The FAO Fishery Committee for the Eastern Central A"Glantic (CECAF) held its 'I'hix'd Session from 11 to 15 December 1972, at the kind invitation of the Gover:illlleni; of Spsjn 1 a,t the Escue la Oficial de Nautice, at Santa Cruz de Tenerife I Canary Islands. The session was attended by the representatives of 18 nations, members of the Committee, by observers from one nation, and by representatives and observers from four international organizations. A list of par1icipants is given in Appendix A to this report. 2. Mr. D. Layachi {Morocco), elected Chairman at the Second Session of the Committee, was in the Chair at the opening of the session. 3. The Committee was welcomed by Admiral L. Boado Endeiza, Deputy-Secretary of the Merchant Marine. The Chairman of the Committee and Mr. F.E. Popper, Assistant Director­ General (Fisheries), addressed the session. The texts of their addresses are reproduced in Appendices B, c, and D to this repor~. ADOPTION OF THE AGENDA AND ARRANGEMENTS FOR THE SESSION 4. The Committee adopted the Agenda given in Appendix E to this report. The documents which were before the Comrni ttee are listed in Appendix F ·to this report. STATE OF THE STOCKS 5. At its Second Session (Casablanca, May 1971), the Committee had modified the terms of reference of its Working Party on Regulatory Measures for Demersal Stook,g and had renamed it Working Party on Resources Evaluation. The Working Party met in FAO, Rome, in April 1972 under the chairmanship of Mr. E.O. Bayagbona (Nigeria) and its report was made avail­ able to the session (CECAF/72/4). 6. The Committee noted that new data collected since the meeting of the Working Party confirmed the trends already observed. Among the offshore demersal stocks of the northern area, the hake stock remained heavily exploited. The situation was similar for sparids. As far as cephalopods were concerned, there seemed no doubt that both cuttlefish and squid were heavily fished, while an increase in the catch of octopus might still be possible. 7. The Committee took note of the findings of the Working Party regarding the effect of various mesh sizes on catches of ~gellus bellotti and on the st~te of the inshore demersal stocks in the tropical zone. 8. The review of the state of the coastal pelagic resources made by the Working Party was considered by the Committee who was informed that, because of insufficient data1 the Working Party had not been able to assess the potential of the pelagic stocks found in the area between the Spanish Sahara and Guinea. However, preliminary estimatesl/ made since the meeting of the Working Party suggested that in 1972 the stock of round sardinella was being almost fully exploited, the mackerel stock was overfished while the horse-mackerel stock should be able to support a substantial increase of fishing. 9. The Committee discussed at length the difficulties encountered by the Working Party in carrying out its duties. In view of the unavailability or inaccuracy of some statistical and biological data, the Working Party had been unable to assess with precision the state of some stocks and to provide sound advice on regulatory measures suitable for their conser­ vation and management. The Committee recognized that the quality of advice formulated by J. Elwertowski, P. Gonzalez Alberdi, J. Chabanne and T. Boely (1972). PremHre esti­ mation des ressources p~lagiques du plateau continental ouestafricain. Centre de recherches oc~anographiques de Dalcar, Thiaroye. DSP No. 42 - 2 - the Working Party depended to a large extent on data collected and studies carried out by member cotU1tries. In this regard the Committee pointed out that the right to fish common resources carried with it a duty to collect and to make available to bodies responsible for joint appraisal of these resources the statistical and biological data needed for this work. 10. The Committee listed the fields where research should be urgently intensified. Among the first priorities it identified: (a) The refinement of appraisal of coastal pelagic stocks in the northern transitional zone (b) Foreseeable effects of limitation of fishing effort for the most heavily fished stocks (c) Assessment and management studies on inshore demersal stocks in the tropical area (d) Selectivity studies regarding the main demersal species It was emphasized that the Working Party would be able to provide further advice only if member countries supply the data and information needed for these studies. The Committee therefore urged nations fishing in the area to undertake or to intensify their investiga­ tions in those fields. The Committee requested the non-coastal countries to participate particularly actively in the collection of data. 11. With regard to inshore demersal stocks in the tropical zone, the Committee noted that in certain areas info:rmation available was already sufficient to formulate measures limiting mesh size and/or fishing effort. Considering the relative homogeneity of the zone, it should be possible from a review of existing information provided by local laboratories to determine measures applicable to the whole area. The Committee recommended that such analysis be in­ cluded in the agenda of the next meeting of the Working Party. 12. The Committee stressed that inaccuracy or unavailability of data on the stocks does not lessen the urgent need for implementation of regulatory measures. These should be formulated on the best scientific evidence available even though these measures may need to be modified as soon as it became evident that it was beneficial to do so. 13. Some delegations raised the question of fishing pelagic species for fish meal production and recalled the appeal made by the Committee at its Second Session (May 1971) (paragraph 24 of the Report) .Y MESH SIZE REGULATION IN ·!'HE CECAF AREA 14. The report of the First Session of the CECAF Sub-Committee on Implementation of Manage­ ment Measures (CECAF/72/5) was presented. In addition to a general discussion of management problems, the Sub-Committee had formulated a specific recommendation (Appendix D of its report) concerning the introduction of a provisional minimum mesh size of 70 mm for use by vessels fishing for hake or sea bream in the CECAF area. This recommendation was endorsed by the Committee. The Sub-Committee recommendation also called on countries to inform the Director-General of FAO of measures taken by Governments in accordance with the terms of the recommendation. 15. The Secretariat informed the Committee that several countries had already formally notified the Director-General of steps being taken. In addition many delegations informed the Committee that their Governments supported the measures, and to the extent that their nationals were engaged in fishing for hake and sea breams, were taking appropriate action. ',gj FAO Fish.Rep., (107) 1971 16. One country,while ensuring that it was talcing action in accordance with the Sub­ Committee's recommendation, reiterated its belief that it was more appropriate for manage­ ment measures to be implemented by a treaty-based body rather than by FAO or its subsidiary bodies. 17. It was noted that quantities of sea breams were caught in fisheries of other species, in particular shrimp and oephalopods. The Committee considered that it was desirable in principle to limit these incidental catches as far as possible and to reduce the allowable by-catch from 20 percent to 10 percent, if the practical difficulties could be overcome. FAO was requested to circulate information concerning designs of shrimp trawls which mini­ mized the incidental catches of fish and the Sub-Committee was requested to examine, on the basis of scientific data submitted to it, the feasibility of recommending that the percen­ tage of allowable by-catch be reduced from 20 percent to 10 percent.

