A review of the biology of the jumbo squid Dosidicus gigas (Cephalopoda: Ommastrephidae)

Fisheries Research, 2001
Abstract The taxonomy, functional morphology, evolutionary biology and ecology of the jumbo squid, Dosidicus gigas, were reviewed using the data from many Soviet/Russian expeditions and all available literature. D. gigas is one of the largest and most abundant of the nektonic squid in the epipelagic zone of the world Ocean.

Jumbo squid beaks: Inspiration for design of robust organic composites

Acta Biomaterialia, 2007
The hard tissues found in some invertebrate marine organisms represent intriguing paradigms for robust, lightweight materials. The present study focuses on one such tissue: that comprising the beak of the jumbo squid (Dosidicus gigas). Its main constituents are chitin fibers (15-20wt.%) and histidine- and glycine-rich proteins (40-45%).

PROTEIN SOLUBILITY AND PRODUCTION OF GELS FROM JUMBO SQUID

Journal of Food Biochemistry, 2009
Solubility at several ionic strengths (0 to 1.0 M), pH (2 to 13) and gelling capacity of jumbo squid Dosidicus gigas muscle proteins were evaluated. Protein recovery was >90% at pH 9–12. Autohydrolysis was evaluated and affected only sarcoplasmic proteins. Folding score was 5 on all gels. Strength was higher for thermal gels prepared from squid fin (50.

EFFECT OF pH AND TEMPERATURE ON JUMBO SQUID PROTEINS

Journal of Food Biochemistry, 2009
Evaluation of the effect of pH (2 to 13) and temperature (0 to 50C) on functional properties of jumbo squid proteins was performed, followed by a 2 × 3 factorial design for producing squid protein hydrolysates bearing useful functional properties. In particular, the effects of pH (8, 9 and 10) and temperature (30, 35, 40C) were evaluated.

Paralarvae of the jumbo squid, Dosidicus gigas

Invertebrate Biology, 2010
Abstract. The rhynchoteuthion stage of the jumbo squid, Dosidicus gigas, has morphological characteristics similar to the paralarvae of the purpleback squid, Sthenoteuthis oualaniensis, making it difficult to determine the locations, seasons, and conditions where spawning of jumbo squid occurs. In this study, 180 paralarvae of D.

Iteroparity or Semelparity in the Jumbo Squid Dosidicus gigas: A Critical Choice

Journal of Shellfish Research, 2019
The jumbo squid Dosidicus gigas was recently claimed to be an iteroparous species with ovaries returning to an immature, resting stage after spawning. Analysis of the data and figures presented in two recent articles revealed that this claim was based on misinterpretation of histological information and that Dosidicus is not iteroparous.

Protein isolates from jumbo squid (Dosidicus gigas) by pH-shift processing

Process Biochemistry, 2009
There is a growing interest in adding value to the jumbo squid Dosidicus gigas fishery. This work describes two extraction procedures for processing muscle to obtain protein isolates with suitable functional properties. The effect on muscle protein solubility and protein recovery of combining freezing and grinding raw materials during storage was ...

Jumbo SquidDosidicus gigas: A New Fishery in Ecuador

Reviews in Fisheries Science & Aquaculture, 2015
During 2014 given the relevance of Dosidicus gigas in the eastern Pacific and the incentives and possible profits obtained for harvest of jumbo squid, the Ecuador Government decided that D. gigas must be a new fishery. So, in this article, the first steps to fishery management and the future directions for jumbo squid fishery in Ecuador are documented.

Environmental effects on the jumbo squid fishery along Baja California’s west coast

Fisheries Science, 2016
Since 2000, jumbo squid Dosidicus gigas catches in Baja California have increased steadily with a record catch in 2011 of 14,243,689 kg. However, little is known about stock size, distribution and seasonality, as well as the possible effects of the environment on the fishery. We tested D.

Population genetic structure of jumbo squid (Dosidicus gigas) evaluated by RAPD analysis

Fisheries Research, 2007
Abstract The jumbo squid ( Dosidicus gigas ) supports important fisheries, with the maximum landings being recorded in Mexico, Peru and Chile. To evaluate genetic structure and to measure the impact of temporal variation, randomly amplified polymorphic DNA (RAPD) data were generated and analysed from 210 samples from eight eastern Pacific sites and ...
