Structural characterization and in vitro biomedical activities of sulfated chitosan from Sepia pharaonis

International Journal of Biological Macromolecules, 2016
A low molecular weight sulfated chitosan (SP-LMWSC) was isolated from the cuttlebone of Sepia pharaonis. Elemental analysis established the presence of C, H and N. The sulfation of SP-LMWSC was confirmed by the presence of characteristic peaks in FT-IR and FT-Raman spectra.

Environmental Enrichment Accelerates the Ontogeny of Cryptic Behavior in Pharaoh Cuttlefish (Sepia pharaonis)

Zoological Science, 2016
We examined effect of environmental enrichment on cuttlefish, the most neutrally advanced invertebrate, to compare species variation of genetic and environmental influences. Cuttlefish were reared from seven to 117 days in one of three environments, namely, "poor" (artificial bottom without objects), "standard" (sandy bottom), and "enriched" (sandy ...

[Oxygen consumption rate of Sepia pharaonis embryos.]

Ying yong sheng tai xue bao = The journal of applied ecology, 2018
This research was conducted to unravel the variation of oxygen consumption rate during different developmental stages and the effects of different ecological factors on embryonic oxygen consumption rate of Sepia pharaonis. The oxygen consumption rates were measured at twelve deve-lopmental stages by the sealed volumetric flasks, and four embryonic ...

[Effects of light intensity and photoperiod on the embryonic development of Sepia pharaonis.]

Ying yong sheng tai xue bao = The journal of applied ecology, 2018
We investigated the effects of lumination on hatching of fertilized eggs of Sepia pharaonis, to reveal the best light conditions for its embryonic development. A single-factor experiment was carried out to examine the effects of different light intensities (10, 30, 50, 70, 90 μmol·m-2·s-1) and different photoperiod L:D (24 h:0 h, 18 h:6 h, 12 h:12 h, 6

Comparison in nutritional quality between wild and cultured cuttlefish Sepia pharaonis

Chinese Journal of Oceanology and Limnology, 2014
In this study, the proximate composition and the amino and fatty acid profiles of shrimp Litopenaeus vannamei (prey) and wild and cultured cuttlefish Sepia pharaonis (the latter fed the prey) were determined and compared with FAO/WHO recommendations.

Quality Evaluation in Chilled Cuttlefish(Sepia pharaonis)Fillets

Journal of Aquatic Food Product Technology, 2005
ABSTRACT The bacteriological, biochemical and sensory quality of cuttlefish (Sepia pharaonis) fillets chilled in ice was investigated. One lot was immediately iced (II) with flake ice at the ratio of 1:1 (wt/wt) and the other lot was left at room temperature of 32°C for 6 h and then iced and designated as delayed iced (DI).

A transcriptome resource for pharaoh cuttlefish (Sepia pharaonis) after ink ejection by brief pressing

Marine Genomics, 2016
Ink ejection is one of the most important defense mechanisms against external stimuli for pharaoh cuttlefish (Sepia pharaonis). The molecular changes during this process remain unknown. To understand the transcriptome changes after ink ejection by brief pressing, two cDNA libraries of pharaoh cuttlefish, from the inkjet group and control group were ...

Microbiological quality of Cuttlefish ( Sepia pharaonis ) fillets stored in dry and wet ice

Food Science and Technology International, 2012
Microbiological quality of cuttlefish ( Sepia pharaonis) fillets stored in three different ice conditions was studied. Fillets stored in wet ice at a ratio of 1:1 (package III) were sensorially acceptable for only 18 h, while that stored in dry ice at 1:1 (package I) and combination of dry ice and wet ice at 1:0.2:0.5 (package II ...

Octopuses (Octopus bimaculoides) and cuttlefishes (Sepia pharaonis, S. officinalis) can conditionally discriminate

Animal Cognition, 2007
In complex navigation using landmarks, an animal must discriminate between potential cues and show context (condition) sensitivity. Such conditional discrimination is considered a form of complex learning and has been associated primarily with vertebrates. We tested the hypothesis that octopuses and cuttlefish are capable of conditional discrimination.

Mating behaviors of pharaoh cuttlefish Sepia pharaonis

This study aimed to elucidate details of mating behaviors in the pharaoh cuttlefish S. pharaonis, with an emphasis on male behavioral adaptations that are related to sperm competition, such as sperm removal, mate guarding, and re-copulation. Observations in the laboratory showed that copulations occurred in the head-to-head position, and lasted about ...
