Annual Report|2016 2 Crisp Annual Report 2016 ANNUAL REPORT|2016 2 CRISP ANNUAL REPORT 2016 1 SUMMARY CRISP, the Centre for Research-based Innovation in Sustainable fish capture and Processing technology, started its research activities in April 2011. Since its launch, the consortium has consisted of four industry partners (Kongsberg Maritime AS, Simrad; Scantrol Deep Vision AS; the Egersund Group AS; Nergård Havfiske AS), four research partners (the Institute of Marine Research; Nofima AS; the University of Bergen; the University of Tromsø), and two sponsors (Norges Råfisklag; Norges Sildesalgslag).

This faculty enjoyed full acauemic rights and existed in Olsztyn until 1968 when it was reorganized according to directions of current scientifical development and needs of the country, :uid transferred to the University of Agriculture in Szczecin where it was given the name of the Faculty of Marine Fisheries. It grew up withinthe structure of this institution, dealing mainly with problems of marine fisheries as well as processing andpreservation of marinefoods, and acquired its present namein 1976. The Faculty enioys full academic rights in providing fishery oriented education up to M.Sc. level and in conferri.11g doctoral degreesin relevant fields. The Faculty includes 14 professors, 45 Ph.D. - and D.Sc.-holders, 38 M.Sc.-holders, technical personnel, and foreign language teachers. To date, more than 2200 students have graduated from the Faculty, among them 62 students from foreign countries, from Asia, Central and South America, and South-EasternEur ope. During its 34-year-long history the institution has contributed considerably to the exploitation of the sea and inland waters, mainly by: educating highly qualified spe<:ialists, conducting research works, cooperation infisheries with internationalorganizations, organizinginternational sy mposia and conferences.

  • Fish Wheels Lawrence Hall of Science
    Fish Wheels Lawrence Hall of Science This activity outline was developed for use in a variety of informal venues. By design, it provides the content, pedagogy and strategy necessary for implementation by both the novice and experienced informal educator. It is expected that this outline will be adapted and improved upon by the user. We welcome your feedback! Synopsis of the Activity Learners make fish adaptations wheels that allow them to examine different body structures (mouth shape/position/teeth, body shape, tail shape, and coloration patterns) and how their variations allow fish to be successful in their habitats. Based on this information, learners make predictions about the behavior and habitats of fish throughout the aquarium. Audience This activity is meant for a general audience. Younger learners will need some help putting together their fish wheels. Setting This activity can be set up in front of any size tank in an aquarium and then visitors can continue to make observations throughout the aquarium. Activity Goals • To engage the learner to think about the organism as if they were a biologist studying it. • To engage visitors to interact with aquarium exhibits. • To encourage learners to actively observe fish in aquariums and to make explanations based on evidence. • And through observations of body structure and coloration, draw some conclusions about the fish’s behavior and habitat (especially its movement, what it eats, strategies for defense, and where it lives in the water column). Concepts • Investigating the observable structures and behaviors of fish can provide a lot of information about how the fish lives and moves in its habitat.

  • Species Composition and Diversity of Fishes in the South China Sea, Area I: Gulf of Thailand and East Coast of Peninsular Malaysia
    S4/FB3<CHAVALIT> Species composition and Diversity of Fishes in the South China Sea, Area I: Gulf of Thailand and East Coast of Peninsular Malaysia Chavalit Vidthayanon Department of Fisheries, Bangkok 10900, Thailand ABSTRACT The collaborative research on species composition and diversity of fishes in the Gulf of Thai- land and eastern Malay Peninsula was carried out by R. V. Pramong 4 in Thai waters and K.K. Manchong, K.K. Mersuji in Malaysian waters, through otter-board trawling surveys. Taxonomic surveys also done for commercial fishes in the markets of some localities. Totally 300 species from 18 orders and 89 families were obtained. Their diversity are drastically declined, compare to the previous survey from 380 species trawled. The station point of off Ko Chang, eastern Gulf of Thai- land and off Pahang River shown significantly high diversity of fishes57 and 73 species found. De- mersal species form the main composition of the catchs. The lizardfish Saurida undosquamis, S. miropectoralis, the bigeye Priacanthus tayenus and P. macracanthus, the rabbitfish Siganus canaliculatus and hairtail Trichiurus lepturus were the most abundant economic species found in mast of the sampling stations. Fishing efforts were 34 hours and 49 hours for the cruises I and II, with average catch per hour of 12.04 and 34.79 kg. respectively. The maximum catch per hour was 175.3 kg in Malaysian waters, the minimum was 4.33 kg in Thai waters. The average percentage of eco- nomic fishes is higher than that of trash fishes in Malaysian waters, it ranged from 55.45 to 81.92 %.

Trinh1, Kristian Muri Knausg˚ard2( ), Arne Wiklund1, Tonje Knutsen Sørdalen3;4, Alf Ring Kleiven3, Lei Jiao1, and Morten Goodwin1 1 Centre for Artificial Intelligence Research, University of Agder, 4879, Grimstad, Norway 2 Department of Engineering Sciences, University of Agder 3 Institute of Marine Research (IMR), His, Norway 4 Department of Natural Sciences, Centre for Coastal Research (CCR) University of Agder, Kristiansand, Norway [email protected] Abstract. Our understanding and ability to effectively monitor and manage coastal ecosystems are severely limited by observation methods. Automatic recognition of species in natural environment is a promising tool which would revolutionize video and image analysis for a wide range of applications in marine ecology. However, classifying fish from images captured by underwater cameras is in general very challenging due to noise and illumination variations in water. Previous classification meth- ods in the literature relies on filtering the images to separate the fish from the background or sharpening the images by removing background noise. This pre-filtering process may negatively impact the classification accu- racy. In this work, we propose a Convolutional Neural Network (CNN) using the Squeeze-and-Excitation (SE) architecture for classifying im- ages of fish without pre-filtering. Different from conventional schemes, this scheme is divided into two steps. The first step is to train the fish classifier via a public data set, i.e., Fish4Knowledge, without using im- age augmentation, named as pre-training. The second step is to train the classifier based on a new data set consisting of species that we are arXiv:1904.02768v1 [cs.CV] 4 Apr 2019 interested in for classification, named as post-training.
