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.

Ecology and Evolution, Volume 11, Issue 21, Page 14988-15003, November 2021., 2021 This paper proves that it is feasible to build artificial ecological islands in open water to increase the microhabitat heterogeneity and water‐level gradient as a means of ecological restoration, so as to provide more suitable habitats for aquatic organisms and thus increase the biological diversity of the ecosystem. Macrobenthos are the main food for

Structure of the vector tissue in piscicolid leeches (Annelida, Hirudinea, Rhynchobdellida, Piscicolidae) [PDF]
Journal of Morphology, 2006 AbstractHypodermic insemination occurs in piscicolid leeches (Hirudinea, Rhynchobdellida, Piscicolidae). The spermatophore is implanted in a specialized region of the leech body, the copulatory area. Just beneath the copulatory area, there is a specialized connective tissue (vector tissue) that is considered to guide the sperm toward the ovaries.

Zoologica Scripta, Volume 49, Issue 5, Page 614-640, September 2020., 2020 Abstract Clitellata is a major clade of Annelida comprising nearly all freshwater and terrestrial annelids as well as several marine species. We investigated clitellate phylogenetic relationships using transcriptomes sampled from 74 taxa (64 clitellates and 10 polychaetes), including multiple representatives of nearly all major clitellate higher taxa ...

A dataset of individual wet weights of benthic macroinvertebrates
Limnology and Oceanography Letters, Volume 9, Issue 6, Page 696-715, December 2024.Abstract Biomass estimates are crucial for modeling and understanding energy flow through ecosystems. Many modeling frameworks rely on published body weights of organisms to convert density estimates to biomass. However, published body weight data are limited to few taxa in a limited number of systems. Here we present mean individual weights for common
