It. Paleontol. Strat., 124(3): 535-571. Keywords: Sciaenidae; new genera and species; Neogene; Tarkhanian; North Caucasus; Sarmatian; Croatia; Paratethys. Abstract. The fossil record of sciaenid fishes (based on both otoliths and osteological finds) from the Neoge- ne of the Paratethys is reviewed. The species Labrax (=Morone) multipinnatus Gorjanović-Kramberger, 1882 from the Sarmatian of Croatia (Sv. Nedelja) that was originally described as a sea bass of the family Moronidae is re-assigned to the extant croaker genus Argyrosomus. Two new genera and species of sciaenid fishes are described based on a single skeleton each, namely Landinisciaena popovi gen. et sp. nov. from the Tarkhanian (Lower/Middle Miocene) North Shir- vanskaya Formation exposed along the Pshekha River, North Caucasus, Russia, and Croatosciaena krambergeri gen. et sp. nov. from the Sarmatian s.s. (Middle Miocene) deposits of Dolje in the nearby of the city of Zagreb, Croatia. The holotype of the former taxon possesses a well-preserved saccular otolith in situ (first record of in situ croaker otolith in Europe) similar to the otoliths of the extant genus Atractoscion. The otolith-based Ottnangian species Atractoscion elongatissimus Schwarzhans, 1993 is transferred to the genus Landinisciaena gen. nov. A comprehensive revision of the Neogene otholith-based sciaenid record from Paratethys resulted in the recognition of three new genera (Chaoia gen. nov., Pontosciaena gen. nov. and Leptosciaena gen. nov.) as well as in the description of a new species L. caputoi sp. nov. from the uppermost Messinian (Lago-mare phase) of Italy. A number of known otholith-based species were either synonymized or assigned to a new generic affiliation. The complex biogeographic history of the Neogene Paratethyan sciaenids (based on both otoliths and skeletal records) is discussed, resulting in the recognition of a vanished “sciaenid bioprovince”.

An updated checklist and characterisation of the ichthyofauna (Elasmobranchii and Actinopterygii) of the Laguna de Tamiahua, Veracruz, Mexico. Acta Ichthyol. Piscat. 48 (4): 341–362. Background. Laguna de Tamiahua is ecologically and economically important as a nursery area that favours the recruitment of species that sustain traditional fisheries. It has been studied previously, though not throughout its whole area, and considering the variety of habitats that sustain these fisheries, as well as an increase in population growth that impacts the system. The objectives of this study were to present an updated list of fish species, data on special status, new records, commercial importance, dominance, density, ecotic position, and the spatial and temporal distribution of species in the lagoon, together with a comparison of Tamiahua with 14 other Gulf of Mexico lagoons. Materials and methods. Fish were collected in August and December 1996 with a Renfro beam net and an otter trawl from different habitats throughout the lagoon. The species were identified, classified in relation to special status, new records, commercial importance, density, dominance, ecotic position, and spatial distribution patterns.

Biota Neotropica. 19(1): e20170432. http://dx.doi.org/10.1590/1676-0611-BN-2017-0432 Abstract: Demersal fishery resources are abundant on continental shelves, on the tropical and subtropical coasts, making up a significant part of the marine environment. Marine demersal fishery resources are captured by various fishing methods, often unsustainably, which has led to the depletion of their stocks. In order to inventory the marine demersal ichthyofauna on the Southern Brazilian coast, as well as their conservation status and distribution, this study analyzed the composition and frequency of occurrence of fish captured by pair trawling in 117 fishery fleet landings based in the State of São Paulo between 2005 and 2012.

  • A Baseline Investigation Into the Population Structure of White Seabass, Atractoscion Nobilis, in California and Mexican Waters Using Microsatellite DNA Analysis
    Bull. Southern California Acad. Sci. 115(2), 2016, pp. 126–135 E Southern California Academy of Sciences, 2016 A Baseline Investigation into the Population Structure of White Seabass, Atractoscion nobilis, in California and Mexican Waters Using Microsatellite DNA Analysis Michael P. Franklin, Chris L. Chabot, and Larry G. Allen* California State University, Northridge, Department of Biology, 18111 Nordhoff St., Northridge, CA, 91330 Abstract.—The white seabass, Atractoscion nobilis, is a commercially important member of the Sciaenidae that has experienced historic exploitation by fisheries off the coast of southern California. For the present study, we sought to determine the levels of population connectivity among localities distributed throughout the species’ range using nuclear microsatellite markers. Data from the present study have revealed distinct genetic breaks between the Southern California Bight, Pacific Baja California, and the Peninsula of Baja California. The white seabass, Atractoscion nobilis, is the largest species of croaker (Sciaenidae) occur- ring off the coast of southern California (Miller and Lea 1972) and has been highly prized his- torically by commercial and recreational fisheries. Declines in catches of white seabass have occurred historically to the point that population numbers had dropped to critically low levels (Pondella and Allen 2008). These declines have been followed by increases in commercial catches due to management strategies such as the prohibition of gill-nets along the southern California coast (Allen et al. 2007; Pondella and Allen 2008). Despite the economic importance of the white seabass and its history of over-exploitation and rebound, information on population structure life history has been limited. What is known of the life history of the white seabass is that the species is a broadcast spaw- ner, with males fertilizing eggs that females release into the water column.
