A global review of problematic and pathogenic parasites of farmed tilapia

Reviews in Aquaculture, Volume 15, Issue S1, Page 92-153, February 2023., 2023
Abstract Over the past 80 years, tilapia have been translocated globally for aquaculture; active production is recorded in >124 countries. Of 7 million tonnes of tilapia produced in aquaculture, 79% is from 79 countries outside the natural range of tilapia.

Natural Biota’s Contribution to Cultured Aquatic Animals’ Growth in Aquaculture Cannot Be Ignored

Aquaculture Research, Volume 2023, Issue 1, 2023., 2023
The rapid expansion of the aquaculture industry is accompanied by high organic and nutrient loadings from formulated feeds. This leads to water deterioration and pathogenic microorganisms. Natural biota (e.g., bacteria, phytoplankton, zooplankton, and zoobenthos) in ponds form important parts of cultured aquatic animals’ diets.

Neglected symbionts and other metazoan invertebrates associated with molluscs from Africa's largest lake: Diversity, biotic interactions and bioindication

Freshwater Biology, Volume 67, Issue 12, Page 2089-2099, December 2022., 2022
Abstract Freshwater molluscs are hosts for diverse metazoan symbionts. However, apart from the digenean helminths, symbionts of molluscs are underreported worldwide. Therefore, this study focused on the diversity of oligochaetes, leeches, mites, insect larvae and nematodes associated with gastropods and bivalves from Lake Victoria, East Africa. Overall,

Identification of proteins from the secretory/excretory products (SEPs) of the branchiuran ectoparasite Argulus foliaceus (Linnaeus, 1758) reveals unique secreted proteins amongst haematophagous ecdysozoa

Parasites & Vectors, 2020
Background It is hypothesised that being a blood-feeding ectoparasite, Argulus foliaceus (Linnaeus, 1758), uses similar mechanisms for digestion and host immune evasion to those used by other haematophagous ecdysozoa, including caligid copepods (e.g. sea

Development of a flow‐sensitive macroinvertebrate index for Australian rivers

River Research and Applications, Volume 38, Issue 5, Page 846-862, June 2022., 2022
Abstract Hydrologically sensitive macroinvertebrate indices have been developed in Europe, the Americas and New Zealand to serve many purposes such as monitoring ecological responses to drought, flow regulation, water extraction and the provision of environmental flows.

The potential of aquatic bloodfeeding and nonbloodfeeding leeches as a tool for iDNA characterisation

Molecular Ecology Resources, Volume 22, Issue 2, Page 539-553, February 2022., 2022
Abstract Leeches play important roles in food webs due to their abundance, diversity and feeding habits. Studies using invertebrate‐derived DNA (iDNA) extracted from leech gut contents to target vertebrate DNA have focused on the Indo‐Pacific region and mainly leveraged the leech family Haemadipsidae, composed of bloodfeeding terrestrial leeches, while

Investigation on parasitic infestation of Labeo rohita (Hamilton, 1822) in the south-western region of Bangladesh. [PDF]

Vet Med Sci
Over the study, 180 L. rohita specimens were examined,, revealing the presence of six distinct parasite species, consisting of endoparasites. Through microscopic examination, a total of 323 parasites were investigated, categories including Cestode, Nematode, Acanthocephala, Trematode and Digenia, predominantly residing in the intestines and liver of L.
