All demersal fish with planktonic larvae settle at some point early in life, generally around the transformation from to juveniles or soon after. Sampling pre-settlement very young, settled is challenging due spatial concretions within habitat and pulsed, rapid nature of settlement process. There a lack robust methods that enable this sampling, but information on settlement, represents mortality bottleneck, crucial for follow-up populations fisheries conservation purposes. An empirical...

Abstract We studied the otolith microstructure and growth of sardine, Sardina pilchardus , in North Aegean Sea (eastern Mediterranean Sea), using samples larvae juveniles that had hatched winter (November–January) winter–spring (February–May), respectively. The developed during an extended period coinciding with marked pelagic ecosystem changes (from winter, mixed conditions to summer, stratified waters). To examine relationship between environmental observed variability their...

The Alborán Sea is a hydrographically complex and variable area in which wind-driven coastal upwelling occurs. Its most abundant small pelagic resource the sardine (Sardina pilchardus), subject to major interannual oscillations. Postflexion stages of larvae were sampled their main nursery grounds north Sea, juveniles periodically throughout recruitment season. Daily growth analysis was used identify periods favourable for larval survival assess evolution daily increment widths during first...

Purpose The purpose of this paper is to provide a profile fresh fish consumers and analyze trends in their choices fish. In addition, study investigates whether being an active practitioner angling or belonging household with activity has effect on consumers' choices. Design/methodology/approach Consumers' habits, profiles, perceptions were obtained from randomized personal interviews ( n =395) at traditional markets (the main source for Spaniards) restaurant managers =11) carried out...

Temperature is often an important variable influencing the vertical position of fish larvae in water column. The same species may show different distributions areas with a strong near-surface seasonal thermocline compared to isothermal regions. In surface thermocline, tuna significant preference for warmer layers. Little known regarding larval distribution waters and on associated assemblages. We conducted stratified sampling using methodology fishing device (MOCNESS) two major spawning...

The first weeks in life are crucial for the fate of fish. During this period, fish show large dispersal rates and suffer from massive mortality due mainly to predation. Intrinsic extrinsic processes (growth rates, advection, behavior, diseases) affect have profound consequences on populations. For a century now, describing distribution, physiology dynamics early phases has been focus intense research, building solid community scientists that met at 43rd Annual Larval Fish Conference, held...

Abstract. Early-life stages play a key role in the dynamics of bipartite life cycle marine fish populations. Difficult to monitor, observations these are often scattered space and time. While Mediterranean coastlines have been surveyed, no effort has made assemble historical observations. Here we build an exhaustive compilation dispersal traits for coastal species, considering situ growth models (Di Stefano et al., 2023; https://doi.org/10.17882/91148). Our database contains over 110 000...

During the summer, relative influence of resident Atlantic Waters (AW) and new AW largely drives mesoscale dynamics around Balearic Islands (NW Mediterranean). Two principal summer hydrographic scenarios were identified in region, differentiated by position density front between within archipelago its associated activity. In this study, we investigated how those early larval fish assemblages, analyzing data from two cruises representative these (2004 2005). Redundancy analysis was used to...

The European anchovy fishery in the Gulf of Cádiz (ICES Division IXa South) is largely influenced by age-0 individuals. Knowledge young year growth dynamics crucial for management, yet data on daily are lacking area. Linking patterns to environment requires information habitat occupancy through ontogeny fish that reach fishery, as use different areas and Guadalquivir Estuary development. We describe otolith microstructure analysis, couple these with microchemical signals otoliths shed light...

We analyzed the influence of stratification process in vertical distribution larval fish a microtidal coastal Mediterranean zone. By applying Self Organizing Maps (SOM) technique, we could analyze complex dataset accounting for non-linear processes. The analysis integrated multivariate data on and environmental parameters two depth strata through two-time components (nictimeral fortnightly main spawning seasons), considered size-based information. Although causal relationships cannot be...

The age and growth patterns of the mesopelagic fish Ceratoscopelus maderensis (family Myctophidae) western Mediterranean Sea were described throughout its entire life cycle (from larvae to adult stages) using sagittae otoliths 59 individuals collected in December 2009. Three characteristic zones identified along cross-section (larval, metamorphic juvenile-adult zones). Assuming rings as daily increments, analysed 3.5 64 mm standard length [SL]) would range from 7 332 days. relationship...
