“…The species is not thought to migrate extensively (Collette and Nauen, 1983), with one report (Batista and Fabrè, 2001) suggesting that carite migration in Trinidadian waters covers about 70 nautical miles (∼130 km). Sturm (1974) observed peak spawning between October and April in low salinity waters in the Gulf of Paria off the southwest coast of Trinidad and hypothesized occurrence of a post-spawning, 'clockwise' feeding migration northward to higher salinity waters off the north coast.…”

“…The Spanish mackerel (Scomberomorus brasiliensis, Scombridae) (Collette et al, 1978) is a neritic tuna (Fonteles Filho, 1989) distributed from Belize to south Brazil (Carvalho-Filho, 1999) of high commercial interest in Trinidad and Tobago and Venezuela (Hodgkinson-Clarke, 1990), and in Brazil, especially in the state of Maranhão (Fonteles-Filho, 1988). Few studies have been conducted in this species (Batista and da Fabré, 2001;Maia et al, 2015), and only one aimed at evaluating its genetic structure (Gold et al, 2010). This work describes how the identification and validation of a large number of SNPs is achievable combining ddRAD and long read high throughput sequencing (e.g.…”

A combination of a RADseq method (ddRAD) with long read high throughput sequencing (Roche 454) was tuned up in order to identify and validate a set of SNPs useful for gene diversity analysis in two important South American commercial tuna (Thunnus albacares and Scomberomorus brasiliensis). A total of 11 and 21 individuals of T. albacares and S. brasiliensis, respectively, were used for SNP identification. DNA was individually digested with two restriction enzymes (SbfI and SphI) and fragments between 300 and 600 bp selected. Combinatorial barcoding was used to identify individuals by including short sequences (5-7 bp) in the adaptors of each restriction site (P1 and P2). After adaptor ligation, samples were pooled and size-selected, amplified by PCR, and sequenced on a 454 GS-Junior sequencer. A total of 180,779 reads were produced with an average length and coverage of 287 bp and 26x, respectively. Sets of 60 and 79 SNPs were in silico selected for T. albacares and S. brasiliensis, respectively, and were tested and validated in 74 and 66 individuals, respectively, on a MassARRAY platform. A total of 36 and 47 SNPs were polymorphic and useful for population analysis. A preliminary study on two distant Brazilian populations of both species (∼3000 km) with these SNPs suggested the absence of significant structure among local populations of both species. Our results demonstrate the possibility of combining ddRAD with long read high throughput sequencing for marker development in species with scarce genomic resources.

“…Small-scale fisheries have their traditional grounds, in accordance to the specific periods of aggregations and migrations of fish stocks. For example, in the Brazilian northeast, summers (dry season) are the period to catch groupers and snappers at the continental shelf edge [24], whereas the serra Spanish mackerel is caught in the rainy months all over the northern coast of South America [25]. …”

BackgroundAcquiring fast and accurate information on ecological patterns of fishery resources is a basic first step for their management. However, some countries may lack the technical and/or the financial means to undergo traditional scientific samplings to get such information; therefore affordable and reliable alternatives need to be sought.MethodsWe compared two different approaches to identify occurrence patterns and catch for three main fish species caught with bottom-set gillnets used by artisanal fishers from northeast Brazil: (1) scientific on-board record data of small-scale fleet (n = 72 trips), and (2) interviews with small-scale fishers on Local Ecological Knowledge (LEK) (n = 32 interviews). We correlated (Pearson correlations) the months cited by fishers (LEK) as belonging to the rainy or to the dry season with observed periods of higher and lower precipitation (SK). The presence of the three main fish species at different depths was compared between LEK and SK by Spearman correlations. Spearman correlations were also used to compare the depths of greatest abundance (with the highest Capture per Unit Effort - CPUE) of these species; the CPUEs were descendly ordered.ResultsBoth methods provided similar and complementary bathymetric patterns of species occurrence and catch. The largest catches occured in deeper areas, which also happened to be less intensively fished. The preference for fishing in shallower and less productive areas was mostly due to environmental factors, such as weaker currents and less drifting algae at such depths.ConclusionBoth on-board and interview methods were accurate and brought complementary information, even though fishers provided faster data when compared to scientific on-board observations. When time and funding are not limited, integrative approaches such as the one presented here are likely the best option to obtain information, otherwise fishers’ LEK could be a better choice for when a compromise between speed, reliability and cost needs to be reached.Electronic supplementary materialThe online version of this article (doi:10.1186/s13002-017-0156-9) contains supplementary material, which is available to authorized users.
