Anti-Predator Responses of Squid Throughout Ontogeny
… as components of anti-predator responses in squids. The goals of this study include: (1) examine the role of the lateral line analogue and vision in successful predator evasion; (2) measure kinematics of escape jetting; (3) document how chromatic patterning, posturing and inking in squid …

Designing a microhydraulically-driven mini-robotic squid
… I present the design of a miniature robotic "squid" which features the MEA as the driving component. The system was inspired by cephalopod paralarvae, which predominantly rely on jet propulsion in their early stages of development. The squid robot can produce thrust by diaphragm pump-like …

Magnetic Characterisation of Nanostructured Magnetic Systems Using SQUID Magnetometry
In this thesis SQUID magnetometry was employed as the main characterisation tool to investigate the magnetic behaviour of a number of materials on the bulk, nano- and atomic scale. In particular magnetic characterization was conducted on a selection of doped lanthanum manganate (LMO)magnetic …

Stock assessment of the Chokka Squid : Loligo vulgaris reynaudii
… to assess the status and productivity of chokka squid. Main hypotheses examined are the following: that the sharp decline in the trawl fishery catch per unit effort (CPUE) data in the early 1980s, reflects a real decline in the trawlers catch rate; that the decline in the trawl CPUE index is …

A Novel Squid Glaucoma microShunt for Controlled Release of Aqueous Humor
… clinical need, we developed a novel GDD, the Squid Glaucoma microShunt (SGS) which has been designed to release AH in a slow and controlled fashion. OBJECTIVE: The aims are to 1) review the chemical and physical properties of biocompatible polymers, 2) understand the properties of …

Constructing and Characterizing a Scanning SQUID Microscope for a Cryogen Free Dilution Refrigerator
Superconducting quantum interference devices, or SQUIDs, are highly sensitiveto magnetic flux and can be used to perform magnetic imaging at cryogenic tem- peratures. In this dissertation, I describe the first scanning SQUID microscope in a cryogen-free dilution refrigerator. First, I briefly …

Studies of magnetic vortices in superconductor networks and clusters by scanning SQUID microscopy
We have developed a Scanning SQUID Microscope (SSM) to study the configuration of trapped magnetic vortices in two-dimensional superconductor arrays and clusters. The SSM scans a dc SQUID detector over the array surface, achieving better than 10$\mu$m spatial resolution over a scan range up to 1cm …

Production of Restructured Squid and Scallops from Processing By-Products and Underutilized Species
North Atlantic short-finned squid (Illex illececbrosus) is an underutilized species and calico scallops (Argopecten gibbys) do not achieved the same market value as Sea scallops due to their small size. North Atlantic short-finned squid have limited consumer acceptability due to their smaller, …

The Socio-economic Impact Of The Squid Stock Volatility In The Eastern Cape Province Of South Africa
… of South Africa, each largely dependent on the squid fishery. The paper addresses four issues: (1) the operations of the squid industry in South Africa; (2) the local impacts of its operations; (3) the financial stability of the industry and (4) the manner in which the resource and the industry …

People, profits, and politics in the Eastern Cape chokka squid fishery: the socio-economics of an unstable resource
… socio-economic issues confronting the chokka squid fishery in South Africa's Eastern Cape, particularly in the towns of St Francis Bay, Humansdorp and Jeffreys Bay. It examines the implications of two key issues challenging the industry: the volatility of chokka squid catches, and the …

Physiological and behavioral responses, and their variability, in squid, Doryteuthis pealeii, embryos and paralarvae reared under chronic ocean acidification
… as nursery habitat. The inshore longfin squid, Doryteuthis pealeii, plays an important role in the northwest Atlantic food web, and annually lays its eggs in the nearshore benthos during summer. This thesis sought to characterize morphological, physiological, and behavioral responses of …

Assessing anthropogenic noise impacts and relevant soundscape cues for marine invertebrates: leveraging squid and coral reefs as model systems
… two facets: 1) behavioral responses of longfin squid, Doryteuthis pealeii to anthropogenic noise, and 2) particle motion of coral reef soundscapes in the U.S. Virgin Islands. In laboratory-based experiments I exposed D. pealeii to construction noise originally recorded from an offshore wind …

Exploring the Cephalopod Brain: Towards Mapping the First Whole Brain Connectome and Whole Animal Projectome of a Pygmy Squid
… hatchling, which belongs to the family of pygmy squids, the smallest known cephalopods, of dimensions suitable for whole-brain volume EM. Using eFIBSEM, small volumes of the eye and optic lobe were acquired to test the feasibility of mapping brain wiring, dependent on sample preparation …
