| The aim of the present study was to evaluate marine contamination and toxicity in sediment and pore water from the areas of Izmir Bay (Turkey) and Mytilene Harbor (Greece). The evaluation was performed in terms of selected toxic-metals, polycyclic aromatic compounds (PAR) and toxicity to sea urchin (Paracentrotus lividus) early development and fertilization. Significantly higher levels of metals and total PAR were detected in Izmir vs. Mytilene sediment, and the highest contamination was detected in Izmir Bay innermost sites. Bioassays were carried out in P. lividus embryos and sperm, by evaluating developmental defects and changes in fertilization success by exposing sea urchin embryos or sperm to sediment/seawater suspensions. Whole sediment (WS) showed... |

| Se evaluó la efectividad de los erizos de mar Echinometra lucunter y Lytechinus variegatus como controladores biológicos del “fouling” en un cultivo piloto del pectínido Nodipecten nodosus en la bahía de Nenguange, Santa Marta, Caribe colombiano; para lo cual se utilizaron animales con tallas promedio de 50 y 55 mm respectivamente. Fueron establecidos cinco tratamientos: 1) y 2) Dos y cuatro individuos de E. lucunter por piso de mini-linterna; 3) y 4) Dos y cuatro individuos de L. variegatus por piso de mini-linterna y 5) Control sin erizos. Los pectínidos utilizados fueron obtenidos del medio natural mediante colectores artificiales instalados en la estación de cultivo, con una talla promedio de 80 mm. Los resultados mostraron que la densidad de 4... |
