ALASKA COMMERCIAL FISHERIES NEWS WITH FINS 6

ALASKA’S COMMERCIAL FISHERIES

 

How did Alaska manage the count on fish in the beginning?  Well they didn’t.  Congress had no idea where and/or how much fish was coming from any area.  In the 1890’s, the reports came from the canneries on how much was caught.  This was spread from Southeast to Bristol Bay. According to researcher’s Alaska kept better track of alcohol being shipped rather than the fish being shipped.  In 1905 they had the idea of dividing the information into regions.  This would give a better and accurate more estimate of how much and what was being caught.  Even though numbers were great no one was still managing the Alaska’s portion of fisheries.  William Thompson, a Harvard student, was hired on in 1927 to put some minds at ease using his statistics on why the areas had changed from previous years.  The catch was not as abundant and they had to travel further to get the same numbers.  In the 1950’s US Fish and Wildlife created a coding system that they used for the coast of Alaska. This system is still used today

In 1952, let’s just say Alaskans were not happy with the next outcome.  North Pacific Fisheries Convention was signed.  This gave the Japanese to fish for Salmon in the Bering Sea.  Knowing that this could and will affect Alaska’s number for salmon fishing, Congress thought the relationship with the Japanese was more important.  The only thing they agreed on was the catch numbers.  The INPFC created new areas which went by longitude and latitude to keep track of the estimates of fish that would affect Alaska.  Great history lesson for me was that in 1959 Alaska took statehood.  Finally some order or somewhat.  This meant Alaska was in control of its own fisheries.  Now with new technology and the work of ADF&G  we have better estimates and escapement numbers for our salmon fishing industry.

Massive Fish Kill News with fins #5

MASSIVE FISH KILL

Nova Scotia has been left puzzled.  During the last week in November, scientists and local people are stunned.  Numerous dead fish had washed up on the shore.  No one seems to know why all the dead Herring.  Many scientists have considered what may have caused it.  Could it be Climate change, human related or just mother nature.

In the beginning, they did consider climate change since the waters in this area are warming up faster every year, but again only speculation on an idea.  Many tests had been done to see if anything by people caused the mass kill.  They were tested for chemicals, disease, viral/bacterial, contaminants or poor quality of the water.

All the test came back negative.  No indication that man had anything to do with it.  Researchers then looked to the bottom of the sea floor.  There had been an earthquake in mid-December but again fish started showing up the last week in November. There was no signs of movement from fault lines, sulfide or emissions from pockmarks.  There was no evidence of mortality anywhere.

Still no answer has been determined.  Scientists and locals remained baffled.  They still have no answer on why such a large abundance of Herring washed up on shore.

ALASKA SALMON WITH ASIAN WATER TAPEWORM News with Fins 4

ALASKA SALMON WITH ASIAN WATER TAPEWORM

 

The first study and identification was done in 1986.  These tapeworms can only affect humans if eaten raw.  They have been found in chum, masu, pink and sockeye salmon.  There has been over 2,000 cases of people infected with the tapeworm but mostly in Asia.  With cases being reported, the Czech Science Foundation had researched 64 Alaska wild salmon (31 sockeyes, 23 pinks, 8 rainbow trout’s, 1 king and 1 Coho salmon).  After examining the salmon and trout numerous tapeworms were found that was 99 percent match to the Japanese broad tapeworm.

 How did this happen?  Well trickledown effect.  Infected birds poop out the eggs that goes into the water.  Those eggs turn into larvae and are eaten by small crustaceans known as copepods.  Then the copepods are eaten by the salmon.  Bingo we have an infected Alaska salmon full of tapeworms. 

 

I love eating salmon and I will make sure it is fully cooked before I touch it.  Fish and Game say for your own protection to cook the fish fully or freeze it before eating it to -4 to kill any parasitic worms.  They do not see this as a problem now but will keep on researching.  For those of you that like eating sushi and eat it in restaurants, they are supposed to freeze before they serve.  For my choice, I will just prefer to do it myself.

Climate Change Prompts Alaska Fish To Change Breeding Behavior News #3

Climate Change Prompts Alaska Fish To Change Breeding Behavior

   

According to researchers from the University of Washington, with climate change occurring breeding behaviors have changed.  The Three spine stickleback is one of the species that occupies lakes in the Bristol Bay Region.  The research was originally to capture information on Alaska’s sockeye salmon.  They started doing research in 1963 and continued to 2015.  This research was done to track the abundance of juvenile salmon in the freshwater lake of Aleknagik. 

Samples were taken along the lakeshore with nets every 7 days at 10 different sites from June until September.  While tracking the sockeye salmon, they also tracked all other species that was caught.  Three spine sticklebacks occupy the same space and feed on the same food that sockeye salmon do.  Sticklebacks usually only breed once a summer.  Findings in the captured nets show to different maturities which means, two different breeding times.  Alaska’s climate change in spring thaw is double to the climate change in different areas.  We know we are getting spring faster and the summers a little longer than normal.  Sticklebacks are now proved to be breeding twice in early spring during the thaw and then again in late summer.  Researchers do not know if this will be a problem now but foresee it will become a problem in the future. 

