Zonal travel cost approaches to assess recreational wild mushroom picking value: Trade-offs between online and onsite data collection strategies
(Forest Policy and Economics, 2019-03-04)
Mushroom picking is a growing recreational activity in Europe. Since the institutional environment moves towards regulating mycological resources, estimating the value of this ecosystem service becomes a key tool ...
Colorimetric DNA-based assay for the specific detection and quantification of Ostreopsis cf. ovata and Ostreopsis cf. siamensis in the marine environment
(Harmful Algae, 2019-03-16)
Ostreopsis is a toxic benthic dinoflagellate largely distributed worldwide in tropical and temperate areas. In the Mediterranean Sea, periodic summer blooms have been reported and have become a serious concern due to their ...
Gamete quality and management for in vitro fertilisation in meagre (Argyrosomus regius)
(Aquaculture, 2019-05-14)
The aquaculture of meagre (Argyrosomus regius) requires methods for the control of reproduction that enable the production of families from specific individuals for selective breeding programs. We experimentally determined ...
Contrasting outcomes of Vibrio harveyi pathogenicity in gilthead seabream, Sparus aurata and European seabass, Dicentrachus labrax
(Aquaculture, 2019-06-11)
Vibrio harveyi has been reported as the dominant heterotrophic bacterial species in western Mediterranean coastal areas during warm seasons, and is recognized as an economically significant pathogen for the aquaculture ...
Agricultural soil organic carbon stocks in the north-eastern Iberian Peninsula: Drivers and spatial variability
(Science of the Total Environment, 2019-02-22)
Estimating soil organic carbon (SOC) stocks under agriculture, assessing the importance of their drivers and understanding the spatial distribution of SOC stocks are crucial to predicting possible future SOC stocks scenarios ...
Optimal stocking density for beluga, Huso huso, and ship sturgeon, Acipenser nudiventris during the grow‐out phase
(Journal of Applied Ichthyology, 2018-10-18)
The influence of three different initial stocking densities (SD) in flowthrough systems was evaluated on growth performance and feed utilizaition in beluga, Huso huso, and ship sturgeon, Acipenser nudiventris, juveniles ...
Weaning European glass eels (Anguilla anguilla) with plant protein-based diets and its effects on intestinal maturation
(Comparative Biochemistry and Physiology Part A: Molecular & Integrative Physiology, 2018-11-09)
Weaning glass eels with compound diets (36% proteins, 16% lipids) differing in their fishmeal (FM) level (50, 75 and 100% FM replaced by a blend of plant proteins, PP) was compared to a group fed cod roe. Weaning lasted ...
The effect of algal turbidity on larval performance and the ontogeny of digestive enzymes in the grey mullet (Mugil cephalus)
(Comparative Biochemistry and Physiology Part A: Molecular & Integrative Physiology, 2018-11-12)
A study comprised of two trials determined the effects of water turbidity produced by live microalgae and inert clay particles on the larval rearing of grey mullet (Mugil cephalus). Trial 1 evaluated the effect of microalgae ...
Price transmission dynamics for quality‐certified food products: A comparison between conventional and organic fluid milk in Italy
(Agribusiness, 2018-06-25)
Despite the vast number of works investigating price transmission (PT) processes in diverse agrifood markets, very little has been said about quality‐differentiated products. In this paper, we compare the conventional and ...
Reproductive success of a marine teleost was correlated with proactive and reactive stress‐coping styles
(Journal of Fish Biology, 2019-01-23)
The present study investigated the relationship between reproductive success and stress‐coping styles in gilthead seabream Sparus aurata in captivity. To characterise stress‐coping styles, a total of 22 breeders were ...
