The protein requirement of juvenile silver trevally (Pseudocaranx georgianus) to optimise growth in hatchery environments : a thesis presented in partial fulfilment of the requirements for the degree of Master of Science in Animal Science at Massey University, Manawatu, New Zealand
Figures 2-4 (p. 10), 2-5 (p. 15) & 2-6 (p. 21) were removed for copyright reasons.Aquaculture is a growing primary industry in New Zealand. Currently the industry is comprised
of three main species: GreenshellTM mussels, Pacific oyster, and King Salmon. The introduction
of a white fleshed fish presents obvious commercial opportunity and production gains for New
Zealand aquaculture. Silver trevally provides this opportunity and has the potential to further
develop the industry. When developing a new species for aquaculture an understanding of their
nutritional requirements at the different life stages is required. This thesis investigates the
protein requirement of juvenile silver trevally.
Silver trevally (67.5±12.0g) were randomly assigned to 12 tanks, 15 fish per tank. Four isoenergetic
diets ranging in crude protein (CP) content from 30 to 60% CP were fed, in triplicates,
for 12 weeks. Growth, including specific growth rate (SGR), did not significantly differ between
diets. Feed efficiency was lowest in fish fed the 40% CP diet compared with the other three diets.
Protein retention was highest in fish fed the lowest protein diet. Condition indices in silver
trevally were unaffected by the protein content of the diet. Overall, this experiment was
inconclusive on the ideal protein level in the diet.
A palatability trial was carried out to determine if feed intake varied among diets. For
comparison a commercial pellet from Ridley’s (50% CP) and a gel diet (20.4% CP) used by Plant
& Food Research was also included in this trial. Twenty-four fish from the growth trial were
allocated to two tanks for the palatability trial. Four behavioural responses were observed: the
food item was ignored; fish approached the food but did not ingest; the fish took the food into
their mouths before spitting it out; and the food was ingested. The 60% CP experimental diet, a
commercial pellet, and a gel diet had significantly higher rates of intake than the other diets,
with the 30% CP diet having the lowest rate of complete ingestion. The 60% CP and gel diet had
the lowest rate of food being ignored. The most palatable diets were the 60% CP diet and the
gel diet

Public private leasing arrangements: an effective response to the rapid growth in rent supplement claims?
In 2004 a public private leasing arrangement, the Rental accommodation Scheme, was introduced into the housing system of the Republic of Ireland. Lauded as a more structured, accommodation-based approach to the use of the private rented sector to meet long-term housing need, the Scheme was designed as a means of eliminating dependence on temporary income support payments. However over the last ten years expenditure on the rent supplement scheme has increased fivefold while long term dependency on temporary income supports remains an acute housing policy concern. As a result the effectiveness of the Rental Accommodation Scheme has come in for robust criticism. Yet while the Scheme has encountered a number of operational difficulties the Irish Government remains committed to hybrid leasing arrangements as a long term policy instrument. This paper considers the extent to which this hybrid leasing arrangement offers an effective and sustainable housing policy intervention, particularly in light of the onset of the economic recession. The paper begins by explaining the position the Rental Accommodation Scheme within the broader Irish housing system before describing the Scheme’s design and structure. The paper goes on to examine the various difficulties which the scheme has encountered to date before considering the role which regulatory oversight of the hybrid scheme as set out in the Residential Tenancies Act 2004 may play in the coming years
The Wider Context: The Future of Capital Markets Regulation in Developed Markets
At a time of such great turbulence, looking to the future directions of capital markets and their regulation in developed economies is a particularly risky business. We are in the midst of a great sea change. Nevertheless, there are several current, and readily observable, phenomena which are likely to shape capital markets regulation in the near future. First of all, the blurring of the distinctions between developed and developing markets themselves, as well as that between domestic and international markets, has put into question the adequacy of existing regulatory frameworks. Also, the transatlantic dialogue, London – New York, has given way to the rise of “multipolarity”; in an age of instantaneous transmission of information, capital and risk, competing centres of gravity have emerged. In addition, centuries-old market institutions are undergoing a period of dynamic change, producing the equivalent of regulatory jetlag. Among international actors, there are calls for what may be the somewhat indiscriminate widening of the “perimeter” of regulation; costs of compliance mount, regulatory uncertainty sets in. To the numerous, conflicting and perhaps unrealisable, goals associated with capital markets regulation has been added detection and prevention of systemic risk. The two great, albeit quite different, capital market regulatory models (those of the United States and the United Kingdom) have taken a beating; it is an open question as to what will take their place. Finally, in face of the virtually insurmountable difficulties of actually creating a World Financial Regulator (to say nothing of its desirability), two organisations, one created in direct response to the Global Financial Crisis, and the other, decades-old, are filling the void. None of these factors operates independently, of course; all interact, contributing to the potential uncertainty and complexity of outcomes
A Modern Polytheism? Nietzsche and James
Polytheism is a strange view to hold in modernity. Connected as it is in the popular imagination with archaic, animistic, magical, prescientific systems of thought, we don’t hesitate much before casting it into the dustbin of history. Even if we are not monotheists, we are likely to think of monotheism as the obviously more plausible position. The traditional arguments for the existence of God, which have been enormously influential in Western philosophy of religion, do not necessarily rule out polytheism but they are clearly formulated with monotheism in mind. While there could be multiple first causes, intelligent designers, or beings than which nothing greater can be conceived, the simplest and most natural..
