Fiskbestånd och miljö i hav och sötvatten : Resurs- och miljööversikt 2012
- 2012
-
Rapport (övrigt vetenskapligt/konstnärligt)abstract
- Detta är den nionde utgåvan av den samlade översikten över fisk- och kräftdjursbeståndens status i våra vatten. Kunskap om fiskbestånden och miljön är en förutsättning för att utnyttjandet av fiskresurserna skall bli bärkraftigt. För svenska vattenområden beskrivs miljöutvecklingen i ett ekosystemsperspektiv, dels för att tydliggöra fiskens ekologiska roll och beskriva yttre miljöfaktorer som påverkar fiskbestånden, dels för att belysa fiskets effekter på miljön.Fiskbestånd och miljö i hav och sötvatten är utarbetad av Sveriges lantbruksuniversitet (SLU), Institutionen för akvatiska resurser (SLU Aqua), på uppdrag av Havs- och vattenmyndigheten. Rapporten sammanfattar utveckling och beståndsstatus för de kommersiellt viktigaste fisk- och kräftdjursarterna i våra vatten. Bedömningar och förvaltningsråd är baserade på Internationella Havsforskningsrådets (ICES) rådgivning, SLU Aquas nationella och regionala provfiskedata, samt yrkesfiskets rapportering.

Stress as a trigger of attacks in Menière's disease. A case-crossover study.
- 2004
-
Ingår i: The Laryngoscope. - : Wiley. - 0023-852X .- 1531-4995. ; 114:10, s. 1843-8
-
Tidskriftsartikel (refereegranskat)abstract
- BACKGROUND: Menière's disease is defined as the presence of recurrent, spontaneous episodic vertigo, hearing loss (HL), aural fullness, and tinnitus. The occurrence of attacks is unpredictable. The etiology is still unknown, but the disease has a pathologic correlate in hydropic distension of the endolymphatic system. Earlier studies have shown increased incidence of stress on the same day as vertigo attacks, but it has not been determined whether stress occurring on the day of the vertiginous episode came before or after the onset of the vertigo. METHODS: A case-crossover study including 46 patients with active Menière's disease. MAIN OUTCOME MEASURE: Relative risks with 95% confidence intervals (CI). FINDINGS: During the study period, 153 Menière's attacks were reported. Twenty-four (52%) of the 46 patients reported attacks. Twelve of the 153 (8%) attacks occurred within 3 hours after exposure to emotional stress. The relative risk of having an attack was 5.10 (95% CI 2.37-10.98) during 3 hours after being exposed to emotional stress. Twenty-nine percent of the patients with attacks had at least one attack after exposure to emotional stress. For mental stress, the relative risk was 4.16 (95% CI 1.46-11.83) and the hazard period 1 hour, but only five attacks were exposed. No excess risk was found after physical stress. INTERPRETATION: Being exposed to emotional stress increases the risk of getting an attack of Menière's disease during the next hour, and the hazard period is possibly extended up to 3 hours.

Report of the Baltic Fisheries Assessment Working Group (WGBFAS) : 14-21 April 2015, ICES HQ, Copenhagen, Denmark
- 2015
-
Rapport (övrigt vetenskapligt/konstnärligt)abstract
- The ICES Baltic Fisheries Assessment Working Group (WGBFAS) met 14-21 April 2015 (Chair: Mare Storr-Paulsen, Denmark), with 28 participants and 9 countries represented. The objective of WGBFAS was to assess the status of the following stocks:1 ) Sole in Division IIIa, SDs 20-222 ) Cod in Kattegat, Cod in SD 22-24, Cod in SD 25-323 ) Herring in SD 25-27, 28.2, 29 and 32, Herring in SD 28.1 (Gulf of Riga), Herring in SD 30, Herring SD 31.4 ) Sprat in SD 22-325 ) Plaice 21-23, Plaice 24256 ) Flounder 22-23; 24-25; 26+28 and 27+29-32, Brill 2232, Dab 2232, and Turbot 2232 (survey trends)WGBFAS also identified the data needed, for next year’s data call with some suggestions for improvements in the data call as well as in InterCatch. The report contains an introduction with the summary of other WGs relevant for the WGBFAS, country specific fishery description, the methods used, and ecosystem considerations. The results of the analytical stock assessment or survey trends for the species listed above are then presented with all the stocks with the same species in the same sections. The report ends with references, list of Working Documents, recommendations and Stock Annexes. In first quarter 2015 the Baltic cod stocks and the plaice stocks were benchmarked. As a result the Baltic cod stocks now have to apply a splitting key in SD 24 were both stocks are present. This has changed the assessment from being an area based assessment to now being a stock based assessments and has implications for the advice. The principle analytical models used for the stock assessments were XSA and SAM. For most flatfishes, CPUE trends from bottom trawl surveys were presented (except plaice 2425 and her31 using relative SSB from SAM and XSA, respectively). Ecosystem changes have been analytically considered in the following stock assessments: Herring in SD 25-27, 28.2, 29 and 32, and Sprat in SD 22-32, in form of cod predation mortality. Last year a very large retrospective pattern in the Eastern Baltic cod stock caused that the WG rejected the analytic assessment. Several uncertainties in the data lead to this conclusion i.a age reading problems with large inconsistency between and within nations as well as a change in growth and natural mortality. However, even though a data compilation workshop and a benchmark have been conducted in the intermediate time it was not possible to solve the main issue on growth. The lack of knowledge on growth caused to that even the length based data required in the data call was very uncertain for the models and in the end the WG was not able to produce a better model than was presented last year which is based on survey trends. The Her-30 (Herring in the Botnian Sea) was by the working group down scaled from a category 1 stock to a category 3 stock due to the commercial tuning fleet used in the assessment having very uncertain estimates in the last couples of years. However, during the Baltic ADG an alternative assessment was suggested were the stock is still considered a category 1 stock but the last 8 years of the commercial tuning fleet was terminated. This assessment was conducted after the working group but has been included in the report.

