Item Salt based dry fish processing and marketing by fishers of Minneriya reservoir in Sri Lanka(Postgraduate Institute of Agriculture, University of Peradeniya:Peradeniya, 2012) Sugathapala, R.M.N.S.; Suntharabarathy, T.V.; Edirisinghe, U.Item Determination of suitability of egg deposition materials and development of larval feeds for higher growth and survival of common carp (Cyprinus carpio L)(Postgraduate Institute of Agriculture, University of Peradeniya:Peradeniya, 1999) Hirimuthugoda, N.Y.; Edirisinghe, U.; Gunawardana, A.Item Feeding behaviour and acceptability of different feeds by Puntius nigrofasciatus(Postgraduate Institute of Agriculture, University of Peradeniya:Peradeniya, 1999) Weerasooriya, A.C.; Edirisinghe, U.; Silva, P.; Dematawewa, C.M.B.Item Morphology and some biological aspects of common spiny or lesser loach (Lepidocephalichthys thermalis) and banded mountain or spotted loach (Schistura notostigma) of Sri Lanka(Postgraduate Institute of Agriculture, University of Peradeniya:Peradeniya, 2001) Sundarabarathy, T.V.; Edirisinghe, U.; Dematawewa, C.M.B.; Nandasena, K.G.Item Comparison of length-weight relationships and fecundity between pond cultured and reservoir (Victoria) inhabiting common carp (Cyprinus carpio)(Univeristy of Ruhuna. Kamburupitiya, 1998) Nathanael, S.Comparisons were made on the length weight relationships, fecundity and egg diameter distribution of yolked ova in mature ovaries of pond cultured female common carp with those collected during the same period from the Victoria reservoir. Irrespective of the location, the condition factor of gravid females was within the range 1.6-2.0. However, the average body condition of ripe females from the reservoir was better than those from the pond. Yolked ova in ripe (Stage vi) ovaries had a diameter between 0.85 to 1.70 mm. The single mode indicates that the ova ripen simultaneously and are shed in a single batch. Fecundity is linearly related to body and gonad weight, and curvilinearly to body length. Fecundity of pond cultured females with a length of 30.8 to 46.0 cm had a fecundity between 49, 070 and 240, 100 Irrespective of the location, the fecundity of females within the same length group were within the same range. The presence of larger sized females with a correspondingly high fecundity and good body condition which produce heavily yoilked eggs indicated that under the prevailing conditions, there is potential for the establishement of a common carp based fishery in large , deep reservoirs like the Victoria, Development of pond culture to re-stock heavily depleted reservoirs with fingerlings is therefore feasible.Item A New Marine ARGULUS (Copepoda, Branchiura)(University of Peradeniya. Peradeniya, 1959) Kirtisinghe, P.Item Reproductive ecology of two co-occuring, stream-dwelling, endemic carplets (Pisces, Cyprinidae) of Sri Lanka(University of Peradeniya. Peradeniya, 1994) De Silva, K.H.G.M.Item Aspects of the food and feeding biology of the yellow mahseer Tor khudree (Sykes) (Osteichthyes, Cyprinidae) in Sri Lanka(University of Peradeniya. Peradeniya, 1995) De Silva, P.K.; Amerasinghe, D.Item Observation on the structure and life-cycle of the digenetic fish-trematode Transversotrema patialense (Soparkar)(University of Peradeniya. Peradeniya, 1964) Crusz, H.; Ratnayake, W.E.; Sathananthan, A.H.Progenetic, egg-laden metacercariae of the trematode Transversotrema patialense (Soparkae, 1924) (Digenea: Transversotrematidae) have been recovered from under the scales of the freshwater fish Ophicephalus bloch and Macopodus cupanus (Cuv. et Val.) Caught in Batalagoda, Ceylon. The fish O. punctatus , M. cuponus and Tilapia mossambica (Peters) have been infected in the laboratory with the cercariae of this trematode, emitted by snails of the species Melanoids tuberculata (Muller). Many of the mrtacercariae that developed under the scales of these fish had ripe eggs. Uninfested, laboratory-bred snails of the same species became infested with radiae and cercariae of T. patialense, after exposure to fish carrying the matacercariae. At no stage were the metacercariae found to be eneysted. The mature metacercariae has been more precisely observed and described.Item Changes in starch-gel electrophoretic pattern of serum proteins of a freshwater teleost channa punctatus (bloch), exposed to sublethal and chronic levels to three organophosphorus insecticides(University of Peradeniya. Peradeniya, 1974) Annees, M.A.
