Presence of atypical characteristics in two specimens of anglerfish Lophius budegassa Spinola, 1807, caught in the Bay of Biscay

Two specimens of anglerfish Lophius budegassa Spinola, 1807 with atypical characteristics, caught in the Bay of Biscay by trawlers during 1996 and 1997, are described. One of them was totally albinistic, with unpigmented peritoneum, blindness, and 5 rays at its first dorsal fin. The first three characteristics seem to be associated, and it is the largest albinistic specimen of L. budegassa described to date. The other specimen had orange spots on its dorsal side and on the edges of the pectoral fins on the ventral side.Se describen las características atípicas de dos ejemplares de rape Lophius budegassa Spinola, 1807, capturados por barcos de arrastre en el mar Cantábrico en los años 1996 y 1997. Uno de ellos presentaba albinismo total, peritoneo despigmentado, ceguera total y 5 radios en su primera aleta dorsal. Los tres primeros caracteres, al parecer, se encuentran asociados y se trata, además, del ejemplar albino de L. budegassa de mayor talla descrito hasta la actualidad. El otro ejemplar presentaba manchas naranjas en su parte dorsal y en los extremos de la parte ventral de sus aletas pectorales.Instituto Español de Oceanografí

Age determination procedures for benthic fish in Spanish Institute of Oceanography (IEO)

This handbook presents a summary of the age estimation procedures used in the Spanish Institute of Oceanography (IEO) for some of the main commercial benthic species of fish for the Spanish fleet: megrim (Lepidorhombus whiffiagonis), four spot megrim (Lepidorhombus boscii), white anglerfish (Lophius piscatorius), black anglerfish (Lophius budegassa). It provides information about the sampling program, the morphology of hard parts (otoliths and illicia), their extraction, preparation, and the age estimation criteria. A summary of information related to the accuracy, validation and corroboration of age of each species is also presented, as well as that related to the precision, quality control and verification of age

Age determination procedures on small and medium pelagic species in Spanish Institute of Oceanography (IEO)

This handbook presents a summary of the age estimation procedures used in Spanish Institute of Oceanography (IEO) for some of the main commercial small and medium pelagic species of the Spanish fleet: anchovy (Engraulis encrasicolus), sardine (Sardina pichardus), mackerel (Scomber scombrus), chuck mackerel (Scomber colias), horse mackerel (Trachurus trachurus), Mediterranean horse mackerel (Trachurus mediterraneus) and blue whiting (Micromesistius poutassou). It provides information about the sampling program, otolith extraction and preparation, and the age estimation criteria. A summary of the information related to the age accuracy, validation and corroboration of each species is also presented, as well as that related to the age precision, quality control and verification

Anales del III Congreso Internacional de Vivienda y Ciudad "Debate en torno a la nueva agenda urbana"

Acta de congresoEl III Congreso Internacional de Vivienda y Ciudad “Debates en torno a la NUEVa Agenda Urbana”, ha sido una apuesta de alto compromiso por acercar los debates centrales y urgentes que tensionan el pleno ejercicio del derecho a la ciudad. Para ello las instituciones organizadoras (INVIHAB –Instituto de Investigación de Vivienda y Hábitat y MGyDH-Maestría en Gestión y Desarrollo Habitacional-1), hemos convidado un espacio que se concretó con potencia en un debate transdisciplinario. Convocó a intelectuales de prestigio internacional, investigadores, académicos y gestores estatales, y en una metodología de innovación articuló las voces académicas con las de las organizaciones sociales y/o barriales en el Foro de las Organizaciones Sociales que tuvo su espacio propio para dar voz a quienes están trabajando en los desafíos para garantizar los derechos a la vivienda y los bienes urbanos en nuestras ciudades del Siglo XXI
