Spatial distribution and abundance of the giant tiger prawn, Penaeus monodon (Fabricius, 1798), in the Gulf of Urabá (Caribbean), Colombia, South America

Abstract

This is the first systematic assessment conducted on fouling communities to determine the current status of six non-native marine invertebrates that were first recorded in Hong Kong three decades ago. They include the solitary ascidian, Ciona intestinalis; the slipper limpet, Crepidula onyx; the bryozoan, Bugula californica; the Caribbean bivalve, Mytilopsis sallei; the Mediterranean mussel, Mytilus galloprovincialis; and the boring isopod, Sphaeroma walkeri. Field surveys were conducted at 31 locations during wet (2011) and dry (2012) seasons and included fouling communities on piers and mariculture zones from estuarine to oceanic zones. The sampling was conducted by using photo-quadrats, destructive quadrats and field observations. To detect temporal changes in the abundance and recruitment of the sedentary non-native species, three piers were monitored with permanent photo-quadrats and recruitment panels for a one year period. We examined the relationship between seawater quality data available for Hong Kong and the abundances of fouling and non-native species. Only four of the six target non-native species were recorded in this survey. The isopod Sphaeroma walkeri was common and widely distributed in fouling communities in Hong Kong, while Ciona intestinalis, Crepidula onyx, and Mytilopsis sallei were uncommon and mainly restricted to areas with intensive human activities and poor seawater quality. These findings suggest that near shore human activities and poor water quality could increase the risk of establishment of non-native species in Hong Kong's marine fouling communities.

Cambios globales en los manglares del golfo de Urabá (Colombia): entre la cambiante línea costera y la frontera agropecuaria en expansión

“…Finalmente, aunque en el golfo de Urabá se han identificado otras amenazas asociadas con cambios globales tales como enfermedades de los mangles (agallas inducidas por bacterias y debilitamiento de raíces por moluscos barrenadores: Sánchez-Alférez et al 2009) e invasiones de especies marinas (v.g., camarón tigre: Penaeus monodon; Sandoval et al 2014), no han sido objeto de estudio por parte de mi grupo y los estudios disponibles no permiten hacer evaluación de impacto a nivel ecosistémico y, por lo tanto, estimación de la vulnerabilidad.…”

Potential distribution of the tiger shrimp Penaeus monodon (Decapoda: Penaeidae), an invasive species in the Atlantic Ocean

“…In addition to competing for space and food with other species, the economic impact that could be caused by the invasion of P. monodon in the Atlantic varies according to the region. In Colombia, for example, it could threaten the Southern withe shrimp (Litopenaeus schmitti) (Sandoval et al, 2014), while in Venezuela the fisheries of five shrimp species could be affected: white shrimp L. schmitti, brown shrimp Farfantepenaeus subtilis, pink spotted shrimp F. brasiliensis, pink shrimp F. notialis, and titi shrimp Xiphopenaeus kroyeri (Aguado & Sayegh, 2007). If invasions occur in Mexico, populations of brown shrimp F. aztecus, pink shrimp F. duorarum, white shrimp L. setiferus, pink shrimp F. brasiliensis, and rock shrimp Sicyonia brevirostris (Morán-Silva et al, 2017) could all be threatened.…”

Presencia del camarón tigre gigante <i>Penaeus monodon</i> (Decapoda: Penaeidae) en las costas del Atlántico Americano. Revisión

“…Al observar los registros históricos de P. monodon (Coelho et al 2001, Santos & Coelho 2002, Silva et al 2002, Tavares & Braga 2004, Medellín et al 2011, Aniceto et al 2014, Sandoval et al 2014, Morais et al 2015, Zink et al 2018) (Tablas 1 y 2) se puede indicar que hay más de una década entre la fuga y las primeras capturas de esta especie por pescadores ribereños y de altamar en el medio silvestre del Atlántico. A partir del 2000, se hizo frecuente la captura ocasional de esta especie de camarón en países como Brasil, Colombia, Costa Rica, Cuba, EUA, Guatemala, México y Venezuela (Tabla 2, Fig.…”
