Regulators to hear comments today on eel management plan

 

The American eel along the Atlantic coastal areas is being reviewed by the Atlantic States Marine Fisheries  Commission to take public comments on a draft addendum from the Interstate Fishery Management Plan for the American Eel.  

The plan is for both commercial and recreational management options for yellow, glass – including elvers, and silver eels, it also calls to increase the monitoring for fisheries by state and outline methods to improve the habitat.  

Members of the Passamaquoddy tribe and  Gov. Paul LePage are expected to comment on the new elver licensing rules. The Passamaquoddy tribe has been issued more licenses than is allotted and the state is refusing to accept the additional licenses which has brought new problems facing the Legislation. It’s illegal to take elvers, and it has been switched from being a civil offense to becoming a criminal offense, which passed in April. The fine is $2,000, potential seizure of gear, and possibly jail time. The Maine Marine Patrol has issued summonses for members of the Passamaqouddy tribe who licenses that are over the state designated number.  

The draft addendum is in response to a declining population of American eels from 2012 reports, the eels have been slowly decling for decades and have been depleting in Atlantic waters. The main reasons for the  depletion of the American eels is caused by overfishing, habitat loss, turbine mortality, climate change impacts –  rising temperatures and acidification — in the ocean and changes to the web of sea life.

 

I think that if there has been a noticeable decrease in the American eel population for decades the Atlantic States Marine Fisheries Commission should have put new regulations into order a long time ago. Though the eels may not be endangered the population should be at sustainable levels if they’re going to continue to be harvested.

Basic fish management principles ignored

KRSA-Logo04                      The Kenai River king salmon are the largest salmon in the world,  drawing worldwide interest  of all sport fishers. In recent news the conservation and fishery management regulations have been called in to  question discussing whether or not they are allowing overfishing of these world record fish.  The Kenai River Sportfishing Association (KRSA) released their concerns on the “hard times with historic low returns” of these king salmon.

             The Alaska Department of Fish and Game (ADFG) has already set preseason restrictions and closures because there is a low king salmon abundance.

                In reaction to these new restrictions the  Kenai River Sportfishing Association (KRSA) spoke out about the  principles  fishery  management  are not being met, and that “Human history shows our nature wanting to test the line between fishing and overfishing – and far too often we roll the dice in favor of short-term profits only to see another fish stock run aground.” –  Ricky Gease, Executive Director of Kenai River Sportfishing Association (KRSA).

               The problem that the KRSA is seeing with the current fishery management is the lack of conservation of the King Salmon – They recently have made it public their views on the management conducted by  former Alaska Board of Fisheries (BOF) member Vince Webster.

“Our concerns regarding Webster’s confirmation spotlighted the fact that basic principles of fishery management were not being followed. These included his failed leadership to provide adequate board oversight regarding an alarmingly low new interim escapement goal for Kenai kings, which drops by one third the minimum number of king spawners from 18,000 to 12,000 (Didson sonar counts); his advocacy to set an optimum escapement goal even lower than the new minimum so that commercial set netters could keep on fishing; and, his failed attempt to shift the burden of king conservation solely onto one user group, the personal use fishery, when no other group faced restrictions. These and other similar past actions added to the foundation and argument that he should no longer serve on the board.”

          They also direct blame towards the  Alaska Department of Fish and Game (ADFG) stating,

“It rushed a new interim escapement goal for Kenai kings at a strikingly low escapement level without adequate peer review. Contrary to professional and standard department protocols, ADFG lowered the new range so much so that two-thirds of the new goal has no escapement data to support it”  

        This was an extremely interesting article to read, I feel that it was very bias in the sense that they directly placed blame on a certain person and department. I think that instead of specifically placing blame they could have discussed the problems they think are  occurring  with the low return of the king salmon and what could be fixed to increase king salmon abundance and decrease overfishing. I do agree that if they are seeing problems with the return of the king salmon and overfishing they should be addressed accordingly.

Federal council adopts options for ocean salmon sport fisheries

Source:  https://wdfw.wa.gov/news/mar1213a/

wdfw_logo_03-15-11Chinook_Salmon_SpawningCoho_Salmon_SpawningThe Washington Department of  Fish  and Wildlife and  Phil Anderson the WDFW Director have  came up with 3 options to help prepare for a forecast of a lower abundance of Columbia River  Chinook and a higher abundance of  Columbia  River Coho.  The  Pacific Fishery Management Council (PFMC)   will be approving one of these options sometime in April, the options will set up parameters for the state and tribal fishery managers for this years fishing seasons.

  • Option 1  — 51,500 chinook and 75,600 coho.

Option 1 would have a strict daily limit of two salmon in all areas, and would have to release all coho and wild chinook. Some marine areas would be able to fish for two salmon but can only keep one chinook. Fisheries would close earlier than the set end date if a coastline quota of 8,000 hatchery  chinooks was met.

