Cultured lobster olfactory receptor neurons (ORNs) were surveyed for their odor sensitivity with whole-cell, voltage-clamp recording. The nature of the adequate stimuli, the degree of tuning (response spectra) of the cells, the threshold of sensitivity and the dual polarity of the odor-evoked currents are consistent with chemosensitivity in the cultured ORNs being olfactory. The ability of odor...

In October 2007, the Regional Director-General (RDG), Maritimes Region, announced a number of priorities for the Maritimes lobster fishery, including improving conservation measures to provide better protection for large mature female lobsters in particular. At a meeting with the lobster industry in September 2008 to discuss potential new measures, industry raised questions about the biological...

copper is most toxic metal in marine organisms. characterization of protein occurring in the metabolically active tissues of muscle (mu), hepatopancreas (hp) and gills (gl) of the spiny lobster, panulirus homarus homarus on exposure to two sub-lethal doses (9.55 and 19.1 µg/l) of copper were studied for 28 days of exposure (doe). the electrophoretic pattern of muscle, hepatopancreas and gill pr...

As a continuation of the Doctoral Service 2021 activity that was carried out by this team last year at POKDAKAN Pesona Bahari, solution offered is to design culture container providing insulation between individual lobsters being cultivated, as well more "rooms"/spaces with Underwater Lobster. Appartment.. lobster apartment latest technology in rearing cultivation modification basic cages. Lobs...

The objective of this study was to isolation and characterization of Listeria species and determines Listeria monocytogenes serotypes in fresh fish, shrimp, crab and lobster in Isfahan and Shahrekord, Iran. From September 2010 to April 2011, a total of 300 samples of fresh fish, shrimp, crab and lobster were obtained from randomly selected retail stores in Isfahan and Shahreko...

Acquisition and retention of a shelter by a lobster are two of the variables that play a role in lobster agonistic interactions. Since shelter procurement and retention are important for lobster survival, behaviors related to this activity frequently outrank other daily behaviors (e.g., searching for food). Here, we examine the effects of time in residence on the parameters of the escape respon...

We conducted laboratory experiments to investigate interpopulation differences in the behavioural responses of the whelk Buccinum undatum to the predatory lobster Homarus americanus and the asteroid Leptasterias polaris, both in the absence and presence of feeding opportunities. Whelks from three populations in the eastern North Atlantic (1) responded to lobsters by displaying avoidance behavio...

A variety of extraction procedures were evaluated for the extraction of arsenic and other analytes from lobster tissue samples using inductively coupled plasma mass spectrometry (ICP-MS) detection. Soxhlet, room temperature mixing, sonication, microwave assisted, supercritical carbon dioxide and subcritical water extractions were evaluated for a variety of solvent systems and optimum conditions...

Crustaceans exhibit a remarkable variation in their feeding habits and food type, but most knowledge on carbohydrate digestion and utilization in this group has come from research on few species. The aim of this study was to make an integrative analysis of dietary carbohydrate utilization in the spiny lobster Panulirus argus. We used complementary methodologies such as different assessments of ...
