New records of nine monogenean parasites infesting non‐native freshwater fish species in New Zealand
New Zealand Journal of Marine and Freshwater Research, Volume 59, Issue 5, Page 1052-1068, December 2025.ABSTRACT Twenty‐one non‐native freshwater fish species have established populations in New Zealand, yet only two have been reported with monogenean infestations; grass carp, Ctenopharyngodon idella (Valenciennes in Cuvier and Valenciennes, 1844) and western mosquitofish, Gambusia affinis (Baird and Girard, 1853), each with two identified monogenean ...

Observations on the food and the gut pigment of the Polyopisthocotylea (Trematoda: Monogenea)
Parasitology, 1954 1. It has been shown by spectroscopic and histochemical methods that eight representative species of Polyopisthocotylea feed mainly on the blood of their hosts.2. The blood is probably haemolysed fairly rapidly and subsequently absorbed by amoeboid ingestion, the globin moiety of the haemoglobin forming the chief nutriment of the parasite and the ...

Ultrastructure of spermiogenesis and spermatozoa ofPolylabroides australis(Platyhelminthes, Monogenea, Polyopisthocotylea, Microcotyudae) [PDF]
Parasite, 1994 Testis follicles are surrounded by a sheath and conlain several stages of spermatogenesis. Primary spermatocytes have large nuclei with a loose granular appearance and synaptonemal complexes, and their densely packed cell bodies are small and rich in mitochondria.

Aquaculture Research, Volume 2025, Issue 1, 2025.The increase in fish production in aquaculture reflects the growth of the world population. However, this expansion is accompanied by challenges, such as the intensification of production systems through increased stocking density, which induces stress in fish, weakening their immune system and making them more susceptible to disease outbreaks ...

Fish host-monogenean parasite interactions, with special reference to Polyopisthocotylea [PDF]
, 2008 Teleost fishes possess immune systems capable of mounting humoral and cellular responses against pathogens, both specific and non-specific. Monogenea (Platyhelminthes) are common ectoparasites of fish, and can have significant pathogenic effects on hosts,

Reviews in Aquaculture, Volume 16, Issue 1, Page 287-308, January 2024.Sparicotylosis has been present in Mediterranean aquaculture of the gilthead seabream for the past 25 years, yet disease management and treatments are not effective. This is further jeopardised by global warming and resistance of Sparicotyle chrysophrii to available anthelminthic compounds.

Microhabitat selection of Discocotyle sagittata (Monogenea: Polyopisthocotylea) in farmed rainbow trout [PDF]
, 2008 Microhabitat preference of the monogenean Discocotyle sagittata (Leuckart, 1842) was determined in late spring and late autumn in rainbow trout, Oncorhynchus mykiss (Walbaum), reared in the Isle of Man, UK. Discocotyle sagittata exhibits a preference for
