Previously only five species had been documented in El Salvador: Chaetopleura lurida (Sowerby, 1832); Ischnochiton guatemalensis (Thiele, 1910); Ceratozona angusta (Thiele, 1909); Chiton stokesii (Broderip, 1832) and Acantochitona exquisita (Pilsbry, 1893). Of these, L. guatemalensis and A. exquisita were not collected in this census. Seven other species are reported here for El Salvador for the first time: Lepidochitona beanii (Carpenter, 1857); Ischnochiton dispar (Sowerby, 1832); Stenoplax limaciformis (Sowerby, 1832); Callistochiton expressus (Carpenter, 1865); Acanthochitona arragonites (Carpenter, 1867); A. ferreirai (Lyons, 1988) and A. hirudiniformis (Sowerby, 1832). The known geographic distribution of 1. dispar is extended to the north. An un-named species of Lepidochitona is briefly described.

The results were obtained from field surveys (between the years 2000 and 2004), the scarce literature sources, and Internet information. A total of 37 species and six genera are reported. The most abundant echinoderms in rocky shores were: Phataria unifascialis, Echinometra vanbrunti, Holothuria kefersteini, as well as Astropecten armatus in soft bottoms.

La coordinación entre autoridades pertinentes e implementación de protocolos nuevos, así como reglamentos son importantes para prevenir daños a los ecosistemas acuáticos involucrados.Realidad y Reflexión Año 18, No 47, 48 Enero-Junio 2018; pp.13-20

Los censos se hicieron principalmente en el área denominada Cerros Quemados, donde se establecieron dos transeptos de 50 m de longitud por dos de ancho aproximadamente, a 4-5 y 8-9 m de profundidad, en los que se registró la cantidad de especies observadas a ambos lados. Los resultados indicaron la dominancia numérica de Amatilania nigrofasciata, otras especies con mucha menor abundancia fueron: Astatheros macracanthus, Cichlasoma trimaculatum, Parachromis managuensis. Se considera que la metodología utilizada permitió la observación de especies asociadas a fondos rocosos durante el día; sin embargo, existen otros hábitats como vegetación sumergida (Hydrilla verticillata), flotante y fondos blandos que no se exploraron.

National health authorities usually measured toxin levels in Ostrea iridescens, however other species were analyzed during this microalgae bloom: Anadara similis, Anadara tuberculosa and Modiolus sp. El Salvador authorities consider 400 mouse units/100 g the highest value that is safe for human health. During this period toxin levels in 0. iridescens and Modiolus sp. increased from values under 400 to 3977 and 15,468 mouse units/100 g, respectively. Persistent and higher levels were recorded in oyster and mussel banks on the west part of the country. The Ministry of Health and Social Assistance treated 41 slight to moderate intoxications associated to bivalve mollusks consumption.
