new approach to the classification of algae

A new classification of algae up to the ordinal level, based on five kingdoms of living organisms, has been suggested in this paper, wherein algae are distributed in this paper, wherein algae are distributed in three kingdoms and include 19 phyla, 31 classes and 107 orders. Delineation of these groups is based on the micromorphological, ultrastructural and phycochemical characteristics of algae. As a result, three new phyla i.e. Volvocophyta, Porphyridiophyta and Vaucheriophyta, ten new classes i.e. Chrooco-phyceae, Porphyridiophyceae, Siphonocladophyceae, Vaucheriphyceae, Dictyophyceae, Nemaliophyceae and Ceramiophystales, Pelagomonadales, Vischeriales and Vacuolariales have been created. Typified names are preferred to descriptive names of various taxa. A comparison has also been made between various phyla regarding their diagnostic characters

Ichthyophthirius multifilis protozoa in gasteropelecus sternicola, Linnaeus 1758, collected in the area of Belém state of Pará Brazil

The present study describes for the first time Ichthyophthirius multifilis infecting twenty ornamental fishes Gasteropelecus sternicola (white butterfly fish). Parasites were found in 100 percent of examined fishes. Light microscopy and scanning electron microscopy (SEM) were used in this exam. SEM showed fins destroyed by the parasites action. High prevalence of the parasitism has a high concern as those fishes are of commercial importance for Brazil
