Several local groups have come together for this project to addresses water quality concerns in the Gabilan Watershed – also known as the Reclamation Ditch Watershed (Fig. 1.1). These are Moss Landing Marine Laboratories (MLML), the Resource Conservation District of Monterey County (RCDMC), Central Coast Watershed Studies (CCoWS), Return of the Natives (RON), Community Alliance with Family Farmers (CAFF), and Coastal Conservation and Research (CC&R). The primary goal is to reduce non-point source pollution – particularly suspended sediment, nutrients, and pesticides – and thereby improve near-shore coastal waters of Moss Landing Harbor and the Monterey Bay.

In the spring of 2001, NOAA’s National Marine Sanctuary Program (NMSP) and National Centers for Coastal Ocean Science (NCCOS), in consultation with the National Marine Fisheries Service (NMFS), launched a 24-month effort to define and assess biogeographic patterns of selected marine species found within and adjacent to the boundaries of three west coast National Marine Sanctuaries. These sanctuaries, Monterey Bay, Gulf of the Farallones, and Cordell Bank are conducting a joint review process to update sanctuary management plans. The management plans for these sanctuaries have not been updated for over ten years and the status of the natural resources and their management issues in and around the sanctuaries may have changed. In addition, significant accomplishments in research and resource assessments have been made within the region. Thus, it is important to incorporate new and expanding knowledge into the revised management plans for these Sanctuaries.

In 2003, twelve marine protected areas were established in state waters (0-3 nmi) surrounding the Channel Islands. NOAA is considering extending this network (3-6 nmi) into deeper waters of the Channel Islands National Marine Sanctuary (CINMS). In order for effective long-term management of the deep water reserves to occur, a well-structured monitoring program is required to assess effectiveness. The CINMS and the National Marine Sanctuary Program (NMSP) hosted a 2-day workshop in April 2005 to develop a monitoring plan for the proposed federal marine reserves in that sanctuary. Conducted at the University of California at Santa Barbara, participants included scientists from academic, state, federal, and private research institutions. Workshop participants developed project ideas that could answer priority questions posed by the NMSP. This workshop report will be used to develop a monitoring plan for the reserves.

Se realizaron prospecciones estacionales durante 1998–1999 en Baja California, Baja California Sur, Sonora y Sinaloa para determinar la dimensión y las actividades de las pesquerías artesanales de elasmobranquios dentro del Golfo de California. Ciento cuarenta y siete campamentos o sitios pesqueros fueron documentados, la mayoría de los cuales (n= 83) fueron localizados en Baja California Sur. Entre los campamentos con información pesquera adecuada, la gran mayoría (85.7%) pescaron elasmobranquios en algún momento del año. La mayoría de los pequeños tiburones y rayas demersales fueron capturados en pesquerías multiespecíficas, las cuales también tienen como objetivo teleósteos, pero los grandes tiburones fueron capturados generalmente por pesquerías de redes agalleras a la deriva dirigidas a ellos, o en menor grado, por pesquerías de palangre de superficie. Los pescadores artesanales presentaron un comportamiento altamente oportunístico y temporalmente cambiaban de especie objetivo dependiendo de la productividad de los recursos pesqueros locales de especies de escama, invertebrados y elasmobranquios. Las mayores pesquerías de pequeños tiburones (≤1.5 m, “cazón”) se documentaron en Baja California, Sonora, y Sinaloa durante la primavera y adicionalmente durante otoño e invierno en Sonora. Los tiburones del genero Mustelus (Mustelus spp) dominaron los desembarques de cazón en los estados norteños, mientras que los tiburones martillo juveniles (Sphyrna lewini) sostuvieron la pesquería en Sinaloa. Los grandes tiburones (> 1.5 m, “tiburón”) fueron componente menor de las pesquerías artesanales de elasmobranquios en Sonora y Sinaloa, pero comúnmente fueron capturados en verano y principios de otoño en Baja California y Baja California Sur. El tiburón zorro pelágico (Alopias pelagicus) y el tiburón piloto (Carcharhinus falciformis) fueron comúnmente desembarcados en Baja California, mientras que un diverso ensamble de tiburones pelágicos y grandes costeros fueron observados en los desembarques de Baja California Sur. Las rayas dominaron los desembarques en verano en Baja California y Sinaloa, sostenidas principalmente por elevadas tasas de captura de la guitarra común (Rhinobatos productus, 13.2 individuos/embarcación/viaje) y del tecolote (Rhinoptera steindachneri, 11.1 individuos/embarcación/viaje). La pesquería de rayas de Sonora fue la más extensamente documentada durante este estudio y las rayas (especialmente R. productus) dominaron los desembarques en primavera y verano en este estado. Las tasas de captura estacionales de pequeños tiburones demersales y rayas fueron considerablemente mayores en Sonora que en los otros estados prospectados. Numerosas poblaciones de tiburón (p. ej. C. leucas, C. limbatus, C. obscurus, Galeocerdo cuvier) han sido probablemente sobreexplotados, lo que posiblemente este causando un cambio en el esfuerzo hacia las poblaciones de cazón y rayas costeros. Se proponen recomendaciones de manejo, incluyendo conducir análisis demográficos empleando la información de historias de vida disponible, localizando y protegiendo áreas de crianza e implementando temporadas de veda estacional en las áreas de mayor concentración de elasmobranquios (p. ej. alimentación, reproducción). Sin un manejo pesquero efectivo, vigilado, para sostener o reconstruir las poblaciones de elasmobranquios sujetas a explotación comercial dentro del Golfo de California, el colapso de las pesquerías es un evento probable.

