摘要

The potential impacts of introducing barramundi (Lates calcarifer) for the purpose of recreational fishing into Lake Kununurra, a tropical impoundment in the Kimberley region of Western Australia, are predicted by dietary comparisons with the resident fishes of the lake. Classification of the pooled dietary data identified five major feeding groups based on similarities in food items consumed. There was no significant dietary overlap between L. calcarifer and all species within the lake. The current study demonstrates that adult L. calcarifer fed primarily on teleosts and decopods, and are known to prey on the majority of the fish species found in Lake Kununurra. Although the introduction of L. calcarifer to Lake Kununurra has the potential to influence the resident fish community through competition (for food and habitat) and predation, it is likely that its effects will be minor. However, the lack of any data that would allow estimation of the likely survival of stocked L. calcarifer fry and fingerlings in the reservoir needs to be addressed. Such data are mandatory if a successful fishery is to be developed in the reservoir. 展开▼

1. The SMA -Eden BM3 (EDEN3) is an extension of the Snowy Mountains Hydro Scheme. The purpose of this engineering project is to safeguard regions of south-eastern Australia now, and in the future, from drought and to supply water as climate change impacts. The EDEN3 will supply de-salinated water from the NSW South Coast and pump it up near the Brown Mountain area into the Murrumbidgee River. This water will flow to Lake Burrinjuck and then be piped into Lake George and into the Shoalhaven River. It is designed to provide a secure water supply to the Eden-Monaro area and provide power.

2. MULTI LISTING REAL ESTATE AUSTRALIA (THE SYSTEM) A multiple-listing agreement sees you sign up with a single agent – (Multi Listing Real Estate Australia) but rather than the property being sold by just that agent, the listing is shared with other agents who are members of the multiple-listing network. Those agents can then market it to their databases, with (Multi Listing Real Estate Australia) the agent you sign with and the agent who sells the property sharing the commission. A BONUS incentive commission is applied to the over listing price if the property is sold above the listing price. [P] . 外国专利： AU2020100632A4 . 2020-06-04
