Desinfisering av fiskeutstyr og båt

Det finnes faktisk ting i vannet som ikke er fult så bra, og disse tingene vil man absolutt ikke frakte fra stedet de finnes og til et nytt sted. Eksempler er vasspest, krepsepest, Gyrodactylus salaris og ørekyte etc.

Planter og fiskearter som ørekyte er såpass synlige at man bør kunne se om de følger med på lasset når man flytter båten sitt fra ett vann og til det neste. Det er uansett en god regel å gi båt og henger en skikkelig vask når man skifter beite, høyytrykkspyling blåser av det meste. Selv om du ikke akkurat har vasspest dinglende fra hengern, er det svært sannsynlig at sporene deres følger med båten din når du tar den opp.

Noen ting kan være enda værre å se, og ikke blir det nødvendigvis borte under vask heller. Gyro og krepsepest er begge sykdommer som man absolutt ikke må spre noe sted, og her holder det ikke å vaske. Mattilsynet opererer med følgende alternativer for desinfeksjon av fiskeutstyr generelt:
  • Varm opp i minst en time til over 60 grader.
  • Tørk utstyret i minimum 20 grader i minimum to døgn.
  • Bruk desinfisering som Virkon-S.
Ved mindre du har en ekstra stor bastue tilgjengelig, kan det bli tøft å varme opp båt og henger til 60 grader eller mer. Det er neppe særlig bra rent teknisk heller.... Men i sommerhalvåret kan man absolutt få til en tørkeperiode på land, som er det alternativet jeg selv bruker mest. Når jeg for eksempel har fisket i Øyeren eller Vansjø, står båten på land i en periode før jeg setter den ut i Tyrifjorden igjen og omvendt. Pass også på at du har tiltet motoren din opp og ned et par ganger, så du er sikker på at alt kjølevannet har rent ut. Har du skroggjennomføringer bør de blåses rene for vann før du setter båten til tørk (bruk trykkluft på en bensinstasjon).

Virkon-S er sannsynligvis det beste alternativet, og jeg undres stadig over at ikke det står slikt utstyr klart ved alle landets båtslipper, særlig båtslipper ved vassdrag som har laks eller kreps. Samvirkelaget (Felleskjøpet) har dette middelet i pulverform, du blander det ut i vann og sprayer på.

Sist men ikke minst, man må selvfølgelig ALDRI flytte fisk fra ett vassdrag til et annet, eller forbi skiller som større fosser i det samme vassdraget. Dette bør virkelig være en selvfølge, men vi ser alikevel alt for mange eksempler på at arter som gjedde, ørekyte, mort, ørret, sørv og suter dukker opp i stadig nye vann. Hvor dum er det mulig å være?

What is the difference between Lowrance HDS and Lowrance Elite HDI

Ever since the Elite 7 HDI came on the market I have recived a lot of questions regarding the difference between the HDS-range and Elite HDI. In this article I will try to list most of the differences, seen from a keen anglers point of view. This also means looking at most of what Lowrance has to offer, but I'm sticking to models sold today and models I personally would recommend. The three main model-series, plus the newcomer Elite CHIRP. HDS Gen 2 , true multi function displays (MFD) with button-operation and screensize from 5" to 10,4". HDS Gen 2 Touch , true multi function displays (MFD) with touchscreens and screensize from 7" to 12". Elite HDI , "stand alone", ie not ment for networking besides VHF and AIS. Button-operation and screensize from 4,3" to 7". Elite CHIRP , as Elite HDI but with CHIRP-sonar and faster processor in adition. Screensize 5" and 7".   HDS Gen 2 Units from this series are seen while fishing

What is the difference between HDS Carbon and HDS Live?

Here we go again, a new generation of the Lowrance HDS. And with that Facebook and the different forums are flooded with questions referring to the difference between the new and the old. So what is the difference between Lowrance HDS Live and HDS Carbon?

What is the difference between HDS Gen 3 and HDS Carbon?

Whenever a completely new model or a rewamp of an existing model comes out, we get the same question: "What is the difference?" Lowrance HDS Carbon Previously I have written a few articles about the differences between some of the (now historic) Lowrance-models: What is the difference between Lowrance HDS and Lowrance Elite HDI? What is the difference between Lowrance HDS Gen 2 and HDS Gen 3? This time we will take a look at the difference between Lowrance HDS Gen 3 and the brand new Lowrance HDS Carbon that was released 15. december 2016. We will look at the technical stuff, and try to translate that into what it will mean when out on the water. Lowrance HDS Gen 3 HDS Carbon is actually the fifth version of the popular HDS-series. Before it came HDS Gen 1, HDS Gen 2, HDS Gen 2 Touch and HDS Gen 3. HDS Gen 2 Touch marked a new area of how Lowrance run their model-updates, since it was released shortly after HDS Gen 2 and the two lived alon

What is the difference between Lowrance HDS Gen 2 and HDS Gen 3?

The cyclus in which models change have become shorter and shorter. Is there any real difference between them anymore? When I started out in this game most people would say that their sonar should stay onboard for 8-10 years before they would even consider upgrading it. Everything with less then 5 years on it was considered "new". But as with all things containing a circuit-board, development has been ever accelerating and we are now down to a two or three year cycle between model-changes. I belive that this is to the consumers advantage, but is "the new" always better then "the old"? In most cases the answer to that question is "yes", but it`s up to you to decide if that difference is big enough for you to spend your hard earned cash. Technically it is easy to spot the differences, but whether you will notice it out on the water is a more subjective mather. In this article I will try to look behind the marketing, and point to the actual diff

What is the difference between Lowrance HDS Live and Elite Ti2?

Lowrance as a brand of marine electronis is well known to all anglers, but the differences within their range of different models seem to cause quite a few questions out there. Here we will try to outline the difference between Lowrance HDS Live (top end) and Lowrance Elite Ti2 (middle range). Lowrance Elite Ti2 vs Lowrance HDS Live (photo; lowrance.com) As usual, we will start with the tech and then try to translate those technical aspects to practical differences while out on the water. Hardware - housing, screen and connections. The screen and housing on Elite Ti2 is the same as on the previous Elite Ti, and again more or less the same as on HDS Gen 2 Touch. (The memorycard-door and mounting-bracket is different from HDS Gen 2 Touch.) This is by no means new stuff, and compared to the more advanced housing and screen on HDS Live, Elite Ti2 is starting to show its relative age. However, with that in mind it is worth noting that when looking at the competition, several of
