TL;DR: It is proposed that, in teleosts, ovarian 11- deoxycorticosterone and 11-de oxygencortisol may act as local hormones mediating the pituitary gonadotropin-induced maturation and ovulation of oocytes.
TL;DR: In this article, the first specimens of Coregonus cf. artedii and Microgadus tomcod are reported from calcareous nodules at Green Creek, and the occurrence of Osmerus mordax and fully plated Gasterosteus acule...

Abstract: SYNOPSIS. Sphaeromyxa maiyai sp. n. (Myxosporidea: Myxiidae) is described from the gall bladder of the Pacific tomcod Microgadus proximus Girard, from Newport, Oregon. The plasmodial stage is discoid averaging between 1 and 2 cm. The spore averages 27.6 × 5.6 μm in breadth, with pyriform polar capsules measuring 9.3 × 3.7 μm. Scanning electron microscopy reveals the presence of numerous longitudinal striations.
