For Fiji and Samoa, tilapia was for human consumption and as potential pig feed (Costa- Pierce, 1998), although in Tonga it became an unsuccessful attempt to control mosquitoes.

The reproductive, survival and growth performance of four tilapia strains in Fiji, namely Oreochromis mossambicus (M), `Israel' Oreochromis niloticus (NI), `Chitralada' O. Fishes of the genera Tilapia and Oreochromis have become established in a variety of niloticus (NC) and Red tilapia hybrid (R) were evaluated in two culture environments habitats on numerous islands of the South Pacific and Micronesia. Reproductive currently used in Fiji (integrated and non-integrated farming) for three generations. Results populations of tilapias can be found in lakes, reservoirs, streams, rivers, mangroves and showed significant differences among strains in all traits. Overall, the M strain had the shallow lagoons. The reasons for the introductions include mosquito control, aquatic weed highest breeding efficiency and average fecundity but the poorest growth rate. The NI control, culture, stock enhancement and accidental release. Consequences of the strain showed the highest survival and a good growth rate but low breeding efficiency and introduction of tilapias have ranged from dramatic improvements of inland fisheries and fecundity. Although the R strain showed a good growth rate in favorable environments, it the significant development of subsistence and commercial aquaculture to detrimental was prone to stress under less optimal conditions and had a relatively low survival rate effects both on indigenous species and on traditional fish culture systems. and only average fecundity. The NC strain showed the best growth rate and feed conversion efficiency, relatively good breeding efficiency but average fecundity and survival. Based on a weighted performance across all traits, the NC strain was identified Culture as the best performing strain in Fijian conditions. Significant genotype-environment interactions estimated during harvest were due to a strong rank interaction in the R strain and also magnitude interactions in the NC and NI strains.

  • Introducing the Face of Fitzroy G
    ANNUAL REPORT NIWA 2013/14 Q Enhancing the benefits of New Zealand’s natural resources Cover Q. How is NIWA translating forecast data generated by its supercomputer FitzRoy into meaningful and relevant weather information for New Zealanders? A. In early 2014, meteorologist and weather communicator Chris Brandolino joined NIWA’s weather and climate team. Chris has wide international experience explaining the weather using a style and language that engages and makes sense to his audience. NIWA’s goal is to greatly improve the relevance of weather information communicated to the New Zealand public, shifting the focus from forecasting weather alone (“expect rain this afternoon”) to forecasting the impacts of weather on lives and livelihoods (“get the washing dry, or fertilise your pasture, this morning”). NIWA has also increased its capacity in other areas of weather communication – including graphics production – to help translate FitzRoy’s sophisticated technical outputs into meaningful public information. Inside Cover Q. How is NIWA helping farmers improve productivity and reduce risk? A. At the 2014 National Fieldays at Mystery Creek, NIWA launched NIWAFarmMet, a new subscription-based, online weather forecasting and information service tailored to New Zealand farmers (read more on page 33 and visit farmmet.niwa.co.nz). NIWAFarmMet is designed to help farmers identify opportunities to carry out key weather-dependent activities like fertilising, irrigating and harvesting, and prepare for potentially damaging weather like high winds, frosts and floods. Its forecasts are highly localised, rather than tailored to an entire region or the nearest big town, and presented in easy-to-interpret graphical form. NIWA staff demonstrated the product to hundreds of farmers at Fieldays, along with other aspects of its growing suite of weather and climate services.
