A través de esta nueva serie tratamos de conocer diferentes aspectos personales de los integrantes de la comunidad ictiológica iberoamericana. Esta iniciativa, comparte el espíritu y objetivo de las semblanzas nacionales buscando informalmente, otro punto de unión en la “comunidad de ictiólogos iberoamericanos”. Quizás esté equivocado en mi apreciación, pero creo que vale la pena este intento, ya que, con la colaboración generosa e insoslayable de los integrantes de este “universo”, señalaremos un registro en el tiempo de la Ictiología Neotropical.

The absolute fecundity of Saurida tumbil ranged between 24160 to 172000 eggs with weight range of 230-670 g. Linear relationship between fecundity and weight was more valid than that of length and ovary weight. The fish breed once a year during November to March. The length at which 50% of the females mature was calculated as 296 mm. The female dominated the commercial catch and overall male to female ratio of population was 1:1.62 throughout the year.

The present investigation suggests that Saurida tumbil (Bloch, 1795) is carnivorous and predacious feeding mainly on fishes followed by crustaceans and molluscs. Cannibalism has been observed in the species. Young ones of this species were observed to feed on small fish and Acetes spp., while adults feed on a variety of food. However, fish seems to be the preferred food item. Monthly gastro-somatic index in males indicates poor feeding in the month of february and maximum during august and september. In females, monthly gastro-somatic index indicate poor feeding in december and maximum during january and march. Sex wise study of feeding intensity did not reveal significant difference in males and females.

In 1966 the artist Antonio Lopez was rejected for the chair in “Preparatorio de colorido” (Preparatory Colouring) by the San Fernando School of Fine Arts where he himself presented his work Nevera de hielo (Ice Box). After 5 years as a “stand in” for this post he left the Institution. This article analyzes the circumstances and proof of a decade where there appears to be evidence of a definite change in his work, more toward Realism, uncomfortable in a system that maintained with difficulty the traditional academic model copy, and incompatible with, in those years was imposed by Spain. At the same time his relation with photography conditioned by the theoretical thoughts of the artist, and his work methods also are analyzed in this article.

In 1990, Juan Antonio Ramírez made known his iconological paranoiac method to the academic world. It is a system devised to study Dalí´s work, born of happy matrimony between the catalonian artist´s critical paranoiac method and the first iconographic school of Warburg and Panofsky. What, at first sight, seemed to be an extravagant methodology with little academic credibility, turned out to be, by going forward in time, an effective research method when analyzing Dali´s initial works. It is no wonder that, at the beginning of XXI century, this hybridization between Dalí´s and Panofsky’s methods, were regarded as a strange and nonsensical idea. Nevertheless, twenty years after, blatant examples have been noted, which endorse the advantages of this new system for “iconographic” study. As usual, this new contribution by Juan Antonio Ramirez to art history methodology is called upon to have a successful future survival, in forthcoming generations. This article, attempts to analyze this method, inquiring into the validity, effectiveness and practical utility.
