Fish biodiversity and inferred abundance in a highly valued coastal temperate environment: the inner Queen Charlotte Sound, New Zealand

Autor: Rodelyn Jaksons, Peter Bell, Peter Jaksons, Denham Cook

Publikováno v: Marine and Freshwater Research. 73:940-953

Context The inner Queen Charlotte Sound–Tōtaranui is a focal and emblematic coastal area in New Zealand that is valued by diverse stakeholders. Fish diversity in the region is not well characterised. Aims This study sought to provide an inventory

Investigating food limitations in wild fisheries: the attendance and growth responses of fish at an anthropogenic feeding station within a temperate estuary

Autor: Denham G. Cook, Alistair Jerrett, Peter Jaksons

Publikováno v: Journal of Fish Biology. 97:465-478

To investigate whether wild fish populations are food limited, this study explored whether the provision of supplementary food had a positive effect on the abundance, condition and growth characteristics of estuarine fish assemblages in New Zealand.

Validation of fish length estimations from a high frequency multi-beam sonar (ARIS) and its utilisation as a field-based measurement technique

Autor: Karen L. Middlemiss, Alistair Jerrett, Peter Jaksons, William Davison, Denham G. Cook

Publikováno v: Fisheries Research. 218:59-68

High frequency multi-beam sonars enable the determination of fish size characteristics and behaviour in highly turbid and low-light conditions when more traditional methods, such as underwater cameras, are unsuitable. We sought to validate this techn

Investigating time and economic costs of botrytis bunch rot sampling using interpolated data

Autor: Kai S.J. Lewis, Adrian G. Hunt, Joanna M. Sharp, G.N. Hill, Peter Jaksons

Publikováno v: New Zealand Plant Protection. 72:166-175

Botrytis cinerea causes botrytis bunch rot (BBR) disease in wine grapes. Small-scale labour-intensive visual disease assessments may not adequately represent an entire vineyard but larger assessments add cost without necessarily improving accuracy or

Genetic diversity and heritability of economically important traits in captive Australasian snapper (Chrysophrys auratus)

Autor: David T. Ashton, Peter A. Ritchie, Maren Wellenreuther, Elena Hilario, Peter Jaksons

Publikováno v: Aquaculture. 505:190-198

Aquaculture is the fastest growing animal production sector in New Zealand but low species diversity is a barrier to long-term growth. Snapper (Chrysophrys auratus) has been identified as a promising candidate for aquaculture development and an initi

Investigating food limitations in wild fisheries: Estuarine fish form dynamic aggregations around a supplementary feeding station and increase localised secondary productivity

Autor: Alistair Jerrett, Maryam Alavi, Peter Jaksons, Denham G. Cook

Publikováno v: Marine Environmental Research. 173:105527

Whether wild fish populations are food limited in some inshore and estuarine marine ecosystems is an area of increasing research and focus. To investigate this phenomenon, the abundance and behaviours of fish in a temperate South Pacific estuary were

Pollen donor effects on the expression of red flesh colour in kiwifruit

Autor: Alan G. Seal, Peter A. McAtee, C. H. Cheng, Peter Jaksons, A. Blackmore

Publikováno v: Acta Horticulturae. :373-380

The choice of pollen donor may sometimes affect fruit characteristics of kiwifruit. In this study, flowers of a red-fleshed kiwifruit selection were hand-pollinated with pollen from males of diploid and tetraploid Actinidia chinensis var. chinensis a

Characterizing hybrid populations of Actinidia arguta var. arguta and related species

Autor: Peter Jaksons, A. J. Currie

Publikováno v: Acta Horticulturae. :573-578

Commercial cultivars from the genus Actinidia are mainly derived from larger fruited species like Actinidia chinensis var. chinensis and A. chinensis var. deliciosa. Small-fruited species such as Actinidia arguta var. arguta have been of interest for