Benchmark workshop on Pandalus stocks (WKPRAWN)
- 2022
-
Rapport (övrigt vetenskapligt/konstnärligt)abstract
- Northern shrimp (Pandalus borealis) in divisions 3.a and 4.a East (Skagerrak and Kattegat and northern North Sea in the Norwegian Deep)An ensemble model was developed to incorporate uncertainty in natural mortality (SS3 model). A distribution of possible natural mortalities at age was constructed based on a suite of M life history and other type models. Three M scenarios were developed: a low, median and high M. An objective weighting approach was used based on model performance statistics and diagnostics to develop the final assessment. The reference points were estimated using a shortcut MSE approach testing a range of fishing mortalities and biomass thresholds in relation to virgin stock size (B0). Northern shrimp (Pandalus borealis) in subareas 1 and 2 (Northeast Arctic)For the Barents Sea stock, the accepted assessment model fell on SPiCT. The commercial CPUE used in the assessment was thoroughly investigated and standardized using a non-spatial model. A spatio-temporal modelling approach (sdmTMB) for the joint Norwegian/Russian Barents Sea Ecosystem Survey (BESS) was presented and compared to the design-based estimators currently used. There was some retrospective error on F/Fmsy but Based on the presented diagnostics, the reference model was considered adequate and acceptable. The standard approach for short-term forecasts and reference points was agreed.Flemish Cap shrimp (NAFO Div. 3M)There was limited progress on the Flemish Cap stock (pra.27.3M). An excellent long-term EU survey from 1988-present is available for the stock covering the period of the moratorium. This shows an increase from 2016 to 2019 with a subsequent decrease. Length-composition data are also available from the survey for this assessment. In future, it may be possible to explore an SS3 model for this stock given the partial and patchy nature of the available data.

Tidskriftsartikel (refereegranskat)abstract
- Purpose: To explore the feasibility and possible outcomes of a nursing intervention in patients with peripheral vestibular disorders. Design: A randomized controlled trial (RCT). Methods: Thirty-six patients participated in the study: the intervention group (n = 18), who received the intervention, and patients in a control group (n = 18), who received standard care. The intervention includes patient education and individualized nursing support during a 6-month rehabilitation period. Outcomes were symptoms, well-being, sense of coherence, and self-care measured at baseline before randomization and at 6 and 9 months later. Findings: At the 9-month follow up, the patients who received the intervention rated significantly fewer vertigo-related symptoms and a higher sense of coherence than the control group. Conclusion: The intervention was feasible and seems to support the patients to manage symptoms, but confirmative studies are warranted. Clinical Relevance: Patient education in combination with individual support may be beneficial to help patients with peripheral disorders during their rehabilitation.

Dizziness : a common, troublesome symptom but often treatable
- 2010
-
Ingår i: Journal of Vestibular Research-Equilibrium & Orientation. - : IOS Press. - 0957-4271 .- 1878-6464. ; 20:5, s. 391-398
-
Tidskriftsartikel (refereegranskat)abstract
- Objective: To investigate the prevalence of self-rated dizziness/unsteadiness and health as well as to estimate the proportion of participants with peripheral vestibular disorders. Methods: Altogether, 2547 participants (66%) participated in an epidemiological cross-sectional study, including self-rated questions about dizziness/unsteadiness, concomitant auditory symptoms and self-rated general, psychosocial and mental health. Results: The overall prevalence of dizziness was 21% and higher among women (27%) than men (14%) (p < 0.001). Dizziness, provoked by the movement of lying-down (benign paroxysmal positional vertigo), was noted in 5% of the participants with the symptom occurring more often in women than in men (p < 0.001). Twenty-four percent of the men and 21% of the women with dizziness simultaneously experienced a sense of rotation and loss of hearing and tinnitus. Fifteen percent reported falls because of dizziness. Both men and women suffering from dizziness symptoms perceived worse self-rated health generally, psychosocially and mentally than those without symptoms of dizziness (p < 0.001). Conclusion: Dizziness-related symptoms are common in all age groups and may manifest worse self-rated health. About 50% of the participants had symptoms indicating origin of peripheral vestibular disorders. Self-rated questions seem capable of identifying patients for referral to clinical examinations and subsequently those who can be successfully treated.

