Development of a hydrodynamic model to investigate near field and regional connectivity around Okehampton Bay

Project number: 2018-119
Project Status:

Need

Primarily this project is needed to satisfy the regulatory requirements of the Tasmanian salmon industry regulator, the EPA. Currently there is no calibrated local scale model that is suitable to provide connectivity information of the region in question. This proposal aims to develop a nested suite that may provide environmental information to assist in satisfying the salmon farming requirements in the region.

Objectives

1. A calibrated model is developed, where the model skill is known and those connectivity characteristics can be bounded by levels of confidence.

Summary

The study aims to satisfy the regulatory requirements of Environmental Licence 10172/2 from the Tasmanian EPA around Tassal’s use of Okehampton Bay for salmonoid aquaculture, particularly the possible fate of material released within Okehampton Bay into the receiving environment. To achieve that objective, the CSIRO Coastal Environment Modelling team (CEM team) developed a hydrodynamic model to investigate the far field and regional hydrodynamic connectivity around Okehampton Bay and the Mercury Passage surrounds, hereafter referred to as the OKE model.

Development and test-marketing of value-added tuna products

Need

From a number meetings with both Woolworths and Coles supermarkets we have found strong demand for our intended retail range of products namely:
1.Albacore tuna hot smoked
2.Yellowfin tuna cold smoked
3.Yellowfin tuna steaks 4 marinated flavours - natural, asian, thai chilli and indian (single serve)
4.As above in double serve
5.Atlantic salmon steaks in 4 marinated flavours natural, asian, thai chilli and apricot.

Both supermarket chains are keen to see the products trialled in each of ten stores in NSW over thirteen weeks. To enable us to meet this demand we are seeking NSC support for the following areas.

1.Determination of shelf life and maximising this shelf life to at least 14 days for selected marinated products. To assist in achieving this a new chemical sanitising agent for direct contact use will be investigated to quantify benefit to shelf life. This chemical will be most likely classified as a processing aid as it is non toxic already approved by The National Health and Medical Research Council NHMRC. Approval is being sought from the ANZFA by the chemical supplier and will be obtained before product launch.

2.Development of a documented HACCP based food safety plan for the processing of the range of Smokin Joes products. This will require consultant input and involve overall audit for the processing area, necessary and appropriate staff training and system documentation.

3.Offset of the cost of production to retail test market stage specifically - the cost of supply and printing of laminate vacuum pouches. The printing is quite expensive involving each of five different product labels being printed directly onto each of the bags. To minimise costs hand stuck flavour labels will be applied to each product. Normally the minimum print run is 20,000 for each product although 10,000 can be obtained at a dearer rate. This operating expense (additional to all the others involved) is more than we can beet at this time. We are meeting new capital equipment costs of $17,000 and other operating costs of well over $100,000 during the course of the test market phase. The packaging is vital to the success of the product as beyond being functional it must assist to influence the customer to purchase.

We have obtained a range of quotes for the packaging and the best is listed below:

Packaging price supplied and printed per 1,000/20,000per 1,000/10,000
smoked albacore tuna $208.82 $313.64
smoked yellowfin tuna $274.87 $375.58
yellowfin tuna steaks (single serve)$220.45 $327.55
yellowfin tuna steaks (twin serve)$227.33 $334.87
tasmanian atlantic salmon steaks$75.00 $120.00
total per 1,000 $1,226.92 $1799.19

Objectives

1. Determine the potential retail shelf life for selected marinated tuna and salmon products or other species such as spotted trevalla, including the trial of a commercial sanitizer on the fish during processing
2. Document a HACCP food safety plan for Smokin Joe's products
3. Document as a case study, the degree of market acceptance achieved during the test marketing phase - indicating sale performance variability between stores, between products and variation over time eg repeat sales and any customer feedback mechanism employed
4. Produce a report to NSC on the above three activities

TSGA IPA: Understanding Dorvilleid ecology in Macquarie Harbour and their response to organic enrichment

Need

Previous research has shown a clear impact gradient associated with cage salmon farming operations, and that presence of bacterial mats (Beggiatoa) and proliferation of opportunistic species are features commonly associated with high levels of organic enrichment (e.g. Pearson & Rosenberg, 1978). The presence of opportunists, such as Capitellid worms, being classified as representative of “unacceptable impact” (Macleod et al., 2004). This premise has been validated in SE Tasmania and underpins regulatory monitoring requirements statewide (DPIPWE, 2004).

The understanding that proliferation of opportunists represents deteriorating conditions was translated to monitoring protocols in Macquarie Harbour, but the relationship between opportunists and the level of enrichment was not explicitly tested in this region. However, video surveys suggest that in Dorvilleid worms rather than Capitellids were the species most indicative of organic enrichment effects(DPIPWE, 2004). Dorvilleids can tolerate anaerobic sediments and high levels of hydrogen sulphide (Levin et al. 2013) and are known to be indicators of the impacts of finfish aquaculture (e.g. Paxton et al. 2010).

However, Macquarie Harbour is ecologically very different to other farming areas in SE Tasmania; the sediments are inherently depauperate, largely epibiotic and spatially patchy. A recent study in Canada has highlighted the need to better understand the relationships and compliance thresholds for established enrichment indicators (i.e. Beggiatoa sp and opportunistic polychaete complexes) in systems where ecological patchiness may occur (Hamoutene et al 2014); suggesting that, where there is significant potential for small scale spatial variability, normal successional responses may not be as reliable. Consequently, the responses may not be consistent with expectations developed from southern Tasmanian regions.

In this context it is important to identify the relationship between Dorvilleids and sediment condition; determining the reliability of this species as an indicator of sediment condition, and characterising the environmental conditions associated with changes in Dorvilleid abundance.

Objectives

1. Review the international literature to establish the current state of knowledge regarding Dorvilleid ecology, and in particular, their response to organic enrichment. This will include a review of their current use as indicator of the impacts of finfish aquaculture.
2. Carry out targeted field survey at selected leases to identify the relationship between Dorvilleids and sediment condition, characterising the environmental conditions associated with changes in Dorvilleid abundance.
3. Based on the finding of 1. and 2. determine the reliability of this species as an indicator of sediment condition in Macquarie Harbour
4. In conjunction with industry and government stakeholders make recommendations on the future use of Dorvilleids in regulatory monitoring of Salmonid aquaculture in Macquarie Harbour
