Protein and energy nutrition of marine gadoids, Atlantic cod (Gadus morhua L.) and haddock (Melanogrammus aeglefinus L.)
No full text Primary goals of this thesis were to: 1) examine the in vivo digestion of macronutrients from conventional or alternative feed ingredients used in practical diets of juvenile gadoids (Atlantic cod and haddock), 2) document growth potential of fish at the juvenile grower phase given varying levels of dietary protein and energy and 3) assess the potential of in vitro pH-Stat methods for rapid screening protein quality of feed ingredients, specifically for gadoids. All primary research questions were linked to and built upon one another with the goal of gaining a better understanding of protein and energy utilization of juvenile grower phase gadoids. Studies showed that cod and haddock have a high capacity to utilize a wide range of dietary feed ingredients, such as fish meals, zooplankton meal, soybean products (meal, concentrate and isolate) and wheat gluten meal. New dietary formulations for gadoids may also utilize pulse meals, corn gluten meal, canola protein concentrate and crab meal. Digestibility data in this thesis is currently the only research that examined both in vivo and in vitro macronutrient digestibility of a large number and wide range of individual ingredients, specifically for gadoids. This is essential to gain new knowledge on protein and energy utilization as well as for least-cost ration formulations and effective substitution of ingredients into new formulations. Data has demonstrated a dietary digestible protein/digestible energy (DP/DE)ratio of 30 g DP/MJ DE is required for gadoids during the juvenile phase (in vitro closed-system pH-Stat assay for rapid screening protein quality of test ingredients that is ‘species-specific’ to gadoids. It is demonstrated that in vitro results generally reflected results obtained through conventional in vivo protein digestibility methods. Studies resulted in the first generation of a ‘gadoid-specific’ proteolytic enzyme extraction method and in vitro closed-system pH-Stat assay which may be useful to investigate protein digestion, absorption and metabolism of gadoids and further development of their feeds. </p

Effect of dietary lipid level on fatty acid beta-oxidation and lipid composition in various tissues of haddock, Melanogrammus aeglefinus L
No full textHaddock (Melanogrammus aeglefinus) is a gadoid fish species that deposits dietary lipid mainly in the liver. The fatty acid (FA) beta-oxidation activity of various tissues was evaluated in juvenile haddock fed graded levels of lipid. The catabolism of a radiolabelled FA, [1-(14)C]palmitoyl-CoA, through peroxisomal and mitochondrial beta-oxidation was determined in the liver, red and white muscle of juvenile haddock fed 12, 18 and 24% lipid in the diet. There was no significant increase in the mitochondrial or peroxisomal beta-oxidation activity in the tissues tested as the dietary lipid level increased from 12 to 24%. Peroxisomes accounted for 100% of the beta-oxidation observed in the liver, whereas mitochondrial beta-oxidation dominated in the red (91%) and white muscle (97%) of juvenile haddock. Of the tissues tested, red muscle possessed the highest specific activity for beta-oxidation expressed on a per mg protein or per g wet weight basis. However, white muscle, which forms over 50% of the body mass in gadoid fish was the most important tissue in juvenile haddock for overall FA catabolism. The total lipid and FA composition of these tissues were also determined. This study confirmed that the liver was the major lipid storage organ in haddock. The hepatosomatic index (HSI; 10.0-15.2%) and lipid (73.8-79.3% wet wt.) in the liver increased significantly as dietary lipid was increased from 12 to 24% lipid. There was no significant increase in the lipid composition of the white muscle (0.8% wet wt.), red muscle (1.9% wet wt.) or heart (2.5% wet wt.).LR: 20061115; PUBM: Print; JID: 9516061; 0 (Carbon Radioisotopes); 0 (Dietary Fats); 0 (Fatty Acids); 0 (Lipids); 0 (Lipoproteins, VLDL); 1763-10-6 (Palmitoyl Coenzyme A); ppublishSource type: Electronic(1
Going Beyond Counting First Authors in Author Co-citation Analysis
No full textThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed

Lipid metabolism of haddock (Melanogrammus aeglefinus)
No full textHaddock, a commercially important coldwater marine fish accumulates a high amount of dietary lipid in the liver (>60% lipid, wet weight). Several experiments were conducted to study the dietary lipid utilization by haddock, their lipid transport mechanisms and the biochemical basis of liver lipid deposition and catabolism. Juvenile haddock (6.9g) were fed three isonitrogenous diets containing 14, 16, 19 and 22% lipid to examine the effects of dietary lipid on growth, feed utilization, hepatosomatic index (HSI) and tissue lipid accumulation. Growth and feed efficiency of haddock was not significantly affected by increasing the lipid content of the diet. A significant increase in HSI (9.8–12.1%) and total liver lipid content (63.2–69.0%) was observed in haddock fed 14% versus 22% lipid, however, total muscle lipid content was unaffected. The liver fatty acid (FA) composition mirrored that of the diet. The muscle lipid (1%) contained a high proportion of polar lipid (84% lipid) and polyunsaturated FA (53% total FA). A dietary lipid level of 14% or less is recommended for use in juvenile haddock grower diets based on the results of this study. A series of liver function tests were also performed on the plasma of cultured haddock grouped on the basis of their HSI. No significant differences were observed between the 11.1, 13.0 and 17.3% HSI groups for any of the liver function parameters tested.Serum lipoproteins of post-absorptive juvenile haddock showed that HDL (high density lipoprotein) was the predominant lipoprotein class (1517 mg/dL) followed by LDL (low density lipoprotein; 467 mg/dL). A low level of VLDL (very low density lipoprotein; <50 mg/dL) was observed in serum. The concentration of total lipid in the serum averaged 1297 mg/dL. The phospholipid (PL), triacylglycerol (TG), cholesterol ester (CE) and cholesterol (CL) contents of serum were 57, 16, 16 and 11%, respectively. The fatty acid (FA) composition of HDL resembled that of the serum lipid and PL and it contained a higher percentage (51%) of polyunsaturated FA than VLDL (36%). High molecular weight apo B-like proteins were observed in the VLDL and LDL fractions. An apo A-I-like protein was predominant in the HDL fraction. The low level of VLDL (<50mg/dL) circulating in the serum suggests a low level of lipid (triacylglycerol) transport from the liver to the muscle in haddock.

Dispelling the Myths Behind First-author Citation Counts
No full textWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
Haddock (Melanogrammus aeglefinus) in Division 5.b (Faroes grounds)
No full textICES advises on the basis of the MSY approach that there should be no directed fishery on haddock in 2014. Measures should be put in place to minimize bycatches of haddock in other fisheries. A recovery plan should be developed and implemented as a prerequisite to reopening the directed fishery. All catches are assumed to be landed.</p
