Utilization of feed resources in the production of rainbow trout (Oncorhynchus mykiss) in Norway in 2020

The utilization of feed resources in Norwegian farming of Atlantic salmon has been reported for 2010, 2012, 2016 and 2020. The present paper is a corresponding documentation for farming of rainbow trout in Norway in 2020. 89,667 tonnes of rainbow trout were produced, which is 6 % of the amount of salmon produced. The 116,990 tonnes of ingredients used for feed sold as trout feed were produced from 13.4 % marine protein sources, 10.8 marine oils, 39.7 % vegetable protein sources, 19.9 % vegetable oils, 12.1 % carbohydrate sources and 3.9 % micro ingredients, which include vitamin and mineral premixes, crystalline amino acids and astaxanthin. In addition, was 0.2 %, or 257 tonnes, of single cell protein, insect meal, fermented products and microalgae used in trout feed. Norwegian fish meal and fish oil constituted 8.8 % of the ingredients, and the remaining 91.2 % were imported ingredients. The economic feed conversion factor (FCR) was 1.30, 1.21 or 1.44 if calculated from feed ingredients ‘as is’, feed ingredients on dry matter basis, or from registered traded feed, respectively. The trout retained 37 %, 43 %, 33 %, 63 % and 63 % of the feed’s dry matter, energy, protein, fat and EPA+DHA, respectively, in the whole body. In fillet, the corresponding retention values were 21 %, 25 %, 23 %, 34 % and 35 %, respectively. The feed utilization in trout was slightly overestimated because of some salmon feed used in the trout production. The feed ingredients used and the feed utilization in trout farming in 2020 were similar to the data for salmon farming, but trout is produced in a smaller quantity.Utilization of feed resources in the production of rainbow trout (Oncorhynchus mykiss) in Norway in 2020publishedVersio

Utilization of feed resources in the production of Atlantic salmon (Salmo salar) in Norway: An update for 2020

The utilization of feed resources in Norwegian salmon farming has previously been reported for 2010, 2012 and 2016. This paper presents an update for 2020, giving an overview of the feed ingredients used and retention of nutrients in fillet and whole salmon for the entire Norwegian salmon production. A total of 1,976,709 tonnes of feed ingredients were used to produce 1,467,655 tonnes of salmon. The feed was produced from 22.4 % marine ingredients, 73.1 % vegetable ingredients and 4.1 % micro ingredients such as vitamin and mineral premixes, astaxanthin and crystalline amino acids. In addition, 0.4 %, or 8126 tonnes, of single cell protein, insect meal, fermented products and microalgae were used in salmon feeds. Norwegian marine protein and marine oil constituted 8.3 % of the ingredients. The remaining 91.7 % of the ingredients were imported. The feed conversion factor was 1.35 if calculated from feed ingredients ‘as is’, or 1.25 if calculated form ingredients on dry matter basis. The retention of energy, dry matter, protein, fat, EPA + DHA and phosphorus from feed was 39 %, 33 %, 34 %, 57 %, 49 % and 25 %, respectively, in whole salmon. In fillet, the corresponding retention rates were 25 %, 21 %, 25 %, 35 %, 32 % and 12 %, respectively. The feed ingredients used and the utilization of feed in 2020 resembled that of 2016, except that there was an increase in the amount produced in 2020 and a slight increase in the economic feed conversion ratio (eFCR).Utilization of feed resources in the production of Atlantic salmon (Salmo salar) in Norway: An update for 2020publishedVersio

Chemical composition of whole body and fillet of slaughter sized Atlantic salmon (Salmo salar) and rainbow trout (Oncorhynchus mykiss) farmed in Norway in 2020

The fish is the end-product in fish farming, but updated data on the composition of slaughter sized farmed salmon and trout are still scarce. The body composition of farmed salmonids changes over time as farming technology, farming routines, feed and genetics develops. Knowledge of the body composition of the farmed fish thus depends on data on today’s produced fish. The body composition also varies with time of the year, geography, feed composition and feed intake. Analysis of samples representative of the whole Norwegian production of salmon and trout requires fish collected from the different geographic areas of production, sampled at different times throughout the year, and fish fed feeds from different feed producers. Atlantic salmon and rainbow trout was collected in summer and in winter. Salmon was collected at four different locations, and trout at two different locations at each sampling time. Whole body and fillet of salmon and trout was analyzed. This study reports the average content of energy, dry matter, ash, crude protein, crude lipids, iron, potassium, calcium, copper, magnesium, sodium, zinc and phosphorus in whole body and fillet of Atlantic salmon and rainbow trout produced in Norway in 2020. Moreover, are the amino acid profiles and the fatty acid profiles given.Chemical composition of whole body and fillet of slaughter sized Atlantic salmon (Salmo salar) and rainbow trout (Oncorhynchus mykiss) farmed in Norway in 2020publishedVersio