  • Option 2  — 41,500 chinook and 71,400 coho

Option 2 would also have a strict daily limit of two salmon in all areas, and would have to release all coho and wild chinook. Anglers who fished all four marine areas would be able to retain one chinook of the two salmon daily limit, and those fishing in two specific marine areas would be allowed to retain an additional two salmon.

  • Option 3  — 30,000 chinook and 63,000 coho.

Anglers who fished in all four marine areas would be allowed one chinook as part of the two salmon daily limit. In two specific marine areas anglers would also be allowed an additional two pink salmon.

Each option would have designated days of fishing and a specific set of dates for a season that will vary differently for each option, all the options have a different set of dates for the fishing season. The PFMW has multiple scheduled meetings to discuss the options, future forecasts and fisherie issues.

Using Amount of Fish Caught as Measure of Fisheries Health is Misleading

Overview : The article consists of the argument that you cannot effectively estimate the health of fisheries solely based on the estimate of how many fish are hauled in each year. It’s part of a “point/counterpoint” commentary between Ray Hilborn & Trevor Branch of the University of Washington and countered by Daniel Pauly of the  University  of British Columbia.  

  • They based their arguments of the data that was published by the Food and Agriculture Organization of the United Nations.
  • The majority of the argument is that the number of fish that are being caught doesn’t directly reflect the number of fish in the sea, there are multiple factors that could skew the numbers of the catch that they aren’t taking into consideration.
  • The rebuttal argument is that a more accurate method is to use stock assessments separating fishery by fishery and region by region – then from those surveys and data calculate the health.
  • A factor that goes into both arguments is the price of stock assessment compared to the price of catch data. Daniel Pauly argues that the cost of stock assessments that are around $50,000 – millions will be hard for “resource-starved  governments in developing countries” and Hilborn and Branch rebuttal saying that it will be hard work and take multiple people/departments to make it work but the benefits would out weight the costs.

 

I think that both arguments have some valid points, I think that the catch data being used by some fisheries might give somewhat of a skew on numbers but it doesn’t mean  that it is a completely flawed system. I think that the stock assessments might be a more “innovated” method to measure the health of the fisheries, but later on in the article they discuss if catch data is all you have to go on that it is still effective if the researchers use it tentatively. I don’t know enough about either method to give a strong opinion but based on what I have read from the article I think that from the information given by Ray Hilborn and Trevor Branch that catch data is only accurate 1/3 of the time stock assessment would be the better method to assess the health of a fisheries, but because of the high cost I think that if you could innovate catch data to be a more accurate method to measure it then it’d make more sense to do that in the future.

Mandarin Fish

   1.mandarinfish

Scientific  Name : Pterosynchiropus splendidus

Nicknames :  Mandarin Dragonet, Mandarin Goby, Green Mandarinfish, Stripped Mandarinfish,  Psychedelic fish

Size : They’re a small species only reaching about 3 inches in length

mandarin fish1

Reproduction :  Females will group together at the reef and seek for males. The males then begin to court the females, the bigger and stronger males are more likely to be chosen. Males also can reproduce with multiple females in a night. The male and female pair attach at the pelvic fin and swim to the top of the reef where they release the eggs and sperm in a cloud (about 200 eggs). The fertilized eggs take 18-24 hours to hatch into larvae, then after two weeks they settle into the reef.

Trophic Status :  In the wild & in fish tanks they are very picky eaters. They eat mainly small worms, protozoans, and small crustaceans.

Habitat Preferences :  In the wild they can be found in sandy bottoms between reef crests around  Malaysia, Indonesia, the  Philippines, and Australia. But they’ve also become a popular tank fish, so they can be also be found in households around the world.

Enemies & Friends :  Mandarins secrete a mucous from their skin,  which  helps repel predators. Also their bright coloration is taken by  predators  that they may be toxic.  Scorpion fish  are one of their most known predators. Mandarin fish are very skiddish and shy, so they prefer to avoid other fish.

Interests :  

  • Mandarins don’t have scales! Instead they have a thick protective coat of mucous that covers their body which makes them resistant to Ick and other parasites.  
  • Mandarins picky eating habits make them very difficult to handle in fish tank situations.
  • Mandarin fish can range in price from $15 – $100. With shipping and tax being the most expensive part of purchase.
  • Mandarin fishes life spans are four times longer in the wild than captive.

Quotes :  Melissa King  of Ventura, CA “Beautiful and great fish. Will “dance” at night, if you have a mated pair. Must have LOTS of copepods to eat. Consider having a refugium or well stocked sump if you get this fish. Once that little belly starts to look sunken, it may be too late!”
