Viktor Lewynsky has over 44 years of experience in fisheries management, aquatic ecology, statistics, and environmental management in Canada and the US. He has held positions with various government agencies and research organizations, focusing on areas such as fisheries surveys, population dynamics, habitat evaluations, and environmental training. He now works independently as a fisheries consultant through his own company, providing professional services to government, industry, First Nations, and other groups.
Catch Per Unit Effort (CPUE) of Bivalves in Northwestern Bohol, PhilippinesAI Publications
Catch Per Unit Effort (CPUE) is a measure of status of marine resource in a given area. In this study, bivalve fishery information was gathered using the self-structured questionnaire. There were 61 respondents who were the registered fishermen of Calape, Tubigon and Clarin. Among the three towns it was Clarin where highest mean CPUE was observed with 1.2kg/hr/man. This was followed by Calape with 0.8kg/hr/man and lowest mean CPUE was recorded in Tubigon with 0.6kg/hr/man. High CPUE value means that there are still enough bivalve resources in the area and lowest CPUE means that these resources are endangered. Considering that, the result of this study showed that there is a need to regulate the collection of bivalves with lower wild stocks to avoid loss of these natural resources.
Aspects of life-history strategy of Marcusenius senegalensis (Pisces: Osteogl...AI Publications
Marcusenius senegalensis (Steindachner, 1870) is the dominant mormyrid in Niger River in Northern-Benin where this fish species constitutes an important component of artisanal fisheries. The current study documented the reproductive biology of M. senegalensis in order to contribute to management and sustainable exploitation. Monthly samplings were conducted between February 2015 and July 2016 using gillnets, cast net, and seine. Males dominated the population with a sex ratio of 1:0.96 in favor of males. Sizes at first sexual maturity were 167.89 mm-TL for males and 163.81 mm-TL for females. Monthly gonadosomatic index (GSI) averaged 0.12 ± 0.09 for males and 1.32 ± 1.56 for female and peaks recorded indicated that spawning occured from June to September. Fecundity were moderate to low (844 – 12,643 eggs) and significantly (p < 0.05) increased with total length and body weight. Thespecies showed egg diameters varying between 0.21 and to 1.77 mm and ovaries comprised oocytes at all stages of maturation indicating that M. senegalensis displayed a multi-spawning behavior. Marcuseniussenegalensis exhibited a demographic strategy between r and K, yet more inclined towards K-selected strategy. In Niger River, reproduction grounds were being severely degraded affecting recruitment and stocks. The current findings are valuable data to design a species management scheme that should includes spawning ground protection, species conservation and valorization and fisheries/aquaculture development.

C2.02: Informing Priorities for Biological and Ecosystem Observations, suppor...Blue Planet Symposium
There are increasing opportunities to expand observation of ocean biology from advances in individual sensors to development of national and global networks. To leverage these opportunities, the ocean community has defined essential variables, initially in physical oceanography. In 2013, a Biological Integration and Observation Task Team (BIO-TT) was formed under the IOOC to focus on biological essential variables for U.S. IOOS. The primary goals of the BIO-TT were a) to improve availability of observations on the existing IOOS core biological variables (defined by BIO-TT as phytoplankton species; zooplankton species and abundance; fish species and abundance), and b) to identify and prioritize additional cross-cutting federal agency biological and ecosystem observation needs.
To address these objectives the team (1) completed a survey of federal agencies for existing core variable datasets and identified needs for biological and ecosystem observations and (2) conducted an expert workshop to explore best available science of biological and ecosystem observing, and determine implementation strategies for biological and ecosystem observation needs identified from the survey. To build upon the actions and recommendations made previously by several other groups working towards the development of a global, coordinated ocean observation system, the BIO-TT Expert Working Group activities followed the guidelines developed by the Framework for Ocean Observation (2012) and the prioritization themes identified by the GOOS Biology and Ecosystems Panel (IOC 2014).
Workshop participants agreed that the highest priority is to include species and abundance of core functional groups (pelagic and benthic) not currently represented among the IOOS core variables. This presentation will summarize key results from the survey and then focus on analyses, outcomes and recommendations from the expert workshop for new and enhanced biological variables as part of IOOS.

Experience Summary
Vic Lewynsky has 44 years technical and professional experiencein aquatic ecology,
fisheries management, statistical methods,forestry, and general environmental
management in Canada and the USA.
Mr. Lewynsky’s experience in aquatic resourcemanagement extends from
limnological methods to commercial and recreational fisheries management. At
Simon Fraser University,Vic conducted a variety of aquatic surveys and research,and
instructed laboratory courses in limnology. His research activities with the Idaho
Cooperative Fishery Research Unit focused on: the use and effect of regulations in
sportfishery management; creel survey methodologies; movements and seasonal
distribution of trout; age-and-growth analysis;and population dynamicsof exploited
trout stocks.
Vic joined B.C. Hydro to assist their Transmission,Distribution and Generation
Divisionsdevelop and implement their initial environmentmanagement program for
their field operations.This subsequently included environmental services for
Transmission and Distribution development and maintenance activities and
generation and reservoir operations throughout the Northern and Southern Regions
of British Columbia. He also conducted environmental trainingneeds-assessments
among the wide range of employee disciplines,staff and contractors,and helped
develop and deliver specialized environmental trainingmodules.Vic was periodically
seconded to assistFirstNations in their fishery monitoringprograms in south central
BC and help finalizeFish-and-WildlifeCompensation Agreements with the Provinceof
B.C. stemming from reservoir and hydro generation development in the Columbia
River basin.
As principal of Western Renewable Resources,Vic provided professional services to
federal and provincial governments, industry (fishing,forest,utility and agricultural),
FirstNations and privateconcerns. Services provided include: general project
administration and management, fisheries feasibility studies and management
planning,fish harvestsurvey designs and analytical counsel, numerous studies on
steelhead trout harvestby commercial and FirstNations fisheries,sportfishery
evaluations,fisheries exploitation/habitatevaluations,ageand growth analysisof
resident and anadromous fish populations,timber harvestingcounsel on private
lands,silviculturesurveys,stand tending, data management and processing,
data/statistical analyses and ghost-writing technical reports.
Vic’s formal trainingin applied statisticsincludes:graduatecourses in survey
sampling,experimental design, parametric and nonparametric methods, multivariate
analysisand mathematical ecology. This is supported by a useableknowledge of
several statistical softwareprograms. His formal analytical background is
complemented with direct field experience in designingand managing creel surveys
(fish harvestand user profiles),harvestsurveys of commercial and First-Nation
fisheries,experimental designs, fish population and habitatsurveys and timber
cruising.

Furthermore, Mr. Lewynsky has a sound knowledge of forestry operations.His
involvement with forest resources extends from actual timber harvestingto forest
protection. Work performed duringemployment with industry and government and
personal enterprise(Small Business foresttenure harvesting) include:
Road location,cut-block layout,timber cruising;
Timber saleplanningand contractsupervision;
Firesuppression organization and supervision; and
Road, landingand skid-trail construction,timber fallingand skidding.
Vic’s interdisciplinary education and experiencefrom layman to professional in
fisheries and forestry has provided him with the ability to communicate effectively
with a wide cross-section of the scientific community,resourceusers,employees,
managers, executives and the general public.