Impact of EMG Changes in Continuous Vagal Nerve Monitoring in High-Risk Endocrine Neck Surgery

Background: Continuous vagal intraoperative neuromonitoring (CIONM) of the recurrent laryngeal nerve (RLN) may reduce the risk of RLN lesions during high-risk endocrine neck surgery such as operation for large goiter potentially requiring transsternal surgery, advanced thyroid cancer, and recurrence. Methods: Fifty-five consecutive patients (41 female, median age 61 years, 87 nerves at risk) underwent high-risk endocrine neck surgery. CIONM was performed using the commercially available NIM-Response 3.0 nerve monitoring system with automatic periodic stimulation (APS) and matching endotracheal tube electrodes (Medtronic Inc.). All CIONM events (decreased amplitude/increased latency) were recorded. Results: APS malfunction occurred on three sides (3 %). A total of 138 CIONM events were registered on 61 sides. Of 138, 47 (34 %) events were assessed as imminent (13 events) or potentially imminent (34 events) lesions, whereas 91 (66 %) were classified as artifacts. Loss of signal was observed in seven patients. Actions to restore the CIONM baseline were undertaken in 58/138 (42 %) events with a median 60 s required per action. Four RLN palsies (3 transient, 1 permanent) occurred: one in case of CIONM malfunction, two sudden without any significant previous CIONM event, and one without any CIONM event. The APS vagus electrode led to temporary damage to the vagus nerve in two patients. Conclusions: CIONM may prevent RLN palsies by timely recognition of imminent nerve lesions. In high-risk endocrine neck surgery, CIONM may, however, be limited in its utility by system malfunction, direct harm to the vagus nerve, and particularly, inability to indicate RLN lesions ahead in time.publishedVersio

KEMAMPUAN PENALARAN STATISTIS, KOMUNIKASI STATISTIS, DAN ACADEMIC HELP-SEEKING MAHASISWA MELALUI PEMBELAJARAN BERBASIS PROYEK BERBANTUAN ICT

