    Hard days and nights: hardships at work, a lack of support at home, and little or no social security combine to create a bleak future for women fishsellers in Mangalore, India

    Mangalore is a port city situated in the west coast state of Karnataka in India. The city hosts both large-scale and small-scale fisheries along its coastline. Traditionally, fishermen catch the product and sell it at a daily auction in the harbour to women vendors, who thereafter transport the goods to the market for commercial sale. The trade starts early in the morning, when the fishermen return to the harbour from their nightly fishing

    Skillnader i odling av kall- respektive varmvattenfisk i RAS

    Get PDF
    Anledningen till att studien gjordes Àr det ökande behovet av protein för humankonsumtion, i kombination med ett ökat antal tomma djurstallar. Studien tar upp RAS som Àr ett recirkulerande odlingssystem för fisk och passar bra inomhus. Eftersom vattnet renas och ÄteranvÀnds Àr det ett system som inte krÀver mer vattenresurser Àn nödvÀndigt. RAS Àr ett system som Àr anpassningsbart efter den fisk som produceras, dÄ vattenmiljön kan styras. Vid fiskodling Àr det viktigt att ha koll pÄ vilken miljö som passar fisken. De flesta fiskar klarar relativt stor temperaturvariation, men har ett smalare temperaturspektrum för optimal tillvÀxt. Syre Àr en mycket viktig faktor och mÄste finnas och oftast tillföras sÄ att det finns tillgÀngligt syre i tillrÀcklig mÀngd för att fisken ska mÄ bra. Studien jÀmför skillnader och likheter med att odla varm- respektive kallvattenfisk. Arterna som tas upp som exempel Àr niltilapia (Oreochromis niloticus) och röding (Salvelinus alpinus). BÄda arterna Àr efterfrÄgade hos svenska konsumenter, men röding Àr nÄgot vanligare dÄ den avlats i Sverige under lÀngre tid. Röding har en högre slaktvikt Àn tilapia, men nÄr den under lÀngre uppfödningstid. Foderomvandlingsfaktorn Àr nÄgot bÀttre hos röding Àn tilapia. Tilapia Àr en omnivor fisk och har god tillvÀxt pÄ ett helt vegetabiliskt foder. Röding Àr en karnivor fisk och stÀller högre krav pÄ fodrets proteininnehÄll. Fiskarterna har generellt ganska lika preferenser nÀr det kommer till vattenkvalité, förutom temperatur och syrehalt, dÀr det Àr en markant skillnad. Niltilapa krÀver varmt vatten, runt 30 C, för optimal tillvÀxt medan röding föredrar kallt vatten, runt 10 C. Avelsarbete finns hos bÄda arterna och har snabbt gjort stora skillnader inom produktionen. BÄde tilapia och röding har blivit billigare att producera och vÀxer snabbare nu jÀmfört med tidigare generationer av arterna.The reason why the study was conducted is the increasing need for protein for human consumption, combined with an increased number of empty animal stables. The study addresses RAS, which is a recirculating farming system for fish farming and fits well indoors. Since the water is purified and reused, it is a system that does not require more water resources than necessary. RAS is a system that is adaptable to the fish to be produced, when the aquatic environment can be strictly controlled. When farming fish, it is important to keep track of which environment suits the fish. Most fish can withstand relatively large temperature variation but have a narrower temperature spectrum for optimal growth. Oxygen is a very important factor and must be present and usually supplied so that there is enough sufficient oxygen available for the fish to feel good. The study compares differences and similarities with growing hot and cold-water fish respectively. The species covered as examples are niltilapia (Oreochromis niloticus) and Atlantic charr (Salvelinus alpinus). Both species are in demand from Swedish consumers, but Atlantic charr is more common since it has been bred in Sweden for a longer time. Atlantic char has a higher slaughter weight than tilapia but reaches it after a longer breeding time. The feed conversion factor is slightly better in char than tilapia. Tilapia is an omnivorous fish and has good growth on a whole vegetable feed. Atlantic charr is a carnivorous fish and places higher demands on the protein content of the feed. Fish species generally have quite similar preferences when it comes to water quality, except temperature and oxygen content, where there is a marked difference. Niltilapa requires warm water, around 30 °C, for optimal growth while charr prefers cold water, around 10 °C. Breeding work is found in both species and has in a quite short time made large differences on the production. Both tilapia and charr have become cheaper to produce and are growing faster now compared to previous generations of species

