“…Fleets in the Saudi artisanal fisheries are composed of two craft types, tarad and dhow (Abdulqader et al, 2017;Roa-Ureta, 2015a). Tarad are smaller (<10 m length) and faster (>30 knots) boats operating on single-day fishing trips.…”

In this study we lay the groundwork for sustainability‐oriented fisheries management, by estimating parameters the life history of orange‐spotted trevally Carangoides bajad as well as trends of abundance in coral‐reef habitats. We observed a new record of maximum size of 720 mm fork length. Carangoides bajad is a moderately long‐lived (14 years) and slow‐growing (K = 0.085 year−1) carangid species, closer to a K‐selection species, with higher vulnerability to fishing and lower rates of recovery when the population level is low. Growth and biological composition in terms of length and age categories do not differ between the sexes, but females become mature faster. Reproductively active months (May–August) overlapped with those from Emirati waters further south. The abundance index showed a pronounced drop during 1990–1993, possibly in connection with habitat deterioration during the Gulf War (1990–1991) oil spill. The index increased gradually from 1994 and has fluctuated close to the reference level of 1985 up to the present. Considering the findings of large‐sized and old‐age individuals and abundance index from coral reefs close to its level three decades back, the C. bajad stock in the western part of The Gulf appears to be in healthy exploitation status despite growing harvesting rates.

“…Spanish mackerel (Scomberomorous niphonius), belonging to family Scombridae (Percida), is the most commercially important pelagic species in the northern Persian Gulf [1,2]. Besides, Spanish mackerel is one of the most important aquaculture species in China, especially in east and southeast China [3].…”

Exploring the spoilage mechanism of Spanish mackerel is important to reduce the waste of Spanish mackerel and extend its shelf life. Cold chain logistics are commonly used to maintain the high quality and prolong the shelf life of aquatic products in circulation and storage. We assessed the sensory (body surface, odor, fish gills, fish elasticity, eyes, and overall assessment), chemical (total volatile base nitrogen (TVB-N), pH and 2-thiobarbituric acid (TBA)), and microbial characteristics (total viable counts (TVCs) and lactic acid bacteria) of Spanish mackerel combined with high-throughput sequencing at frequent intervals to determine their freshness and specific spoilage organisms (SSOs) during 0 °C cold chain logistics. Results showed that TVB-N, TBA, and TVCs correlated well (R2 > 0.90) with the sensory scores with prolonged circulation and storage time. The SSOs of Spanish mackerel were Proteobacteria in phylum and Pseudomonas in genus. The shelf life of mackerel under the 0 °C ice-stored cold chain system was approximately seven days, which is roughly three days longer compared with the traditional low-temperature storage method. These findings indicated that the freshness evaluation of Spanish mackerel in cold-chain circulation could be achieved by selecting appropriate chemical, microbial, and sensory indices. The study contributes to extend the shelf life of cold-chain Spanish mackerel by inhibiting the growth of dominant bacteria and provides a basis for the development of methods and tools to predict the shelf life of Spanish mackerel.

“…Using methodologies amenable to exploiting datalimited situations, such as the MAGD model developed by Roa-Ureta (2012, 2014, may help produce a more complete picture of the exploitation of marine resources in the Mediterranean, moving beyond the picture derived from standard VPA-type assessments applied recurrently to a handful of important commercial species (e.g. those given in Cardinale et al 2010, 2011 andsimilar reposts).…”

“…These high-frequency data, when collected over several years and combined with limited additional information on the biology of target species, can be used for stock assessment purposes using depletion models. In multi-annual generalized depletion (MAGD) models (Roa-Ureta 2012, 2014, the classical assumptions of depletion of a closed population subject to direct proportionality between catch per unit effort (CPUE) and abundance (Brodziak andRosenberg 1993, McAllister et al 2004) are relaxed. When running at a monthly scale, the regular annual pulses in abundance produced by the recruitment of a new cohort to the fishery can be used in MAGD models as prior information to the timing and magnitude of recurrent perturbations.…”

Summary:A multi-annual generalized depletion model was applied to a coastal fishery in Vilanova i la Geltrú (western Mediterranean) to assess the exploitation status of striped red mullet (Mullus surmuletus) and cuttlefish (Sepia officinalis), two of the main target species of Mediterranean small-scale fisheries. It is shown that in data-limited stocks, which is often the case in small-scale fisheries, catch and effort data at high temporal frequency (day, week, month) complemented with biological information and a priori knowledge (mean body weight, natural mortality and period of recruitment to the fishery) can be effectively exploited to produce assessment results applicable to fisheries management. For the two species analysed, the assessment results showed that exploitation rates are high and vulnerable biomass has been decreasing over the last 14 years.Keywords: stock assessment; data-limited; depletion model; small-scale fisheries; Mullus surmuletus; Sepia officinalis.Aplicación de un modelo multi-anual generalizado de depleción para la evaluación de una pesquería costera con limitación de datos en el Mediterráneo occidental Resumen: Se utilizó un modelo multi-anual generalizado de depleción para evaluar el estado de explotación del salmonete de roca (Mullus surmuletus) y la sepia (Sepia officinalis) capturados por la flota costera de Vilanova i la Geltrú (Mediterráneo occidental). Estas especies representan dos de las principales especies objetivo de las pesquerías mediterráneas artesanales. El análisis muestra que para stocks pesqueros con información limitada, los datos de captura y esfuerzo a alta frecuencia temporal (diaria, semanal o mensual), junto a información biológica y conocimiento a priori (peso corporal medio, mortalidad natural, periodo de reclutamiento), pueden ser utilizados de manera efectiva para producir resultados de evaluación aplicables a la gestión de pesquerías. En las dos especies analizadas, los resultados de la evaluación muestran que las tasas de explotación son elevadas y que la biomasa vulnerable ha disminuido de manera continua en los últimos 14 años.