In October 2000 the government of Cambodia announced a major change in fisheries management policy. The core elements of the new policy are the reduction of fishing lot concession areas by 56%, the broader participation of fishing communities in the management of fisheries and a focus on the efficient, sustainable and equitable use of the living aquatic resources. To facilitate the establishment and development of the Community Fisheries, support and monitor their activities, the Department of Fisheries was authorized1 to establish a Community Fisheries Development Office (CFDO).

The River Tweed is, in rod-catch terms, the second most important river in Britain for Atlantic salmon, with an annual rod catch of ca.10,000 fish. This article gives an outline of the second edition of the Tweed Fisheries Management Plan, which is defined as "The co-ordination of data collection and analyses with fundamental research into relevant topics to devise management actions that will beneficially affect the future state of fish stocks". Much of the work set down for the present is concerned with setting up recording and measuring systems for fish catches and exploitation rates, and for the operation of monitoring sites for juvenile densities and adult trout and salmon spawning runs. While surveys show the present state of affairs, the collection of records and regular monitoring of sites will mean that in the future, the past will be better known through a longer series of records. Two case histories are described. The first is concerned with setting aims for managing the brown trout of the Tweed and defining the present state of the fishery. The second is an investigation into the spring salmon of the Tweed.

The purpose of this Fisheries Management Plan (FMP) within the Lake Victoria Fisheries Research Project was to sustain the livelihoods of the communities who depend on the fishery resources of the lake and to reduce poverty, food insecurity and unemployment. To achieve this goals, a better management of the resources, which would mobilize and include stakeholders at local, regional, national and international level was believed to be the right strategy for success.

The River Lune was at one time one of the best salmon fisheries in England and Wales with very high catches to both rods and netsmen. During the 1960's, the stock was decimated by the disease Ulcerative Dermal Necrosis which caused a dramatic reduction in catches. Catches have not recovered to pre-disease levels. The target egg deposition rate for the River Lune system which should produce the maximum number of surplus fish returning to the system has been determined at 13.8 million eggs. This will require 4,779 adult salmon to survive to successfully spawn. Under current rates of exploitation, the target egg deposition will occur at a declared rod catch of 1,974 salmon and a net catch of 2,627 salmon. Two automatic fish counters are in operation on the river system. Data from these suggest that, within the measures of compliance, the river has met it's target egg deposition for the last 3 years.