    Pancreatic exocrine insufficiency after bariatric surgery

    Get PDF
    Morbid obesity is a lifelong disease, and all patients require complementary follow-up including nutritional surveillance by a multidisciplinary team after bariatric procedures. Pancreatic exocrine insufficiency (PEI) refers to an insufficient secretion of pancreatic enzymes and/or sodium bicarbonate. PEI is a known multifactorial complication after upper gastrointestinal surgery, and might constitute an important clinical problem due to the large number of bariatric surgical procedures in the world. Symptoms of PEI often overlap with sequelae of gastric bypass, making the diagnosis difficult. Steatorrhea, weight loss, maldigestion and malabsorption are pathognomonic for both clinical conditions. Altered anatomy after bypass surgery can make the diagnostic process even more difficult. Fecal elastase-1 (FE1) is a useful diagnostic test. PEI should be considered in all patients after bariatric surgery with prolonged gastrointestinal complaints that are suggestive of maldigestion and/or malabsorption. Appropriate pancreatic enzyme replacement therapy should be part of the treatment algorithm in patients with confirmed PEI or symptoms suggestive of this complication

    Pig behaviour during crowding

    Get PDF
    Rearing in organic pig production differs from conventional rearing; pigs have outdoor access and larger space allowances. Regardless of production system all pigs are transported before slaughter and during transport pigs are crowded together in a new environment and in a space smaller than they are used to. As pigs in organic herds are reared at even larger space allowances than conventional pigs, such crowding could possibly have a stronger impact on pig behaviour and well-being. Six pig producing herds, three conventional and three organic, were visited and pigs from each herd were enclosed during 12 minutes in a test area corresponding to the crowding on a transport vehicle. During the crowding, pigs‟ behaviour was observed, before and after enclosure in the test area skin lesion scores were recorded, and also measures of heart girth (for weight estimation) was done. The results show that there are differences in how organic and conventional pigs‟ response to a crowded situation. Pigs in organic herds were more active, i.e. standing up (p=0.004), only pigs in conventional herds lied down during the test period. Moreover, organic pigs were more engaged in social tactile interactions (0.001>pp<0,006), vokaliserade mer (p=0,002) och klĂ€ttrade betydligt mer pĂ„ vĂ€ggarna till testomrĂ„det (p<0,001) jĂ€mfört med de konventionella grisarna. Grisarna i de konventionella besĂ€ttningarna hade mer hudskador Ă€n de ekologiska innan studien (p=0,013), men ingen skillnad i förĂ€ndring efter studien kunde urskiljas. De intervjuade transportörerna upplevde skillnader i beteende mellan ekologiska och konventionella grisar, de ansĂ„g att ekologiska grisar var mer rörliga och stirriga. Huruvida detta ansĂ„gs vara positivt eller negativt för deras arbete upplevdes olika. Sammanfattningsvis, grisar i ekologiska besĂ€ttningar vokaliserade mer, var mer aktiva och utförde mer sociala interaktioner vid trĂ€ngsel pĂ„ en liten yta jĂ€mfört med grisar i konventionella besĂ€ttningar. Detta skulle kunna tyda pĂ„ att grisar frĂ„n ekologiska besĂ€ttningar kan ha svĂ„rare, Ă€n grisar frĂ„n konventionella besĂ€ttningar, att hantera trĂ€ngsel pĂ„ en liten yta
