Lobo Marino vs Leon Marino (seawolf vs sealion)

Hi I was in Cabo Polonio, Uruguay this week. I watched the sea lions by the light house. Very interesting animal! Never saw them in the wild before. Really a great experience. I came across the sign there(attached picture), stating there was different species there: Lobo Marino and Leon Marino. Translation to sea wolf and sea lion respectively. It was hard for me to tell difference between animals as they seemed to be living together. I could see that some individuals seemed to have an upward pointing nose though. There is no wifi in Cabo Polonio, so now checking after getting back I find it hard to find any information about sea wolves? Can you clear it out for me: What is the difference and do they live together or what? Thank you in advance! Christoffer

Black gills on dungeness crab

I bought 3 dungeness crabs from a retailer in Pike Place Market last Saturday. When we went to clean them....2 of the 3 crab had TOTALLY black gills. Looked like old motor oil. The black went all the way down into the meat. These were crabs bought from Oregon Indian tribes..... since the commercial crabbing season won't open until 1/15/2018. What were these crabs eating? I threw the black ones out.

Ash Content of different Feeds

Where can I get a feed tested for ash content? I need to compare the ash content of different lots of brine shrimp cysts. Can you recommend a lab that can do this ? I also would like to know if there is a company that offers toll processing to irradiate fresh seafood to increase shelf life for third party producers?

Land crabs

We have a property in Jamaica where there are land crabs which dig into our lawn which creates a walking hazard. We have not found an effective pesticide yet that will work. Since we are by the sea, we need to be careful of any runoff which could affect the coral and fishes.

how to make seafood waste material as fertilizer & removing any plant harmful salts

I would like to know how to best utilize waste sea scallops/shrimps complete with clam like shells, prawn/shrimp & unwanted offal & damaged fleshy bits.As all these materials complete with seawater are combined in the disposed waste, I need to know how to best prepare this waste into a usable fertilizer and not have any salts in the finished product that will harm the plants when applied.
I am open to a dry or wet end product.
There is a heat treatment method for an end dry product & some wet treatments.
Do either display more benefits for better plant growth?
Currently the quantity I have access to in its raw state is equivalent to approx 4-6 tonnes per week.
I am in Australia.
Also can I bulk it up with other materials to end up with more of the final product to sell?
