On the nutrition of Polyphemus pediculus (L.). [Translation from: Trudy Instituta Biologii Vnutrennykh Vodnany 12(15) 170-174, 1966.] [PDF]

, 1966
Many sides of the biology of Polyphemus pediculus are adequately studied at the present time. Most complicated is the question of its feeding. Dissection does not give an idea of the composition of the food, since Polyphemus strongly grinds its food with

AQUA‐FINS: Advanced Quantitative Underwater Analysis by a Flexible Integrated Nitrate Sensor

Advanced Sensor Research, EarlyView.
This work presents a flexible, integrated sensor array for real‐time monitoring of nitrate, pH, and temperature in aquaculture. The sensors exhibit high sensitivity and selectivity, while a regression model improves nitrate detection accuracy in dynamic conditions. Successful field deployment of the sensor array highlights its potential for maintaining

Toxicity of avermectin to Eriocheir sinensis and the isolation of a avermectin-degrading bacterium, Ochrobactrum sp. AVM-2

Ecotoxicology and Environmental Safety, 2022
Avermectin is widely used in the prevention and treatment of parasites diseases in aquaculture. However, the residual avermectin has a serious impact on the growth and quality of aquatic animals including Eriocheir sinensis.

A Novel Design and Evaluation of a Dactylus-Equipped Quadruped Robot for Mobile Manipulation [PDF]

arXiv, 2022
Quadruped robots are usually equipped with additional arms for manipulation, negatively impacting price and weight. On the other hand, the requirements of legged locomotion mean that the legs of such robots often possess the needed torque and precision to perform manipulation.

Flow cytometric characterization of freshwater crayfish hemocytes for the examination of physiological status in wild and captive animals [PDF]

, 2009
Enumeration of invertebrate hemocytes is a potentially powerful tool for the determination of physiological effects of extrinsic stressors, such as hypoxia, disease, and toxicant exposure.

Shrimp Virus Regulates ROS Dynamics via the Nrf2 Pathway to Facilitate Viral Replication

Advanced Science, EarlyView.
Viruses manipulate host ROS as a strategy to achieve successful infection. WSSV exploits Nrf2 pathway to maintain ROS homeostasis and establishes a positive feedback loop to facilitate WSSV replication. Wsv220 competitively binds to Keap1 to activate Nrf2. Nrf2 up‐regulates LvG6PDH to produce more NADPH and GSH to eliminate excessive ROS.

Non‐lethal sampling does not misrepresent trophic level or dietary sources for Sagmariasus verreauxi (eastern rock lobster)

Rapid Communications in Mass Spectrometry, Volume 37, Issue 4, 28 February 2023., 2023
Rationale Isotope analysis can be used to investigate the diets of predators based on assimilation of nitrogen and carbon isotopes from prey. Recent work has shown that tissues taken from legs, antennae or abdomen of lobsters can give different indications of diet, but this has never been evaluated for Sagmariasus verreauxi (eastern rock lobster).

A C1qDC Protein (HcC1qDC6) with Three Tandem C1q Domains Is Involved in Immune Response of Triangle-Shell Pearl Mussel (Hyriopsis cumingii)

Frontiers in Physiology, 2017
C1q-domain-containing (C1qDC) proteins are a family of proteins with a globular C1q (gC1q) domain and participate in several immune responses. In this study, a C1qDC gene was identified from the triangle-shell pearl mussel Hyriopsis cumingii (designated ...

Sounds of a changing sea: Temperature drives acoustic output by dominant biological sound-producers in shallow water habitats

Frontiers in Marine Science, 2022
The ocean’s soundscape is fundamental to marine ecosystems, not only as a source of sensory information critical to many ecological processes but also as an indicator of biodiversity and habitat health. Yet, little is known about how ecoacoustic activity