Penalaran dan komunikasi statistis, serta academic help-seeking (AHS) merupakan aspek penting bagi perkembangan pengetahuan mahasiswa. Komunikasi statistis penting untuk memperjelas suatu masalah berdasarkan karakteristik data statistik dan penalaran statistis berperan membentuk keterampilan mahasiswa menggunakan konsep, aturan dan proses statistika, sementara AHS merupakan strategi self-regulatory penting yang memberikan kontribusi untuk belajar statistika. Kompetensi mahasiswa terhadap ketiga aspek tersebut masih rendah sehingga perlu dikembangkan dalam pembelajaran pengantar statistika. Salah satu model pembelajaran alternatif yang dapat mencapai kompetensi dimaksud adalah pembelajaran berbasis proyek berbantuan ICT (PBP berbantuan ICT). Penelitian ini bertujuan untuk menganalisis secara komprehensif pencapaian dan peningkatan kemampuan penalaran statistis (KPS) dan kemampuan komunikasi statistis (KKS), serta pencapaian AHS mahasiswa melalui PBP berbantuan ICT. Penelitian ini menggunakan metode campuran dengan desain kelompok kontrol pretes-postes. Populasi dalam penelitian ini adalah mahasiswa S1 program studi Pendidikan Matematika pada salah satu universitas di Maluku Utara. Instrumen pengumpulan data meliputi: tes kemampuan awal statistis (KAS), pretes dan postes KPS dan KKS, skala AHS, lembar observasi dan wawancara. Analisis data menggunakan statistik uji: t, t^', Mann-Whitney U, anova dua jalur, dan uji asosiasi. Hasil penelitian menunjukkan bahwa: (1) pencapaian KPS, KKS, dan AHS mahasiswa yang memperoleh PBP berbantuan ICT secara signifikan lebih tinggi daripada mahasiswa yang memperoleh pembelajaran konvensional (PK), (2) Peningkatan KPS dan KKS mahasiswa yang memperoleh PBP berbantuan ICT secara signifikan lebih tinggi daripada PK ditinjau dari KAS (tinggi dan sedang), (3) Peningkatan KPS dan KKS mahasiswa yang memperoleh PBP berbantuan ICT dengan KAS tinggi dalam kategori tinggi, KAS (sedang, rendah) dalam kategori sedang, dan mahasiswa yang memperoleh PK dengan KAS (tinggi, sedang, rendah) dalam kategori sedang, (4) Tidak terdapat pengaruh interaksi antara faktor pembelajaran dan KAS terhadap pencapaian dan peningkatan KPS dan KKS mahasiswa, (5) Tidak terdapat pengaruh interaksi antara pembelajaran dan KAS terhadap pencapaian AHS mahasiswa, (6) Ada asosiasi yang signifikan dan bersifat positif antara KPS dan KKS mahasiswa, KKS dan AHS mahasiswa yang diterapkan melalui PBP berbantuan ICT, namun tidak ada asosiasi yang signifikan antara KPS dan AHS, dan (7) Asosiasi antara KPS dan KKS dalam kategori kuat, antara KPS dan AHS dalam kategori kurang kuat, dan antara KKS dan AHS dalam kategori cukup kuat. PBP berbantuan ICT dapat digunakan sebagai salah satu modal alternatif dalam pembelajaran pengantar statistika untuk meningkatkan KPS dan KKS, serta menciptakan academic help-seeking statistis mahasiswa. ---------- Statistical reasoning and communication and academic help-seeking (AHS) are important aspects for students’ knowledge development. Statistical communication is important to clarify a problem, based on the characteristics of statistic data and statistical reasoning plays role to form students skill in using concepts, rules and statistics process. While academic help-seeking is self-regulatory strategy that contributes to learn statistics. The students still did not have enough ability in three competencies. One of alternative models enhances students’ ability in those three competencies is project-based learning assisted ICT (ICT-assisted PBL). This study aims to analyze comprehensively the achievement and improvement of statistical reasoning ability (SRA) and statistical communication ability (SCA), as well as students’ AHS through ICT-assisted PBL. This study used a mixed methods with pretest posttest control design. The population of this ware undergraduate students of Mathematics Education program at a State University in North Maluku. Data collection instruments include: prior statistical knowledge (PSK) test, pre-test and post-test of statistical reasoning ability and communication statistical ability, AHS scale, observation note and interviews. Analysis statistic used test: t, t', Mann-Whitney U, two-ways ANOVA, and the association test. The results showed that: (1) the students who got with ICT-assisted PBL have higher achievement in SRA, SCA, and AHS than students who got convensition learning (CL), (2) high, middle and low PSK students who got ICT-assisted PBL have enhancement and achievement significantly higher than CL. (3) Improved students’ AHS behavior who got ICT-assisted PBL bases on student’s PSK high, medium and low are in the low category, (4) there is a direct effect of the learning factor and prior statistical knowledge (PSK) to the students’ achievement and improvement of SRA, SCA and AHS, but simultaneously there is no interaction between factors learning and PSK to the student’s achievement and improvement of SRA and SCA, (5) there is not interaction between learning factors and PSK on students’ academic help-seeking, (6) there is significant assosiation and positive between student’s SRA and SCA, student’s SCA and AHS who receive ICT-assisted PBL, but not is significant association between student’s SRA and AHS, and (7) The association between student’s SRA and SCA in the highle category, between the student’s SRA and the AHS in the lower category, and between student’s SCA and AHS in middle category. ICT-assisted PBL can be used as an alternative model in teaching and learning statistics to enhancement statistical reasoning ability and statistical communication and students’ statistical academic help-seeking

Effect of high-pressure pretreatment on enzymatic hydrolysis of a mixture of rainbow trout (Oncorhynchus mykiss) and Atlantic salmon (Salmo salar) rest raw material

IntroductionFish rest raw material generated from the fish processing industry may be a useful resource for recovery of added value compounds. The application of non-thermal novel technologies can improve the extraction. High-pressure processing (HPP) has long been used for the preservation and extension of the shelf life of seafood. It also constitutes a promising technology for the increased recovery of valuable compounds, such as lipids and proteins. The objective of this study was to assess the yield and the chemical composition of the fractions obtained after enzymatic hydrolysis on a mixture of Atlantic salmon (Salmo salar) and rainbow trout (Oncorhynchus mykiss) rest raw material pretreated by high-pressure (HP).MethodsSix different pretreatments were applied prior to enzymatic hydrolysis; 600 MPa x 8  min, 600 MPa x 4  min, 400 MPa x 8  min, 400 MPa x 4  min, 200 MPa x 8  min, 200 MPa x 4  min.Results and discusssionThese applied pretreatments did not yield higher oil extraction compared to the control. However, the fish protein hydrolysates (FPH) contained higher amount of protein when compared to the FPH obtained from the control

