Catch Statistics

Experimental bottom fishing trials were conducted in the Northwestern Hawaiian Islands where four different hook sizes (Nos. 28, 30, 34, and 38) were fished simultaneously. Within this series the biggest hook is about 71% larger than the smallest hook. Alterations in gear within this range have no substantive effect on the catch of bottom fish. In all cases examined, variation in catch statistics associated with differing replications (days and sites) greatly exceeded any effect attributable to different hook sizes. It is concluded that for medium- and large-sized fish, the catch is reasonably representative of those fish which strike the hooks and that a sigmoid selection curve most accurately describes the selective properties of the gear in this fishery.Key words: gear selection, hook size, bottom fish, replications

A New Species

A new species of the serpulid genus Metavermilia Bush, 1905 and a new record of the genus Omphalopomopsis Saint-Joseph, 1894 are described from deep-sea lava rocks collected from 2,013 m at Cross Seamount, southwest of the Hawaiiarchipelago. Metavermilia zibrowii sp. nov., differs from its congeners mostly by the presence of a simple and concaveoperculum, extent of the thoracic membrane and tube morphology. Omphalopomopsis langerhansii (Marenzeller, 1885)is the type species of the genus and it is only known through its type specimen. This species is characterized by a simpleoperculum with a shallow convex calcareous endplate, cylindrical peduncle, presence of Apomatus chaetae and high num-ber of teeth in the thoracic uncini. This is the first record of this species outside the type locality and both genera are newly recorded for the Hawaiian Islands.

Multiple Agency

Large, regional-scale marine protected areas (MPAs) and MPA networks face different challenges in governance systems than locally managed or community-based MPAs. An emerging theme in large-scale MPA management is the prevalence of governance structures that rely on institutional collaboration, presenting new challenges as agencies with differing mandates and cultures work together to implement ecosystem-based management. We analyzed qualitative interview data to investigate multi-level social interactions and institutional responses to the surprise establishment of the Papahānaumokuākea Marine National Monument (monument) in the northwestern Hawaiian Islands (NWHI). The governance arrangement for the monument represents a new model in US MPA management, requiring two federal agencies and the State of Hawai‘i to collaboratively manage the NWHI. We elucidate the principal barriers to institutional cotrusteeship, characterize institutional transformations that have occurred among the partner agencies in the transition to collaborative management, and evaluate the governance arrangement for the monument as a model for MPAs. The lessons learned from the NWHI governance arrangement are critical as large-scale MPAs requiring multiple-agency management become a prevalent feature on the global seascape.
