When a fish smiles…

Lingcod (ophiodon elongatus) are almost primeval looking with large, gaping mouths and 18 large, sharp canine-like teeth. The term “ophiodon” means “snake-toothed.”

This fish was given the name ‘Lingcod’ because it looked a bit like both a ling and a cod fish. Not because it was either or even related. Lingcods belong to the greenling family (Hexagrammidae).

Description

Lingcod colors can vary. Photo courtesy of NOAA.

This voracious predator can grow to be 5 feet long and weigh up to around 130 pounds. Average size along the Oregon coast is around 2-3 feet (or around 5-10 years old).

The fish has a sinuous body with two successive long fins. They are typically dark gray, brown, or greenish on the back with some copper-colored mottling or spotting along the upper back, and sometimes blue.

Territory

Lingcods are native to the North American west coast from the Gulf of Alaska into Baja California, Mexico. Adults like to be near rocks, inshore up to 230-fathoms deep. Young lingcod prefer sandy or muddy bay bottoms and inshore areas.

As adults Lingcod are fairly sedentary and non-migratory. Males migrate to nearshore spawning grounds in late fall to establish and aggressively defend nest sites. Preferred sites have strong currents and are near rock crevices and ledges.

Spawning occurs in winter. Mature females leave the spawning ground after depositing the eggs.

Male Lingcods guard the nest until hatch (about 8- to 1-weeks later). Successful spawning would not be possible without this protection. Rockfish, sculpins, kelp greenlings, Sea Stars, and other cod will quickly destroy an unguarded nest.

Prey & Predators

Adults are aggressive predators that will eat just about anything they can fit into their large gaping mouths. Prey includes smaller lingcod, squid, octopi, crab, and large rock fish. Predators include sea lions and harbor seals, along with sharks and larger lingcod.

Fishing

Lingcods are prized by ocean sport and spear anglers, and have been an important part of local cultures.

Restrictions to protect habitat can involve seasons, areas, and equipment. Be sure to check Oregon Sport Fishing regulations and seasonal changes, licensing, and limits.

Lingcods harvested nearshore are often larger and tastier. Going out beyond the bay could be well worth the journey.

The smile…

Fish don’t smile. Mind the fingers…

What animal can be found in almost every state, and in northern Canada to southern Mexico?

A Deer Mouse

The deer mouse occurs as part of essentially all communities in North America below the treeline (high mountainous areas where trees do not grow). It has the broadest distribution of any species within the genus.

Characteristics

You may not see it in the wild very often. Why? Because it is active at night and a rather small mouse-like rodent.

You may however, see it in a research lab. Deer mice are used because they are easy to care for and keep themselves clean.

This mouse is only three to four inches full grown with a multicolored tail that may be four to five inches long. The colorings, tail length, and markings vary widely with the soft fur color ranging from brown to black. The white underside and feet are consistent. The mouse got the name “deer” because its color pattern was similar to that of a white-tailed deer.

Nesting

During the day the species spends a lot of time in trees a common nest location. They are excellent climbers and swimmers. They will also build soil burrows, use rock crevices, and a variety of other locations for their nests.

Nests are created using grasses, roots, mosses, wool, thistledown, etc.  They are often communal. Deer mouse litters are kept in separate, away from the communal nest.

These mice often stay in their original home range to reproduce. They are social, and will recognize and interact with mice that have overlapping ranges. Communications are chemical, visual, and vocal (such as shrieks, squeaks, trills, and drumming out a warning.

OCD-like Behavior

Movement is usually on foot walking or running. They will also leap when threatened. Limited movement leads to intrafamilial mating and limited gene flow within a range.

This may contribute to OCD-like behaviors that become evident by two months old. One behavior is creating overly large nests in the lab when not necessary.

Reproduction

This rodent reproduces profusely compared to other species and even to local mammals. Food availability, rather than season, will determined breeding opportunities.

It is not uncommon for female deer mice to have three or more litters per year. Captive deer mice have had as many as 14 litters in one year.

Mice reach adulthood at six weeks.

Diet

Deer mice are omnivores and will change their eating habits based on the season. This rodent heavily consumes arthropods such as spiders and caterpillars in the winter with seeds, insects in the spring, seeds, fruits, and leaves in the summer. They will also consume fungi.

Deer mice hoard their food and will store up to one pint of food in ground holes, tree cavities, and nests.

Predators

They are prey for almost everything like larger mammals, snakes, domestic pets, and birds. Deer mice are can carry viruses.

Disease Carrier

One particular virus to note is the Hanta. These rodents can carry the airborne hantavirus. Hanta can be passed to humans during clean up operations and through contaminated food.

Minimize the Risk

To minimize these rodents minimize potential nesting locations such as rock piles, firewood, and vegetation (especially vines connecting trees to attics) before cold weather hits. Close up any openings to your home. Get some help eradicating an infection.

Surf fishing is one of Oregon’s most underutilized fisheries.
There are plenty of places to fish and lots of fish to catch!

There are nine different species of surfperch found off the Oregon coast. The most popular surfperch is the Redtail.  It is popular because it is very tasty and frequently caught.

Redtails are found from Baja California northward up into Vancouver Island, British Columbia. Redtail surfperch are predominantly surf dwellers off sandy beaches.

Typically, they live in large schools in the surf zone about 30 feet from the shoreline (or between the second and fourth breaker row. They are attracted to the deeper holes and areas with high sand erosion.  

These fish concentrate just before spawning in the spring and early summer in sheltered waters such as estuaries and protected bay areas. Large numbers of these fish can be taken at this time. Oregon Dept. of Fish and Wildlife regulations are usually very generous and this fish can be released with minimal harm.  

Surfperch and Seaperch are sometimes confused. Seaperch live in kelp beds in deeper waters.

Identification

The Redtail Surfperch is a slim, oblong-shaped fish that is about twice as long as high and can weigh in at over three pounds and grow to around 16 inches long. The average size is about two pounds.

This silver to white fish has eight to eleven reddish brown vertical bars on the sides. The red or pink fins have both rays and spines, and the tail is moderately forked. Coloration can vary depending on the time of year (breeding season) and age of the fish.

Prey

Surfperch prefer small crustaceans and will also dine on small crabs, shrimp, mussels, and marine worms. Sand crabs; sand, kelp, and tube worms; or clam necks and mussels can be used for bait. They will also take a shrimp pattern fly off of a flyrod.

Breeding

Surfperch breed in the fall and give birth to live young between June to August. A female will typically birth an average of 27 miniature replicas of the adults. Maximum number of young can reach 51.

Harvest Techniques

Scout out potential fishing locations ahead of time during low tides. Look for steeply sloped beaches where the waves are breaking hard, rocky areas near sandy or jetties, and places where the shore cuts inward. The best time to fish is an hour or two before high tide.

Fishing gear can be rented if desired. If you have your own set up, choose a #4 or #6 hook and secure it 24-30 inches below a 1- to 2-ounce sinker on an 8- to 10-pound line.  Sturdy flyrods can also be used.

Enjoying them

These are tasty fish and taste similar to their distant cousins (rockfish, snapper, and sea bass). Recipes for the ‘cousins’ will work just fine for surfperch. Typically, the fish is grilled whole, crispy-fried, or steamed Asian style. Filleting anything less than two pounds will waste too much meat.

You can also find these fish in West Coast Asian markets all year long whole or scaled and gutted. They may be referred to by other common names such as rosy surf fish, redtail seaperch, porgie, or Oregon porgie.