  • A Study of UK Gaming Attitudes and Behaviours
    Game on: a study of UK gaming attitudes and behaviours How smartphones, esports and VR are changing the way we play savanta.com savanta.com Contents 3 Introduction 4 Industry overview: who are gamers? 12 The four gamer personas 18 Gaming purchasing behaviour and spend 22 Addiction and bullying: the dark side of gaming 26 Who watches esports? 29 VR: what does the future hold? 32 Conclusion 33 How Savanta can help you savanta.com 2 Introduction Much has changed in the gaming industry since the days of Pong and Pacman or even Mario and Sonic; now everyone with a smartphone has access to a world of games in their pocket. More than two thirds (67%) of people in the UK have played a game on a smartphone over the past year. The ways in which people buy video games have also evolved with more than a third (36%) of gamers saying they have purchased a gaming subscription and 30% using a game key or token within the last three months. Gaming is no longer a niche pastime. Overall, the majority (86%) of the UK population have played a game of some kind over the past year, and although 17% of Brits agree with the statement that “most gamers are kids or teenagers” the data demonstrates that this is categorically untrue. This report on the gaming industry sets out to debunk some myths as well as looking at the personas of different gamers, their gaming habits and their views on emerging trends such as esports and the future of virtual reality.

    Resources, Conservation and Recycling, 6 ( 1992 ) 243-257 243 Elsevier Science Publishers B.V. Composting of domestic refuse and sewage sludge. II. Evolution of carbon and some "humification" indexes Emeterio Iglesias Jim6nez and Victor P6rez Garcia Instituto de Productos Naturales y Agrobiologia de Canarias, Tenerife, Canary Islands, Spain (Received 15 July 1991; accepted in revised form 6 January 1992 ) ABSTRACT Iglesias Jim6nez, E. and P6rez Garcia, V., 1992. Composting of domestic refuse and sewage sludge. II. Evolution of carbon and some "humification" indexes. Resour. Conserv. RecycL, 6: 243-257. The evolution, during composting of city refuse (R-pile) and city refuse + sewage sludge co-com- posting (R + S-pile), of total organic matter (TOM) and some forms of carbon: total organic carbon (Ct), oxidizable carbon (Co), alkaline-extractable carbon (Cox), humic acid-like carbon (Cha), and fulvic acid-like carbon (Cfa), was evaluated. The results were correlated with some maturity param- eters, namely, C/N ratio in the solid phase (C/Ns), C/N ratio in the water-soluble phase (C/Nw), and cation-exchange capacity (CEC), to examine the relationships between the mineralizationof the organic matter, biological stability of compost, and "humification". The regression analysis was carried out consideringjointly all the data points of both the R-pile and the R + S-pile, to extrapolate new maturity criteria irrespective of the initial composition of the urban raw material used for composting. The results show that the CEC/Ct and ChJCfa ratios may also be considered to be good maturity parameters. A value higher than 1.9 for both ratios, in addition to a value lower than 6 for the C/Nw ratio, may be considered as a suitable indicator of a high degree of maturity in composts of urban origin (municipal solid waste and sewage sludge composts).

  • Selecting the Optimal Resins for Removal of DNA Contamination During Process Purification
    Practical Guide: Selecting the Optimal Resins for Removal of DNA Contamination during Process Purification Payal Khandelwal, PhD Bio-Rad Laboratories, Inc., 6000 James Watson Drive, Hercules, CA 94547 Purification Solutions Bulletin 6881 Effectively Eliminate DNA Contamination with Our Versatile Process Resins Cell culture production of recombinant proteins invariably results in a protein sample contaminated with host cell DNA. The contaminating DNA leads to increased viscosity of the feedstream and can interfere with subsequent purification steps such as anion exchange chromatography. In addition, contamination with cellular DNA creates a therapeutic risk. Regulatory authorities require that DNA levels in all therapeutic protein and antibody samples be reduced to 10–100 pg/dose. Cell culture clarification processes, such as centrifugation or tangential flow filtration (TFF), can provide some initial DNA removal. However, such techniques create high-shear conditions, which could increase cell disruption and, as a result, contamination. In addition, use of Benzonase or other nucleases can lead to contamination with DNA fragments instead of the full-length DNA and requires subsequent nuclease removal. Moreover, this method does not maintain the DNA binding activity of some proteins, which can be a requirement of the purification process. In contrast, chromatography avoids these issues, resulting in improved DNA removal from process streams. Bio-Rad has provided a progressive selection of chromatography resins for the process-scale purification