For most flatfishes and cod in SDs 25–32 (data limited stocks), CPUE trends from bottomtrawl surveys were used in the assessment (except plaice in SDs 24–25 for which relative SSB from SAM was used). For the data limited stocks, reference points based on length-based indicators were estimated (except cod in SDs 25-32 for which relative reference points were estimated using the SPiCT model). For cod in SDs 25–32, intersessional work was planned to hopefully allow returning to an analytical stock assessment in the near future. Ecosystem changes have been analytically considered in the following stock assessments: Herring in SD 25–27, 28.2, 29 and 32, and Sprat in SD 22–32, in form of cod predation mortality.

Function of semicircular canals, utricles and saccules in deaf children
- 2004
-
Ingår i: Acta Oto-Laryngologica. - : Informa UK Limited. - 0001-6489 .- 1651-2251. ; 124:1, s. 41-48
-
Tidskriftsartikel (refereegranskat)abstract
- OBJECTIVE: To study vestibular function in deaf children. MATERIAL AND METHODS: In 36 deaf children the function of the semicircular canals, saccules and utricles was measured by means of caloric testing, recordings of vestibular-evoked myogenic potentials (VEMPs) and measurements of the subjective visual horizontal (SVH) at different body tilts, respectively. RESULTS: In total, 30% of subjects had caloric hypo- or areflexia and 24% had a caloric asymmetry. VEMPs were weak or absent bilaterally in 22% of cases, and asymmetric in 19%. Regarding the utricle, 17% of subjects had a pathologically reduced perception of roll tilt to both sides and 25% had an asymmetry. In total, 30% of subjects were pathologic in all 3 tests and 30% were completely normal. Semicircular canal function correlated best with the function of the saccule. If hearing was better than 90 dB (pure-tone average of 0.5, 1.0 and 2.0 kHz) vestibular function was often normal. For hearing levels of 100-120 dB, otolith function declined significantly. CONCLUSIONS: Vestibular function tends to be preserved up to a point where hearing is nearly extinct. Hearing level correlates more closely with otolith function, especially that of the utricle, than with semicircular canal function.

Cod or clupeids? : economic consequences for fisheries operating in different ecosystem states
- 2013
-
Rapport (övrigt vetenskapligt/konstnärligt)abstract
- In the late 1980s, the cod population in the Baltic Sea declined steeply as a result of overfishing and unfavorable hydrological conditions for reproduction. Since then, restoring the Baltic cod stocks has been a major management objective in Swedish and EU fisheries policies. In addition to ecosystem benefits, restoring fish stocks is expected to have major economic consequences for the fisheries sector. The literature shows that profits from the fishery could increase by recovering the cod stock and reducing fishing pressure on herring and sprat since these are the main prey for the high valued cod. We explored the economic consequences for the Swedish fishery of fishing cod and clupeids (sprat and herring) at different total allowable catches (TAC) in the Baltic Sea. We compared profits to the fishery by studying combinations of high and low TACs of cod and sprat, respectively, based on biological scenarios. The analysis contributes to the literature by explicitly modeling how changes in the ecosystem could affect the optimal fleet structure and economic performance of different fleet segments. The Swedish fishery was used as a case study within the Baltic Sea, acknowledging that the Baltic Sea is utilized for fishing by all states in the region and that other countries might face other consequences. Further, the fishing sector is a complex industry characterized by vessels participating in multiple fisheries. Each vessel will exploit several fish stocks enabling the fisherman to choose among stocks. If the fishing possibilities change, the fisherman will look for alternative fishing activities for using the company's labor and capital assets. Thus - through rational economic decisions made by the fishing industry - a management action in one fishery will lead to effects in other fisheries that might be difficult for managers to predict. The analyses were performed using the Swedish Resource Rent Model for the Commercial Fishery, SRRMCF, which is an economic model covering the entire Swedish fishery. The main conclusions from the study were that it was more profitable to fish the three species at FMSY than at the current utilization levels and that the economic profitability could be further increased by up to 118 MSEK by increasing the cod stock at the expense of reducing sprat abundance. These effects rely on all stocks being fished at sustainable levels.
