Biochemical Composition Of Turbinid Snails And Its Sensitivity To Ocean Climate Change, Roslizawati Ab Lah Jan 2017

Biochemical Composition Of Turbinid Snails And Its Sensitivity To Ocean Climate Change, Roslizawati Ab Lah

Theses

Information on the biochemical composition of under-utilised species, such as turban snails, is required to establish their nutritional quality, and improve consumer acceptance as a novel food source. Turbo militaris, Lunella undulata and L. torquata are large common gastropod species with overlapping distributions in eastern Australia. The edible foot tissue from these three species was analysed for comparison of their proximate composition, fatty acids and mineral elements. All species were found to have a high protein content and low lipid levels that are rich in polyunsaturated fatty acids (PUFAs), with a favourable ratio of omega–3/omega–6 PUFAs for ...


Behavioural And Biochemical Responses To Dietary Mercury Exposure In Two Commercially Important Marine Species, Cyntia Ayumi Yokota Harayashiki Jan 2017

Behavioural And Biochemical Responses To Dietary Mercury Exposure In Two Commercially Important Marine Species, Cyntia Ayumi Yokota Harayashiki

Theses

Mercury is a toxic metal with a global distribution. Studies on waterborne exposure to inorganic mercury in aquatic organisms showed changes in biochemical markers and behaviour. Few studies have focused on the effects of inorganic mercury ingestion. This thesis investigated dietary exposure of mercuric chloride to post-larvae and juveniles of Penaeus monodon and juvenile Acanthopagrus australis and showed that biochemical marker response depends on the organism, age (post-larvae or juvenile), tissue analysed (e.g. muscle and neurologic tissue) and exposure period (up to 16 days). Additionally, swimming behaviour was a sensitive parameter for post-larvae prawn studies, but not for juvenile ...


Evaluation Of Reproductive Strategies In Captive California Yellowtail (Seriola Dorsalis) Using Genetic Parentage Analyses, Elizabeth K. Smith, Mark Drawbridge Ms, John Hyde Phd, Geoffrey Morse Phd Sep 2015

Evaluation Of Reproductive Strategies In Captive California Yellowtail (Seriola Dorsalis) Using Genetic Parentage Analyses, Elizabeth K. Smith, Mark Drawbridge Ms, John Hyde Phd, Geoffrey Morse Phd

Theses

A good understanding of spawning dynamics of species in aquaculture is vital in order to maximize egg production and quality as well as efficient allocation of food and space resources. The breeding program of California yellowtail (CYT; Seriola dorsalis previously Seriola lalandi) at Hubbs-SeaWorld Research Institute (HSWRI) is set up such that up to 30 wild caught brood fish can broadcast spawn in a group setting, just as CYT reproduce in the wild. The population of brood fish were originally caught offshore from Southern California, and are maintained under ambient sea water and natural lighting conditions. The spawning season at ...


Biological And Physiological Condition Of Juvenile California Halibut (Paralichthys Californicus) Exposed To A Contamination Gradient In Mission Bay, Ca, Kevin Stolzenbach Dec 2014

Biological And Physiological Condition Of Juvenile California Halibut (Paralichthys Californicus) Exposed To A Contamination Gradient In Mission Bay, Ca, Kevin Stolzenbach

Theses

Contaminated sediments in marine environments have been shown to be good indicators of ecological risk and a means to assess anthropogenic impacts on marine habitats and the animals that inhabit them (Long et al. 1995, Rattner 2009). Estuarine sediments are especially complex media with regard to physical, chemical, and biological characteristics that trap, store, modify and sometimes release contaminants to the biota (Long et al. 1995). Especially vulnerable are animals that are in constant contact with the sediments, such as flatfishes that partially bury themselves for camouflage (Costa et al. 2011). Impacts can be assessed in a number of ways ...
