Some problems of biotechnology for growing of larvae of giant freshwater prawn Macrobrachium rosenbergii (Decapoda: Palaemonidae)

open access: yesИзвестия ТИНРО, 2015
Giant freshwater prawn Macrobrachium rosenbergii (De Man, 1879) is cultivated in Crimea since 2000 and technology of complete cycle of its cultivation from planting material to saleable product is successfully applied nowadays.

Notes on the recent occurrence of uncommon pelagic “jellyfish” species in Maltese coastal waters [PDF]

open access: yes, 2010
There is a dearth of published works on sightings of uncommon pelagic jellyfish species within Maltese coastal waters, with a handful of disparate published reports and with most other existing relevant information being carried in newspapers and other

High‐Resolution Longitudinal eDNA Metabarcoding and Morphological Tracking of Planktonic Threats to Salmon Aquaculture

open access: yesEnvironmental DNA, Volume 6, Issue 5, September–October 2024.
In the current study, we present and assess an exhaustive approach to identify the planktonic drivers of farmed Atlantic salmon complex gill disease (CGD) and fish mortality. We explored delayed or “lagged” effects of plankton abundances on gill health and undertook a comparison of environmental DNA (eDNA) metabarcoding and microscopy in their ability ...

Non-indigenous hydromedusae in California's upper San Francisco Esturary: life cycles, distribution, and potential environmental impacts

open access: yesScientia Marina, 2000
Two species of hydromedusae, assumed to be native to the Black and Caspian Seas, were routinely collected in Suisun Slough, California, at the Suisun City Marina, during late summer and fall of 1997.

Variation Among Hydromedusæ

open access: yesScience, 1900
THE announcement of Bateson ('94), that "in the whole range of natural history there is no more striking case of the discontinuity and perfection of meristic variation than in the genus Sarsia, and the further proposition whether it is a mere coincidence that the specimens presenting this variation, so rare among the free-swimming Hydromedusae, should ...

The topological organization of the turtle cranium is constrained and conserved over long evolutionary timescales

open access: yesThe Anatomical Record, Volume 307, Issue 8, Page 2713-2748, August 2024.
Abstract The cranium of turtles (Testudines) is characterized by the secondary reduction of temporal fenestrae and loss of cranial joints (i.e., characteristics of anapsid, akinetic skulls). Evolution and ontogeny of the turtle cranium are associated with shape changes.

Review of Eastern Adriatic Hydromedusae: Unravelling Two Centuries of Records

open access: yesJournal of Marine Science and Engineering
The Eastern Adriatic Sea is biogeographically complex, yet knowledge of its hydromedusae is fragmented across two centuries of uneven sampling and shifting taxonomy.
