Parasites of endemic and introduced fishes of Zaianderud River of the Esfahan

In this research, 9 species of local and introduced fishes of the Zayandehroud River in Esfahan province (in the Sarmatian region belonging to the large paleoarctic fauna) in 6 seasons (winter 2003, spring, summer, autumn and winter 2004 and summer 2005) were parasitologically studied. The local fishes included alburnoides bipunctatus, Alburnus maculatus, Aphanius vladykovi, Capoeta aculeata & Capoeta damascina & the introduced fishes included Aristichthys nobilis, Carassius auratus, Ctenopharyngodon idella and Cyprinus carpio. Upon being hunted, the fishes were transferred alive to Esfahan Aquatics Breeding Center and physiologically studied after the determination of their species and genus by identification keys Berg (30), Coad (31), Saadati (51), Abdoli (20) and Holchic (38). 32 species of parasites were totally identified as follows: 6 Protozoan species including Ichthyophthirius multifiliis, 5 Trichodina species, 2 Myxobolus species including Myxobolus cristatus & Myxobolus saidovi, 16 monogenea species including Dactylogyrus alatus. D. anchorutus, D. baueri, D. chalcalburni, D. chramuli, D. extensus, D. gracilis, D. lamellatus, D. lenkorani and D. pukher, 4 Dactylogyrus spp. 2 Gyrodactylus species, 1 species of Digenea, Diplostomum spthaceum, 4 species of Cestoda including Bothriocephallus gowkongensis, khawia armeniaca, Ligulaintestinalis. Caryophyllaeus sp. 1 Acanthocephala: Acanthocephalo rhynchoides cholodkowsky, 2 species of the crustaceans including the mature & copepodian stages of Lernaea cyprinacea & 1 sp of the genus Lamproglena. Out of all the 166 pcs of the fishes hunted in this research, 127 fishes (76.5%) were infected, and 39 fishes (23.50%) were not infected. In the fishes studied, having 14 of 32 species of the parasites identified, Capoeta aculeata displayed the most variety of infection, and having only 1 sp of the parasites. Aristichthys nobilis displayed the least variety of infection. The new findings of the research will follow: Myxobolus saidovi sp is reported for the 1st time from Iran's fresh water fishes, Alburnus maculatus and Capoeta aculeata are new hosts for M. saidovi and M. cristatus, respectively. Regarding monogenea Capoeta damascina & C. aculeata were reported as the new hosts for parasite D. pukher. The presence of D. pukher the infection of Capoeta aculeata with D. chramuli, D. lenkorani and D. gracilis in the Zayandehroud river were the 1st report. Regarding the Cestodea, Bothriocephalus gowkongensis was reported to be hosted by Aphanius Vladykovi for the 1St time in Iran.

Genetic improvement and utilisation of indigenous tilapia in southern Africa: final technical report, December 1st 1998 to June 31st, 2002

Mozambique tilapia (Oreochromis mossambicus) is an indigenous tilapia species in southern Africa, until now the majority of genetic research has been carried out on Asian species of tilapia but this project aims to look at this African species. Those most suited to further development in aquaculture in southern Africa have now been identified. The genetic characterisation of strains has been completed. This information has aided the choice of strains for use in small scale aquaculture and for genetically male tilapia (GMT) production. They will form the basis of future strategies for further genetic improvement, and management of genetic diversity of Mozambique tilapia. The information will also contribute towards responsible management and development of genetic resources, particularly with regard to indigenous species of tilapia. Good progress has been made with the adaptation and implementation of producing the supermale fish required to produce all male offspring, resulting in faster growing populations of tilapia. The presence of the project and its associated activity has been a catalyst for a surge in interest in tilapia culture throughout southern Africa. [PDF contains 183 pages]

Results of the Austrian-Ceylonese hydrobiological mission 1970 of the 1st Zoological Institute of the University of Vienna (Austria) and the Department of Zoology of the Vidyalankara University of Ceylon, Kelaniya. Pt. 1. Preliminary report: introduction and description of the stations

The Austrian-Ceylonese hydrobiological mission of 1970 investigated and made collections from 36 flowing water systems (brooks, torrents, rivers); of these, 34 water systems were in the mountains regions of south-west and south-east of Sri Lanka. In the crystalline mountain region, the water systems are extremely poor in electrolytes, very soft and slightly acid; these torrential streams have strong falls, high flow velocities and boulder bottoms. The water temperatures increase from the sources and brooks at 2,000 m altitude to the mouths from 15°C to 28°C. The density of animal population (macro and meso-fauna) increases from the river bank regions (and pools) towards the sections with strong current and reaches on the rocks in the cascades a density of 500 to appr. 750 individuals/1/16m².

Annual Report of the Game and Fisheries Department for the period 1st July 1956 to 30th June, 1957

This report continues to cover the period of the financial year. Although, as before, for the sake of continuity and accuracy many of the statistics refer to the calendar year. The year has been notable in particular for the launching of extensive research projects on wild-life conservation problems, and much progress has already been made. This has been rendered possible by the greatly appreciated help and interest of the Fulbright Commission, who arranged for three experienced American wild-life scientists to work on these problems in Uganda. The latter have been working in conjunction with The Game and Fisheries Department's Biologist, as a team under the general Direction of the recently created Fauna Research Committee.

Rivers Taw and Torridge scale reading investigation. 8th annual report for the 1972 season

This is the Rivers Taw and Torridge scale reading investigation: the 8th annual report for the 1972 season produced by Devon River Authority in 1973. The object of the investigation is to examine by means of scale reading the biology of age classes of the salmon populations of the Rivers Taw and Torridge. The report is arranged in sections as previously and tables referred to in the report form an appendix. Scales were collected only from fish taken during the normal open season, which in 1972 was 1st April - 31st August. A weekly close time was in operation for the nets, a period of 60 hours from 6 p.m. on Friday evening to 6 a.m. on the following Monday. Thirty six licences for draft or seine nets were issued for the 1972 season and netsmen submitted samples of scales collected direct.

Year 1 operational report: Improving employment and income through development of Egypt’s aquaculture sector(IEIDEAS) project

Implementation of the SDC funded project ‘Improving Employment and Income through Development of Egypt’s Aquaculture Sector’ commenced on 1st December 2011 and will continue until late 2014. This report summarizes the results of the first 10 months until 30th September 2012. The project was based on a value chain analysis carried out by WorldFish in September 2011. The information in the VCA acts as the baseline for the main project parameters. It established that the aquaculture value chain is a significant employer (14 FTE per 100 tonnes of annual production), particularly in rural areas and there was scope to increase employment of youth and women.

Results of the Austrian-Ceylonese hydrobiological mission 1970 of the 1st Zoological Institute of the University of Vienna (Austria) and the Department of Zoology of the Vidyalankara University of Ceylon, Kelaniya. Pt. 7. Dryopidae and Elminthidae of Ceylon

This report comprises a summary of parasitic copepods from fishes in Ceylon, as isolated from the branchial material of fishes belonging to previous collections. Seven copepod species are described in detail, as well as one species of Branchiura and one species of Isopoda. Caution is advocated to avoid further introductions via parasite-infested fishes, since only four of the above species are endemic.

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.
