Often times, trout fishing guides will refer to a fish as either “he” or “she.” It is highly common for our customers to ask, “how do you know the sex of the fish?” We’re posting a couple images that may help you identify the sex of the fish you have caught.

Although it is very hard to identify the sex of a juvenile trout, adults (of all salmonids) display characteristics that make identification rather easy.

The image above is of a female rainbow trout (Oncorhynchus mykiss). Females typically have a rounded, softer “nose” or “snout” and typically have a smaller mouth.

The above image is of a male rainbow trout. The nose of the fish is much pointier and has a larger mouth. Also, the fish’s lower jaw has developed a “kipe” or a hooked lower jaw. Little is known as to the function of this feature. But, it is helpful in identifying the sex of the salmonid (pronounced [Sal-Mon-Id] or [ˈsælmənɪd]).

The color variations of the above illustrations are seasonal.  The female pictured above has typical rainbow trout coloration for most of the year.  Whereas the male displayed is colored more vibrantly which is characteristic of what a rainbow would look like during the spawn, which happens naturally in the Spring.

Rock Creek Anglers is excited to offer a week-long salt water fishing adventure to the Turneffe Atoll in Belize.  The trip will be hosted by both Clark Smyth and Paul Robertson (founder of Rock Creek Anglers and director of the Turneffe Atoll Trust).  The Turneffe Atoll is a beautifully balanced ecosystem with unspoiled coral reefs teeming with an impressive variety of marine life.  The Atoll offers some of the best and most diverse salt water flats fishing as well as world renowned SCUBA diving and snorkeling opportunities.

Dates:  October and November 2011

The Turneffe Flats Lodge is located 30 miles east of Belize City on the eastern side of the Turneffe Atoll.  Turneffe Flats is known as one of the world’s top flats fishing resorts combining a remarkable fishery with superior service.  However, Turneffe Flats is not only a fly fishing destination but a SCUBA diving and eco adventure resort as well.  Choose to wade the flats, dive the famous “Blue Hole”, snorkel a private reef or simply relax on the beach.

Spacious, air conditioned, ocean-front beach cabanas await your arrival.  You’ll enjoy the comforts of home in a beautiful, unspoiled tropical setting.  Three delicious meals highlighting fresh seafood, local produce, home-baked pastries and fresh squeezed juice are all included.  Meals are to please any appetite.  The chefs prepare a blend of American and Belizean dishes.

The Turneffe Flats is noted for it’s variety of saltwater fly-fishing.  Plentiful bonefish, tarpon, snook and permit make Turneffe Flats one of the rare spots in the world where you have a legitimate shot at a Grand Slam (all four species in a day).  In addition, Turneffe’s guides, Clark Smyth and Paul Robertson are all equipped with the necessary skills and proven teaching techniques to either introduce you to saltwater fly fishing or make you a better saltwater angler.  We want to make it easy and enjoyable for you to feel good about deciding to further yourself an an angler.

Packages vary based on your interest.  All rates are based on double occupancy and are posted here.  Please contact Clark Smyth or Paul Robertson (or call 888-945-3876) to arrange this exciting vacation or with any questions you may have.  We are both looking forward to an exciting tropical vacation with you in Belize in the fall of 2011.

Winter Trout Fishing in the northern Rocky Mountains is not for everyone. Rarely does the airtemp reach above 30 degrees, layers of clothing are a must and fingerless or fingered polypropylene gloves can be your best friend.  If there is any wind, the chill factor can be a bit irritating.  On a warm winter day (meaning the sun is out) the weather can be tolerable if the angler is prepared.  Winter fishing is for the dedicated angler who enjoys fishing and not necessarily catching, although the later is always our goal.

Generally, solitude, abundant wildlife, low and clear water is why the angler enjoys fishing in the “off season.”  Within the past week, we have seen deer, coyotes, elk, eagles, hawks and even the paw prints of a rather large cat.  Furthermore, a variety of waterfowl and other birds that choose to stick it out for the season seem to take interest in our somewhat crazed attempt to find a few trout.

