The Effects of Noise on the Juvenile Life Stage of Crustaceans: Behavioral, Cellular, and Molecular Responses in Procambarus clarkii

open access: yesIntegrative Zoology, EarlyView.
Juvenile Procambarus clarkii exposed to noise exhibited behavioral changes, shifts in enzymatic activity, and altered expression of stress and immune genes. The findings highlight the sensitivity of invertebrate juveniles to anthropogenic acoustic pollution.

Effect of fenitrothion on reproduction of the freshwater prawn Macrobrachium lamerrii

open access: yesEcotoxicology and Environmental Safety, 1986
Acute and toxic effects of fenitrothion on eggs and larvae of Macrobrachium lamerrii have been studied. The hatching success of the eggs is not affected when berried females are exposed to fenitrothion. No drastic changes in egg production are seen at sublethal levels, while at higher concentrations females abort their eggs.

Fishing Activity Affected Odontocete Cetacean Distribution in a Marine Protected Area in the East China Sea

open access: yesIntegrative Zoology, EarlyView.
Spatiotemporal distribution of odontocete cetaceans within China's Jiushan Archipelago National Nature Reserve was investigated. Fishing vessels significantly reduced both cetacean acoustic detections and feeding activity, whereas gillnets selectively suppressed cetacean feeding behavior without affecting overall cetacean detection rates.

Status of freshwater prawn farming: a review

open access: yesAquaculture Research, 1995
Farmed freshwater prawn production globally expanded by a factor of 3.5 in the 7 years from 1984 to 1991 but declined by 17% to 31 235 tin 1992. This was caused by a 53% reduction in the output of Taiwan due to disease and in-breeding problems, partially compensated by increases elsewhere, notably in India and Vietnam. This paper reviews the scientific

Production of freshwater prawns in the Mekong Delta [PDF]

open access: yesNaga, 1992
Currently there are 2 sources of freshwater prawn Macrobrachium rosenbergii production in Vietnam - natural production from the rivers and canals and aquaculture production from ponds and ricefields. An account is given of the production of this prawn in the Mekong Delta.

Investigating relationships among strontium, barium, and seasonality in wild baboons

open access: yesArchaeometry, EarlyView.
Abstract Geochemical profiles of Australopithecus africanus and baboon teeth show fluctuating trace elements, possibly reflecting seasonal diets. Here we use laser ablation–inductively coupled plasma–mass spectrometric measurements of calcium‐normalized strontium and barium ratios (Sr/Ca and Ba/Ca) and ion microprobe analyses of oxygen isotopes (δ18O ...

Selective breeding program for genetic improvement of Macrobrachium rosenbergii in Thailand. [PDF]

open access: yes, 2005
Although the giant freshwater prawn (Macrobrachium rosenbergii) has been domesticated in Thailand for over decades, appropriate selective breeding program has yet to be achieved. Good quality seeds for the Machrobrachium aquaculture industry is therefore

Total and Inorganic Arsenic in Freshwater Fish and Prawn in Thailand

open access: yesJournal of Food Protection, 2012
Total and inorganic arsenic levels were determined in 120 samples of eight freshwater animal species collected from five distribution centers in the central region of Thailand between January and March 2011. Eight species with the highest annual catch, consisting of seven fish species and one prawn species, were analyzed.

Geometric Morphometrics Reveal Body Shape Variation in Freshwater Shrimps of the Genus Macrobrachium Lacking a Mandibular Palp (Formerly Pseudopalaemon Sollaud, 1911) (Decapoda: Palaemonidae)

open access: yesActa Zoologica, EarlyView.
ABSTRACT Shape variation in the cephalothorax of Macrobrachium species without mandibular palp using geometric morphometrics was used as a tool to support species differentiation and propose new diagnostic characters for taxonomic identification.

Contributions to the Knowledge of the Larval Morphology of Synalpheus Spence Bate, 1888 (Caridea: Alpheidae): Description of the First Zoea of S. antillensis Coutière, 1909 and S. cf. townsendi Coutière, 1909 Reared in Laboratory

open access: yesActa Zoologica, EarlyView.
ABSTRACT The first zoea of two Synalpheus species, namely: S. antillensis and S. cf. townsendi, are herein described. They were also compared with the genus descriptions and with their respective species complexes available in the literature. Morphological information on Synalpheus zoea I exhibits an increase from 19 to 21 species, and it corresponds ...
