Monitoring mosselzaadinvang met MZI Wieringen in Waddenzee 2008

In de Waddenzee is in 2008 een experiment uitgevoerd ten behoeve van verbreding van kennis over mosselzaadinvang (MZI) op de percelen Wieringen 36 en 37. Hierbij is gebruik gemaakt van twee op de bodem geplaatste kooiconstructies met daarin collectortouwen die het zaad in kunnen vangen. Doel van het project is het onderzoeken van de mogelijkheden voor mosselinvang met behulp van speciaal ontwikkelde kooiconstructies met ‘fuzzy rope’ touw als collectoren. Hierbij is door Wageningen IMARES de invangcapaciteit, invangefficiëntie en groei-efficiëntie op de collectortouwen bepaald en zijn het aantal mossellarven in het water gemonitord. Een ander doel voor de ondernemer was ervaring opdoen met het plaatsten en oogsten van de installatie. Verder zijn observaties van en door de kweker gerapporteerd; dit betreft (1) de oogst, (2) de aanwezigheid van vogels en zeezoogdieren en (3) de visuele kenmerken van de invangsystemen, waarbij de landschappelijke effecten met behulp van foto’s in beeld zijn gebracht. Voor effecten op bodem en bodemfauna wordt gerefereerd aan het PRODUS project. De gekozen locatie is geschikt voor mosselzaadinvang; dit blijkt uit de aanwezigheid van schelpdierlarven in het water en schelpdierbroed en -zaad op de touwen. Ook de constructie is technisch/biologisch geschikt voor zaadinvan

MZI Monitoring en oogst van vier experimenten in Waddenzee en Oosterschelde 2008

Doel van het onderzoek was om met een viertal ondernemers een gezamelijke mzi monitoring uit te voeren op de oogst van vier verschillende MZI projecten: EMERGO, MIOS, de Rooij Mosselkweek en Mosselkweek Barbé B.V. De monitoring heeft plaatsgevonden op een uniforme wijze, aan boord van het oogstschip. De resultaten van de monitoring zijn collectief gerapporteerd. De eigen waarneming en monitoringgegevens van iedere ondernemer over ecologische effecten, landschappelijke effecten en totale oogst zijn apart onderdeel van de rapportage

PRODUS 1 d: Rendement MZI zaad op percelen 2005-2008

Fluctuaties in aanbod van mosselzaad en druk op de visserij hebben er toe geleid dat de sector mosselzaadinvangsystemen (MZI's) is gaan ontwikkelen. Door de extra kosten aan arbeid en materiaal is MZI zaad duurder dan traditioneel gevist zaad, daarom is een hoog rendement van het mosselzaad tijdens doorkweek op de percelen van belang. Dit is het onderwerp van studie van PRODUS deelproject 1d. Het rendement wordt bepaald door groei en overleving van het zaad. Het onderzoek heeft zich gericht op factoren die de groei en overleving van MZI zaad kunnen beïnvloeden. Het huidige rapport geeft een samenvatting van het onderzoek dat is uitgevoerd in de periode 2005-2008

Feasibility and acceptability of aquatic exercise therapy in burn patients – A pilot study

Background: As the assistive and resistive properties of water can facilitate the performance of exercise, aquatic exercise therapy might be a promising rehabilitation modality for burn patients. This study aimed to investigate the feasibility and acceptability of aquatic exercise therapy in adult burn patients with an indication for supervised exercise therapy. Methods: Eligible for this observational pilot study were all competent adult burn patients with an indication for supervised exercise therapy who had been admitted to the burn centre of the Maasstad Hospital between June 2016 and February 2017. Patients were asked to participate in an in-hospital aquatic exercise therapy program for a minimum of 2 weeks, 2 times per week, or otherwise serve as control by having land-based exercise therapy (regular care). Feasibility of aquatic exercise therapy was assessed by comparing the number of eligible patients to the number of patients that could actually participate, monitoring attendance rates, monitoring complications, and evaluating early experiences. Acceptability was assessed using the Water Exercise Acceptability Questionnaire. Results: Eleven patients were invited and ten of them agreed to participate. All chose aquatic instead of land-based exercise therapy. Participants were aged between 19 and 64 years and their burns affected 18–53% of total body surface area (TBSA). Aquatic exercise therapy appeared feasible in nine of 13 eligible patients (69%). Attendance rates were high (42–100%) and the majority of participants (n = 9) continued with aquatic exercise therapy beyond the initial two weeks. No serious complications (e.g. infections) occurred. Adverse symptoms (wound healing issues) were reported in five participants, but in four of them these were not likely to be due to the aquatic exercise therapy. Enjoyment was high and adherence to the aquatic exercise therapy was further facilitated by support from staff, a sense of achievement, noticeable improvements, personal motivation, and support from other participants. Peer support was reported as a positive side effect. Conclusions: These preliminary results indicate that aquatic exercise therapy is both feasible and acceptable for the majority of adult burn patients with an indication for supervised exercise therapy. No indications were found for an increased risk of infection or other serious complications.</p
