scarcity of information suitable for stock assessments, growth and mortality seven exploited marine fishes in Azorean waters were estimated based on length-frequency data. The studied species Trachurus picturatus, Sparisoma cretense, Scomber colias, Scorpaena scrofa, Serranus atricauda, Seriola spp. Aphanopus carbo. parameters L∞ (cm), k (year-1) ϕ' through ELEFAN_GA_boot routine set at 55.87, 0.08 2.39 T. picturatus; 55.03, 0.11 2.53 S. cretense; 55.93, 0.18 2.76 colias; 61.11,...
This work describes and identifies the macroscopic corresponding microscopic changes of gonads an important commercial fish species, Helicolenus dactylopterus dactylopterus, from Azores Archipelago. The new contribution relates scale with histological stages. annual in gonad, together analysis monthly gonadosomatic indices, complementary observations scanning electron microscopy, allow us to conclude that females are internally inseminated between July November spawn January March. There is...
Studies on life history and stock structure of marine species have evolved in the Azores region during last 40 years. This information is essential to feed fishery assessment models that fit available data determine current status provide advice optimum (sustainable) exploitation. However, most these are only a fragmented manner several scientific papers, books, theses reports. In some cases, sources difficult access. The present document aims gather summarize biological, ecological...
Seamount fish communities are susceptible to variations due the oceanographic conditions and level of historical fishing effort. In NE Atlantic, Azores is considered an "oceanic seamount ecosystem area" because concentration high relative other regions. Scientific information on seamounts in remains scarce demersal fishery occurs mostly without any knowledge endorse sustainable harvest strategies. To make available important baseline dynamics populations inhabiting commercially exploited...
An analysis of size and reproduction Heterocarpus ensifer (Caridea: Pandalidae) off the Macaronesian archipelagos (Canary, Madeira, Azores islands, northeastern Atlantic) is done. The range samples was similar among studied, around |$9-39{\text{ mm}}$| carapace length (CL). length/wet weight relationship showed a negative allometry in males varied females. One-way regression slopes |$(b)$| pointed out significant differences all groups with exception males. Growth parameters indicated that...
Abstract The velvet belly lantern shark (Etmopterus spinax) forms a large component of the by-catch longline fishery off Azores, but is discarded due to lack commercial value. distribution and some biological aspects Etmopterus spinax were investigated from surveys between 1995 2005 Azores. highest catch rates at depths 500 650m (range 250–1200 m). overall sex ratio was 1:2.26 (M:F), with predominance females in all depth strata. total length range 17.5–48.0 cm for 18.5–45.0 males. This...