Vannforekomsters sårbarhet for avrenningsvann fra vei under anleggog driftsfasen

-Bygging og drift av vei kan påføre vannmiljøet en rekke ulike belastninger. Her har vi tatt for oss forurenset veivann fra anleggs- og driftsfasen som vil kunne forringe vannmiljøet. Ofte benyttes begrepet sårbar resipient (vannforekomst) når man vurderer en belastning som vannmiljøet utsettes for. Begrepet er sjeldent definert, og kriteriene som ligger til grunn for å vurdere sårbarheten mangler. I denne rapporten har vi definert sårbarhet som: «En vannforekomst sin evne til å tåle og eventuelt restitueres etter aktiviteter eller endringer i miljøforholdene». Med bakgrunn i vannforskriften, naturmangfoldloven og vannfaglig kompetanse har vi samlet kriterier som vi mener er viktige for å vurdere en vannforekomst sin sårbarhet for avrenningsvann fra vei. Kriteriene som bygger på vannforskriften og naturmangfoldloven har blitt sammenstilt i to Excel-baserte regneark, utformet som to matriser. Etter angitte føringer gis hvert kriterium poengscore 1, 2 eller 3, og avhengig av gjennomsnittlig poengscore, klassifiseres vannforekomsten videre i en av tre sårbarhetskategorier: «Lav», «Middels» eller «Høy». Informasjon for vurdering av sårbarhetskriteriene for den aktuelle vannforekomst hentes i hovedsak fra www.Vann- Nett.no, www.Vannportalen.no, www.Naturbase.no og www.artskart.artsdatabanken.no. Matrisene kan benyttes i ulike planleggingsfaser for vurdering av behov for avbøtende tiltak for vannmiljøet under anleggs- og driftsfasen av veiprosjekter. Sårbarhetskriteriene i matrisene er utviklet for bekker, elver og innsjøer, ikke kystvann og grunnvann. Verktøyet (matrisene og rapporten) er beregnet for personer som jobber med vannfaglige problemstillinger i veiplanlegging knyttet til anleggs- og driftsfase

DNA methylation profiling in doxorubicin treated primary locally advanced breast tumours identifies novel genes associated with survival and treatment response

<p>Abstract</p> <p>Background</p> <p>Breast cancer is the most frequent cancer in women and consists of a heterogeneous collection of diseases with distinct histopathological, genetic and epigenetic characteristics. In this study, we aimed to identify DNA methylation based biomarkers to distinguish patients with locally advanced breast cancer who may benefit from neoadjuvant doxorubicin treatment.</p> <p>Results</p> <p>We investigated quantitatively the methylation patterns in the promoter regions of 14 genes (<it>ABCB1</it>, <it>ATM</it>, <it>BRCA1</it>, <it>CDH3</it>, <it>CDKN2A</it>, <it>CXCR4</it>, <it>ESR1</it>, <it>FBXW7</it>, <it>FOXC</it>1, <it>GSTP1</it>, <it>IGF2</it>, <it>HMLH1</it>, <it>PPP2R2B</it>, and <it>PTEN</it>) in 75 well-described pre-treatment samples from locally advanced breast cancer and correlated the results to the available clinical and molecular parameters. Six normal breast tissues were used as controls and 163 unselected breast cancer cases were used to validate associations with histopathological and clinical parameters.</p> <p>Aberrant methylation was detected in 9 out of the 14 genes including the discovery of methylation at the <it>FOXC1 </it>promoter. Absence of methylation at the <it>ABCB1 </it>promoter correlated with progressive disease during doxorubicin treatment. Most importantly, the DNA methylation status at the promoters of <it>GSTP1</it>, <it>FOXC1 </it>and <it>ABCB1 </it>correlated with survival, whereby the combination of methylated genes improved the subdivision with respect to the survival of the patients. In multivariate analysis <it>GSTP1 </it>and <it>FOXC1 </it>methylation status proved to be independent prognostic markers associated with survival.</p> <p>Conclusions</p> <p>Quantitative DNA methylation profiling is a powerful tool to identify molecular changes associated with specific phenotypes. Methylation at the <it>ABCB1 </it>or <it>GSTP1 </it>promoter improved overall survival probably due to prolonged availability and activity of the drug in the cell while <it>FOXC1 </it>methylation might be a protective factor against tumour invasiveness. <it>FOXC1 </it>proved to be general prognostic factor, while <it>ABCB1 </it>and <it>GSTP1 </it>might be predictive factors for the response to and efficacy of doxorubicin treatment. Pharmacoepigenetic effects such as the reported associations in this study provide molecular explanations for differential responses to chemotherapy and it might prove valuable to take the methylation status of selected genes into account for patient management and treatment decisions.</p