Both air and water temperatures are a significant factor during the winter months.  If the water temperature is below 34 degrees, you might as well hang up your rod, and return home to tie flies.  Both the fish and the fisherman can end up so chilled that production slows to grinding halt.  However, while angling on a tail-water (like the Bighorn) in the winter one can find water temperatures consistently in the low 50′s – warm for both the fisherman and his quarry.  Trout will feed regularly and fight pretty hard in these conditions.  Not to mention, there’s always the potential for a winter hatch.

If the air tempeture is hovering around freezing, the wind chill created from casting can freeze the line to your guides every few casts.  Attempting to cast a fly line which has been essentially glued to your rod can be a frustrating struggle.  The effort involved in clearing the ice from ones guides can also proove an arduous task – not to mention the dampening of already cold fingers.  Then, to top it off, efforts to tie (or untie) knots becoms a lengthy, painstaking process.  In this “bloggers” opinion, not worth it.  However, if the air temp is above freezing and the winter sun is shining… cast away.

Tip:  Bring a can of cooking spray on a winter fishing trip.  Spray your guides with the oil, you’ll double the number of casts before the ice builds up.

The water on Rock Creek is rising.  Given our heavy snowpack this year, it will settle into fishable shape in 3 to 4 weeks. We’ll be fishing it when others are saying “too high.”  Anglers who “know how” generally do well during high water.  Obviously, catching fish on artificial flies in cloudy water is tougher because the fly fisher relies on the fish’s sense of sight to trigger a strike.  Fly-fishing the wrong way in high dirty water is simply an exercise in futility.  However, there are things to remember and tactics to try at this time of year that can increase your success.

High Water on Rock Creek

1. Fish on Cooler Days

Even though you are probably wishing for warm days about now, hot weather means that more snow melts and the rivers go up.  At this time of year try to fish on cooler days and you’ll find that the water won’t be as high as it might get on very warm days.  Also, consider fishing early in the morning before the snow really starts to melt and bring the rivers up.

2. Fish Downstream

Snowmelt will take a while to get downstream so fishing the lower reaches of rivers that are far away from the melting snow.  Even though warm air temperatures in the high country could be melting lots of snow by noon, if you are far downstream, you may have until 2 or 3 in the afternoon before the high water gets to you.

3. Fish Big Dark Fly Patterns

Big dark fly patterns are far more visible than other earthy colors that might blend in with the earth-tinged water.  Black Stonefly patterns and Wooly Buggers are among our favorites.

4. Fish Slow

Remember that melting snow is really cold and that fish are cold-blooded creatures that will not move as quickly in cold snowmelt waters.  We like to bounce big nymphs slowly along the bottom and dead drifting Buggers slowly is a good tactic.  Because of low visibility and the cold water temperature you need to get your flies close to the fish so fish methodically and cover all of the water you can.

5. Watch River Flows

Keep a close watch on river flow charts provided by the USGS and other services.  Find streams that are lower than others in your area compared to their normal rates of flow.  Fish eat a lot during runoff because so much food drifts with the high water and can yield great results. Be smart about when, where and how you fish at this time of year and you could be surprised.

A typical Wyoming "Hopper"

Grasshopper infestations have taken on mythic tones here on the arid prairie of northern Wyoming — they blanket highways, eat T-shirts off clotheslines and devour nearly every scrap of vegetation on area ranch land.  The myth may come closer to reality this summer than at any time in decades.

Not great news for the ranching community, but it’s hard not to get excited as trout anglers.

According to the USDA and a  federal survey of farm areas taken last fall found high numbers of adult grasshoppers in all parts of Wyoming. (See Image Below)

“They’re grass eaters,” said Chuck Evitt, a rancher near Buffalo.  “They’ll eat the leaves and leave the stem.  But if they’re thick enough, they’ll eat the stem too, you see.”

“When they’re really thick, people say they’ll eat T-shirts on a line,” he said as he recalled a time in the mid-1980s when the grasshoppers were so thick that you couldn’t put your hand on the shady side of a fence post without squashing one.

