Large trap nets were evaluated as a commercial gear for capturing buffalo fish during July-September 1965. During the 72-day bigmouth buffalo dominated the catch (78.2% by weight). Eight sport species accounted for 3.6% of the total catch. Both 7.0-cm and 12.7-cm mesh (extended measure) were used in the back of the bailing crib of the nets to determine the effect of the 12.7-cm mesh in reducing the catch of sport species and nonmarketable size groups of commercial species.

Twenty-seven fish species were captured in Lake Oahe with trap nets in 1963-67. The catch was dominated by eight species in order of abundance: black crappie, bigmouth buffalo, white crappie, carp, river carpsucker, freshwater drum, smallmouth buffalo, and goldeye. Catch per unit of effort did not reflect changes in abundance of some of the species because of variation in environmental conditions. Frequency and strength of postimpoundment year classes were considered the best indicators of the ability of a species to adapt to reservoir conditions.

As we begin the third decade of the twenty-first century, women have entered the workplace in unprecedented numbers, are now outperforming men in terms of educational qualifications, and are excelling across a range of professional fields. Yet men continue to occupy the positions of real power in large corporations. This book draws on unique, unprecedented access to Chairs of FTSE 350 Chairs, boardroom aspirants and executive head-hunters, to explain why this is the case. The analysis it presents establishes that the relative absence of women in boardroom roles is not explained by their lack of relevant skills, experience or ambition, but instead by their exclusion from the powerful male-dominated networks of key organisational decision-makers. It is from within these networks that candidates are sourced, endorsed, sponsored, and championed. Yet women’s efforts to penetrate these networks are instead likely to trap them into network relationships that will be of little value in helping them to fulfil their career aspirations. The analysis also identifies why women struggle to gain access to these networks, and in doing so, it demonstrates that the network trap in which women find themselves will not be overcome simply by encouraging them to change their networking behaviours. Instead, there is a need for a fundamental reconsideration of how boardroom recruitment and selection is conducted and regulated, to ensure the development of a more open, transparent and equitable process.

The Third Edition of this popular reference work describes the methods and rationale for sampling mosquitoes. Originally written by Professor M. W. Service, the book has been updated by John B Silver. More than 1,000 new references have been added and out-of-date material has been removed. The book emphasizes the ecology and behavior of those species that play a role as vectors of human and animal diseases and infections. Designed to serve as a practical reference for field entomologists and mosquito control specialists, it describes sampling methods and trapping technologies and tools for the collection of mosquitoes from egg to adult.
