East African Fisheries Research Organization Annual Report 1955/1956

This report covers the period 1st July, 1955, to 30th June, 1956. As printing has been delayed for various reasons, reference should be made to certain important proposals put forward since the 30th June. Just after the close of the year a meeting of the Lake Victoria Fisheries Board was held at Entebbe on 26th July. At this meeting disagreement arose between the representatives of the three East African Governments on the subject of whether or not existing restrictions on fishing in Lake Victoria should be retained. This organization holds strongly to the view that the existing restrictions on fishing should be retained, Kenya holds similar views, but Uganda and Tanganyika were in favour of a proposal to lift these restrictions. This question was discussed a month earlier by the Director with the Colonial Office Fisheries Advisory Committee and they also advised the Lake Victoria Fisheries Board against lifting the restrictions.

Heliconema savala n.sp. (Nematoda:Physalopteridae) from marine fish Lepturacanthus savala (Cuvier) (Trichiuridae) and Psettodes erumei (Schneider) new host (Pisces:Pettodidae) of Physalopterid Nematode, Bulbocephalus inglisi Rasheed, 1966 in Pakistan

Helicnonema savala, n.sp. obtained from the marine fish, Lepturacanthus savala in Sindh coast is distinguished from members of the genus processing in the male 10 tessellated longtitudinal ridges and a spicule ratio 1:15. Females have vulvular flap. Heliconema savala is a morphologically most closely related to Heliconema heliconema. The marine fish, Psettodes erumei is recorded as a new host of Bulbocephalus inglisi.

Light and scanning electron microscopic study of Balantidium ctenopharyngodoni Chen, 1955 (Class : Litostomatea) from China

Redescription of Balantidium ctenopharyngodoni "Chen (Acta Hydrobiol Sin 1:123-164, 1955)", collected from the hindgut of grass carp (Ctenopharyngodon idella), especially the segment of 6-10 cm upstream from the anus, from Honghu Lake, Hubei Province, central China in November 2005, is presented in this paper to complete Chen's description at both light and scanning electron microscopic levels. Some revisions were done: the vestibulum is fairly symmetrical, with compactly arranged cilia rather than assembled membrane bordering on the left vestibular side; four contractile vacuoles actually exist in the latter body, three of which surround the posterior portion of the macronucleus, whereas the fourth lies antero-left to it. Somatic monokinetids were compared among the species of genus Balantidium. The cysts were described, and possible infection routes of B. ctenopharyngodoni were also discussed.

Estudio del Cheilanthion hispanicae Rivas Goday 1955 em. Sáenz de Rivas & Rivas-Martínez 1979 y comunidades afines, en el Sector Orensano-Sanabriense (Provincia Carpetano-Ibérico-Leonesa)

Se analiza el comportamiento fitosociológico de las comunidades vegetales caracterizadas por la presencia de los taxones Cheilanthes tinaei Todaro y Ch. hispanica Mett. en el Sector Orensano-Sanabriense (Provincia Carpetano-lbérico-Leonesa), proponiendo para ellas la asociación Linario glabrescentis-Cheilanthetum tinaei y las subasociaciones: Linario glabrescentis-Cheilanthetum tinaei cheilanthetosum hispanicae nova y Linario glabrescentis-Cheilanthetum tinaei cheilanthetosum guanchicae nova.Comentamos brevemente la asociación Phagnalo saxatile-Rumicetum indurati Rivas-Martínez inéd, que contacta topográficamente con la asociación anteriormente propuesta.Se aportan datos sobre el comportamiento fitosociológico de Cheilanthes pteridioides (Reichard) C.

Nomenclature and syntaxonomic notes on some high-rank syntaxa of the European grassland vegetation

We present descriptions of a new order (Ranunculo cortusifolii-Geranietalia reuteri and of a new alliance (Stachyo lusitanicae-Cheirolophion sempervirentis) for the herbaceous fringe communities of Macaronesia and of the southwestern Iberian Peninsula, respectively. A new alliance, the Polygalo mediterraneae-Bromion erecti (mesophilous post-cultural grasslands), was introduced for the Peninsular Italy. We further validate and typify the Armerietalia rumelicae (perennial grasslands supported by nutrient-poor on siliceous bedrocks at altitudes characterized by the submediterranean climate of central-southern Balkan Peninsula), the Securigero-Dasypyrion villosae (lawn and fallow-land tall-grass annual vegetation of Italy), and the Cirsio vallis-demoni-Nardion (acidophilous grasslands on siliceous substrates of the Southern Italy). Nomenclatural issues (validity, legitimacy, synonymy, formal corrections) have been discussed and clarified for the following names: Brachypodio-Brometalia, Bromo pannonici-Festucion csikhegyensis, Corynephoro-Plantaginion radicatae, Heleochloion, Hieracio-Plantaginion radicatae, Nardetea strictae, Nardetalia strictae, Nardo-Callunetea, Nardo-Galion saxatilis, Oligo-Bromion, Paspalo-Heleochloetalia, Plantagini-Corynephorion and Scorzoneret alia villosae.