News with Fins #2 Ghost Shark

MYSTERIOUS GHOST SHARK FOUND FOR

1ST TIME IN NORTHERN HEMISPHERE

The Ghost shark is one of the craziest fish you will be lucky to view.  The deep sea living beauty looks like a shark but is actually considered part of the ratfish family.  This one above is called a pointy-nosed blue ratfish.  It’s given name is Hydrolagus trolli.  For most part they tend to live in the Southern Hemisphere 1 to 3 miles below the water’s surface.   The look of the ghost shark has a very unique look to it.  Honestly, it looks like it has no mouth but is completely stitched up.    They have sensory organs all over the body but especially in the mouth area.  This is used to sense movement and vibration in the water to locate food.  Another odd thing about the Ghost fish is the mating ritual.  The male has a sexual related organ on top of there head that helps position a female during mating.

They are extremely rare for sightings starting in 2002.  Yet now they are being seen more, but not for the first time in the Northern Hemisphere.  Scientists are not saying anything about migration.    All scientific information says that the ratfish have been around from 350 to 375 million years ago.  From the first sighting there has been 19 new ratfish species uncovered.  Researchers say there are probably many more to come.

WHAT AM I :  If you look at my picture, yes I am a little vain but I am a beautiful Lionfish.  I am one of 15 different species.(one and only) I am a pretty suttle fish.  I get along with everyone that is not trying to eat me.  I may look pretty but I have fooled a couple fish.  I am nice but can be quiet a threat to others.  I have spines on my back that are very venomous.  I only use them for protection and if threatened. I am not as vicious as our male species.  They seem to be more aggressive than us females.  Especially during mating season.  Which is all year round.  You could say they have permanent attitude.

 

NICKNAMES: Zebra fish, fire fish, turkey fish  dragon fish, scorpion fish and my favorite butterfly-cod. I have other names for which I am classified as but hard for me to even say it.  But here it is Pterois volitans.

 

WHERE I LIVE AND WHY:  I live in the South Pacific Ocean.  I have moved many times to find my perfect home.  I have lived in some lagoons and rocky areas.  I have claimed an area now in the coral reef.  It is beautiful and with the best scenery.  I see many other fish but not too many that look like me.  In my neighborhood the water is warm and the current is gentle.   I have been to many coral reefs and this one is my favorite until I feel like moving on.  The only thing I do not like from migrating is fighting for familiar territory.  I do tend to go to many other places as long as the water is warm and the current is cool.

FRIENDS:  I am a pretty open fish.  I consider everyone my friends especially in the reef area.  As long as they are not bigger than me and eat me I am okay.  Did swim next to a shark once but he almost hit me with his tale.

WHAT I LIKE TO EAT:  I like to eat baby lobsters, wrasses, parrotfish, blennies, shrimp and maybe anything that I can fit in my mouth.  I’ll try anything once.  I am to picky when I am hungry.

 

SEXUAL PREFERENCE:  I am interested in male lionfish.  I prefer not to stray.  What could be better than having babies that look exactly like me.  In my perspective,  as beautiful as I am I am not a one woman  one man type.  I am very promiscuous and prefer to experiment in my life.  I reach my maturity after a year of being born.  I reproduce a lot lol.  I can produce 2 egg sacks every four days.  I have had many children, my egg sacks can have up to 15,000 eggs.

MY INTERESTS:  My interests are not too interesting.  I like to gallivant during the day and hide out at night.  I mostly hang with myself.  I like the solitude.  Well at least till I see a hot male swimming around.  Then my interest may change.  I am pretty protective of my area though.  I have a route I take and I really don’t like anyone in my territory.

WHO THINKS I AM FOOD:  Interests in me not for my friendship would be sharks, groupers, really big eels, frogfish and had a run in with a scorpion fish but that didn’t end up to well.(for him)

For me I think we are all here for a reason whether we are predators or the food.  We are all here doing our own thing for reasons we know not.  Enjoy your life in the water you never know when it may end.     Lily the Lionfish

Fish Turn Off Genes to Adapt to Climate Change News with Fins #1

FISH TURN OFF GENES TO ADAPT TO CLIMATE CHANGE

Many different species have had to change their normal adaptation to survive.  Skates are one of the fish species that have had this change occur due to climate change.

 

Kingdom – Animalia    Class – Chondrichthyes        Order – Rajiformes      Family – Rajidae    Genus – Leucoraia

 

Skate is a cartilaginous species of fish found in the southern Gulf of St. Lawrence.  The skate has inhabited the area for over 7000 years.  Research has followed that the winter skate has been smaller than the previous years.  As researching had concluded, because of the shallowness from where they inhabit is why.  Becoming shallower the species has had to adapt to warmer climate.  Studies show that it is not a DNA change but a adaptation of using and expressing different genes.  This is a process called epigenetic changes – which basically means they are switching on and off parts of DNA with specified functions.  What is going to be necessary to use or not and this is all done within the fish.

It is not like physical change of appearance that would be considered alterations of the fish’s appearance.  This change makes the skate to be able to quickly adapt to an increase climate change.  This also is only occurring in species with longer life spans and low reproductively rates.

Introduction

Hello my name is Jami Creasey I have lived in Alaska off and on since 1985.  This place is amazing and that’s why I am still here.  Growing up in the community and raising my kids in a good environment. I am a single mom with 4 children and two jobs.  I love the outdoors and I am in the middle of working on my BA in Rural Development.  I thought since I live in Dillingham and we are part of a great seasonal fishing town it would be very interesting to take this class.