“In Wyoming and Montana, we may see some of the most severe grasshopper outbreaks that we’ve seen in nearly 30 years,” said Charles Brown, the national grasshopper suppression program manager at the U.S. Department of Agriculture’s Animal and Plant Health Inspection Service.

It seems a safe assumption that  swarming insects will flutter en masse into rivers like the Bighorn, Piney Creek and the Powder.  In other words, the trout don’t know it yet, but a veritable smorgasbord of protein is about to rain from the sky.  In fact, we’re already seeing hoppers popping along some Colorado rivers right now, months earlier than normal.

There is nothing better than watching the slow, deliberate rise of a trout eating a grasshopper fly.  If that’s something that floats your boat too, and you were thinking about a western fishing jaunt, Plan for July, August and September 2010.  It’s going to go off, maybe in epic proportions.

While most anglers spend time on the water when the weather is nice, all trout feed year-round.  If you choose to go fishing early in the season, remember these tips:

- The water is still cold so the fish will tend to reside in slower deeper water.

- The water is lower and clearer than usual, be sure to fish with smaller flies and lighter tippets.

Fish have time to study your fly in slow, clear water

-  We preach this all of the time but most fly anglers laugh at us: use a small pair of binoculars to scan the water.  You will be amazed at what you are missing without the glasses.  You will see things on the surface of the stream that will change the way you fish.

- As always, try and be sneaky – bright colors and lot’s of movement can be the difference between a great day and a frustrating one.

- Trout have a protective coating that covers their entire body.  Contacting trout with gloves, dry hands or clothes can be detrimental to the health of the fish.  The protective “slime” on all species of fish is their immune system – it protects them from pathogens in the water.  When handling any fish, first be sure to get your hands wet.  When your hands small “fishy” it is usually because you have some of the fish’s “slime” on your hands.  Again, handling fish with wet hands will eliminate the smells and ensure that your quarry is swimming away healthy.

Keeping the fish near the water ensures your hands will be wet

Spring has sprung in the Rocky Mountains and it’s the time of year that we all start thinking about fishing.  The fish don’t seem to remember last season and they don’t seem to mind that the weather isn’t quite perfect… yet.  Spring fishing can offer some of the best angling opportunities of the season.  This is the time of year that Rock Creek Angler’s guides start honing their skills and getting ready for the summer season.  It’s the time of year when the red wing blackbirds start making their nests on the riverbanks while they chat at one another with the all so familiar sound, a sound that is reminiscent of fishing.  It’s also the time of year when both rainbow and cutthroat trout are building their nests (also called redds).  Recognizing where trout spawn and ensuring those fish are unmolested and their redds are left alone is crucial to the sustainability of these fish.

This photo illustrates what a redd may look like.  Note the oval shaped lighter gravel on the river bottom.  This area is where a female (or hen) trout meticulously kicked away a layer of gravel and laid her eggs to be fertilized.  She then re-covered the area with a light layer of small gravel to protect her brood.  Obviously small rocks cannot harm trout eggs, but be assured an angler tromping around a stream can be devastating.  Always be aware of your surroundings when fishing, particularly in the Spring when one could unknowingly disturb and subsequently destroy future generations of trout.

It’s never too early to book a trip with a Rock Creek Angler’s guide.  The summer season is filling up quickly and we are expecting another banner year.  Last season’s ‘hopper hatch’ was spectacular and we’re anticipating more of the same in 2010.  Rock Creek Anglers has access to dozens of miles of rivers and streams that are not very well known – and we like it that way.  Many of these hidden treasures are managed so that they receive very little pressure and therefore, offer fantastic fishing.  You can be sure to get away from the crowds and cast to a multitude of native trout while experiencing breathtaking 
scenery and abundant wildlife.  Many of our private water destinations regularly produce trout in the 20 inch plus category.  Wyoming ranks tenth in total area in the U.S. with 97,818 square miles, it ranks fiftieth in population with 493,782 residents.  That is only 5.09 people per square mile of land – which to most Wyoming trout anglers is too crowded, so… We offer ultra-private fishing vacations for all ability levels and will steer you to some of the best trout fishing in the country while ensuring that you won’t encounter another angler unless you want them there.
