Can waste re-cycling increase the sustainability of animal feeds?
Jobling, Malcolm (Journal article; Tidsskriftartikkel, 2019)An annual procution of over one billion tonnes, and an economic turnover in excess of $US400 billion; this is the animal feed industry. The vast majority of animal feed is given to terrestrial farm animals; those reared for meat, and those used to produce eggs and dairy products. Fish feeds make up about 5% of the total volume of animal feeds and have a 10% share of marked sales. <p> <p>It is ... -

Dietary effects on biomarkers of growth, stress, and welfare of diploid and triploid Atlantic salmon (Salmo salar) during parr-smolt transformation
Bortoletti, Martina; Maccatrozzo, Lisa; Peruzzi, Stefano; Strand, Jo Espen Tau; Jobling, Malcolm; Radaelli, Giuseppe; Bertotto, Daniela (Journal article; Tidsskriftartikkel; Peer reviewed, 2022-04-12)Triploidy is induced in Atlantic salmon (Salmo salar) to produce sterile fish for genetic containment and to hinder early sexual maturation in farmed fish, but it can have unwanted negative effects on growth, health, and welfare. However, the growth and welfare of triploid fish may be improved by adjusting the rearing environment, feeding conditions and diets. This study evaluated physiological ... -
Digestive tract morphology and enzyme activities of juvenile diploid and triploid Atlantic salmon (Salmo salar) fed fishmealbased diets with or without fish protein hydrolysates
Martinez-Llorens, Silvia; Peruzzi, Stefano; Falk-Petersen, Inger Britt; Godoy-Olmos, Sergio; Ulleberg, Lars-Olav; Tomas-Vidal, Ana; Puvanendran, Velmurugu; Kwame Odei, Derrick; Hagen, Ørjan; Fernandes, Jorge Manuel de Oliveira; Jobling, Malcolm (Journal article; Tidsskriftartikkel; Peer reviewed, 2021-01-11)Triploid, sterile Atlantic salmon (Salmo salar) could make a contribution to the development of the farming industry, but uncertainties about the performance and welfare of triploids have limited their adoption by farmers. In this study, we compared the ontogeny of digestive tract morphology and enzyme activities (pepsin, trypsin, chymotrypsin, alkaline phosphatase and aminopeptidase) of diploid ... -
Environmental perturbation and fish populations: Are fish in hot water?
Jobling, Malcolm (Journal article; Tidsskriftartikkel, 2008)The theme of this issue of Fiskerikandidaten is ‘The environment’; this has become a hot topic. The word environment crops up in many different contexts; in scientific literature, in the titles of meetings and conferences, in legislative and regulatory documents, in the media and popular press and on a multitude of internet sites. Discussions about the environment often revolve around ... -

Growth and development of skeletal anomalies in diploid and triploid Atlantic salmon (Salmo salar) fed phosphorus-rich diets with fish meal and hydrolyzed fish protein
Peruzzi, Stefano; Puvanendran, Velmurugu; Riesen, Guido; Ripman Seim, Rudi; Hagen, Ørjan; Martínez-Llorens, Silvia; Falk-Petersen, Inger-Britt; Fernandes, Jorge Manuel de Oliveira; Jobling, Malcolm (Journal article; Tidsskriftartikkel; Peer reviewed, 2018-03-22)Diploid and triploid Atlantic salmon, <i>Salmo salar</i> were fed high-protein, phosphorus-rich diets (56–60% protein; ca 18g phosphorus kg<sup>-1</sup> diet) whilst being reared at low temperature from start-feeding until parr-smolt transformation. Performances of salmon fed diets based on fish meal (STD) or a mix of fishmeal and hydrolysed fish proteins (HFM) as the major protein sources were ... -
Growth and Gut Morphology of Diploid and Triploid Juvenile Atlantic Cod (Gadus morhua)
Vargas, Cecilia; Hagen, Ørjan; Solberg, Christel; Jobling, Malcolm; Peruzzi, Stefano (Journal article; Tidsskriftartikkel; Peer reviewed, 2014)The objective of this paper was to compare the growth and gut morphology of juvenile diploid and triploid Atlantic cod (Gadus morhua) reared under similar conditions. Individually tagged 36-week old diploid (mean weight 49.3 ± 13.8 g) and triploid (mean weight 43.6 ± 11.2) juvenile cod were measured at intervals during a 29-weeks growth trial. Data for weight, length, condition factor (K), hepato-somatic ... -
Gut morphology of diploid and triploid Atlantic salmon (Salmo salar L.)
Peruzzi, Stefano; Hagen, Ørjan; Jobling, Malcolm (Journal article; Tidsskriftartikkel; Peer reviewed, 2014)Triploid fish may differ from diploids in a number of morphological and physiological characteristics. The present study was undertaken to examine the effects of ploidy on the gut morphology of Atlantic salmon post-smolts (Salmo salar L.). For this purpose, we compared the intestinal length (relative gut length, RGL), pyloric caeca number and mass of commercially produced diploid and triploid siblings. ... -

Seasonal Differences in Relative Gene Expression of Putative Central Appetite Regulators in Arctic Charr (Salvelinus alpinus) Do Not Reflect Its Annual Feeding Cycle
Striberny, Anja; Ravuri, Chandra Sekhar; Jobling, Malcolm; Jørgensen, Even Hjalmar (Journal article; Tidsskriftartikkel; Peer reviewed, 2015-09-30)The highly seasonal anadromous Arctic charr (Salvelinus alpinus) was used to investigate the possible involvement of altered gene expression of brain neuropeptides in seasonal appetite regulation. Pro-opiomelanocortin (POMCA1, POMCA2), Cocaine and amphetamine regulated transcript (CART), Agouti related Peptide (AgRP), Neuropeptide Y (NPY) and Melanocortin Receptor 4 (MC4-R) genes were examined. The ... -
