Gill histopathology of cultured European sea bass, Dicentrarchus labrax (L.), infected with Diplectanum aequans (Wagener 1857) Diesing 1958 (Diplectanidae: Monogenea)
In infected fish, cellular changes in the epithelium underlying the bodies of worms were noted typified by an elevation in the number of mucous and rodlet cells and a reduction in the numbers of chloride cells. Expand
Economic costs of protistan and metazoan parasites to global mariculture
This study examines the world's major marine and brackish water aquaculture production industries and provides estimates of the potential economic costs attributable to a range of key parasite pathogens using 498 specific events for the purposes of illustration and estimation of costs. Expand
Phylogenetic and antigenic characterization of new fish nodavirus isolates from Europe and Asia.
Phylogenetic analysis based on the nucleotide sequence of the coat protein classified the majority of these new isolates to the RGNNV genotype, supporting the possibility that the different nodavirus genotypes can also be serologically distinguishable. Expand
Review of climate change impacts on marine aquaculture in the UK and Ireland
Marine aquaculture relies on coastal habitats that will be affected by climate change. This review assesses current knowledge of the threats and opportunities of climate change for aquaculture in theExpand
Survey of actinosporean types (Myxozoa) belonging to seven collective groups found in a freshwater salmon farm in Northern Scotland.
A study of the actinosporean fauna of oligochaetes from a freshwater salmon farm in Northern Scotland was carried out from October 1996 to August 1998 and found twenty-one types, including one type of triactinomyxon, which was released from unidentified immature oligoch aetes. Expand
The use of morphometric characters to discriminate specimens of laboratory-reared and wild populations of Gyrodactylus salaris and G. thymalli (Monogenea).
Populations of Gyrodactylus identified by mtDNA can also be discriminated using morphometric landmark distances, according to morphometric methods. Expand
Nominal species of the genus Gyrodactylus von Nordmann 1832 (Monogenea: Gyrodactylidae), with a list of principal host species
While the majority of Gyrodactylus species (59%) are recorded from single hosts, some have a much broader broad range and need to be considered for inclusion in a broader range classification. Expand
Isolation of nodavirus from Scottish farmed halibut, Hippoglossus hippoglossus (L).
Fish nodaviruses belonging to the genus betano-davirus are the aetiological agents of viral nervousnecrosis (VNN), also referred to as viral encephalo-pathy and retinopathy (VER), or fishExpand
Description of three new species of Gyrodactylus von Nordmann, 1832 (Monogenea) parasitising Oreochromis niloticus niloticus (L.) and O. mossambicus (Peters) (Cichlidae)
It is confirmed that Nile and Mozambique tilapia harbour a number of different species of Gyrodactylus, with G. cichlidarum being the most frequently encountered and being associated with mortalities of juvenile O. n. Expand
The anti-protozoal activity of bronopol on the key life-stages of Ichthyophthirius multifiliis Fouquet, 1876 (Ciliophora).
It is demonstrated that bronopol (Pyceze™) affects the survival of all free-living stages of I. multifiliis (protomonts, tomont and theronts), thus suggesting that Bronopol may serve a useful role in the control ofI. Expand
