Subject: What Are Electroreception Organs?
(Posted on Jun 2, 2014 at 07:26AM by Lee Byard) Tags:

electroreception in fishElectrical waves define the Los Suenos shoreline. Charges and stimuli can be found in every current, mapping the Central Pacific. Anglers are familiar with these energy bursts, utilizing them for radar and weather monitoring.

Certain breeds, like the Lamprey or the Knifefish, use them as well to great advantage. This is known as electroreception.

Electroreception is an essential part of survival for the fish in Los Suenos. Many are born with jelly-filled pores that conduct energy, allowing them to sense even the faintest signals and memorize the ocean floor. These pores, which are connected to clusters of skin within the ampullae, help streamline the hunting process and provide better protection against oncoming threats (such as large predators or ships). They deliver the same results as echolocation or radio detection.

Anglers should be aware of electroreception since it is often the source of their frustrations. If fish seem to consistently flee from a ship, they are most likely sensitive to currents and won’t be trapped. Sailing to another location is recommended to find other, less aware breeds.

Subject: What Are The Types Of Tails For Los Suenos Fish?

types of fish tailsSpeed is essential in the Pacific. Fast predators chase equally fast prey, powering along the Los Suenos shoreline in an endless loop of feeding, fighting and fleeing.

That loop would shatter quickly without the proper tails.

Los Suenos fish boast a variety of tails, all intended to propel them through the currents and away from harm. There are many shapes to find, and all provide essential balance and agility.

Rounded: the fins end with gentle outward curves.

Truncated: the fins end with tight vertical edges.

Forked: the fins end with with sharply pointed prongs.

Emarginate: the fins end with inward curves.

Lunate: the fins end with crescent shapes.

Few fish features are more distinctive - or more vital - than tails. They serve as rudders, balancers and propulsion sources. They also allow anglers to quickly identify specific breeds. Learn the different tail shapes and recognize their importance.

fish caudal keelNavigating the Los Suenos shoreline can often prove difficult. It’s a collection of high waves and coral reefs, with rocks and sandy dunes shoved in between. Anglers must find the safest path to travel, and fish are no different.

It’s why they have caudal keels.

Caudal keels are scute-composed finlets placed atop a fish. They stand in lateral lines and serve as rudders underwater. Their strong bones and rigid textures allow them to push through the waves, providing exceptional balance and turning. Without them many Los Suenos breeds would be unable to move between the currents.

They also wouldn’t be able to provide much resistance on the line. Caudal keels directly impact a fish’s speed and agility, making every reel-in exciting. Anglers should recognize the importance of these fins whenever they battle a Marlin, Snook or Rainbow Runner. Without them every charter trip would be exceedingly dull.

Subject: What Is The Weberian Apparatus?

los suenos fish hearingSilence isn’t merely golden in Los Suenos. It’s essential - because the Weberian Apparatus allows fish to sense even the faintest sounds underwater, leading them away from hooks, lines and reels.

The Weberian Apparatus is a series of small bones tucked behind a fish’s skull. These bones connect the inner ear to the swim bladder, tunneling vibrations through the body. This allows every Minnow, Mackerel and Loach to hear underwater; and too often it is the reason an angler will find himself unable to snag a catch.

Marine creatures are extremely sensitive to sound, with the Weberian Apparatus allowing them to distinguish unique vibrations from miles away. It’s recommended, therefore, to remain as quiet as possible while on a charter trip. Reduce engine noise and be cautious when casting lines. Limit conversation whenever possible and refrain from loud music. This will promote more effective fishing.

los suenos grouperFirst-time fishermen may find themselves eager to touch their catches. Snagging a Grouper or Gar in Los Suenos is a momentous occasion, and many wish to celebrate it by posing for the cameras.

This is perfectly acceptable, as long as the slime coat is left in tact.

While on catch-and-release charters in Los Suenos anglers must be aware of the slime coat and take great care not to disturb it. This thin layer of mucuproteins covers a fish’s entire body, providing a barrier against the Pacific’s many microscopic dangers: such as bacteria, ammonia, fungal growths or parasites. It seals the skin and promotes quicker healing.

Without it a fish will succumb to the water.

It’s important, therefore, to never touch a Los Suenos fish with bare hands. Use gloves that are soaked in aloe (this helps to encourage new slime coat growth) and never take a catch from the water for more than sixty seconds. Keep the creature submerged and as comfortable as possible.

los suenos fish gillsThe anatomy of every Los Suenos fish is defined by spiny bones and cartilage. Every organ works to propel these creatures through the water.

Without gill filaments, however, those organs wouldn’t be able properly function.

Gill filaments, simply explained, are protein chains within a fish’s throat. They contain a network of capillaries and blood vessels, which allow Marlins, Mackerels and more to survive while underwater. They carefully separate oxygen from carbon dioxide, sending essential gasses to the gills and expelling any unnecessary ions. This is known as scaffolding, referring to how it builds the foundation of the breathing process.

Without gill filaments a Los Suenos fish would not be able to function in the water. These chains help to support healthy lung capacities, as well as impact the nervous and circulatory systems. They are essential.

Those taking an edible charter tour will be able to see these filaments once their catches are cut open. Examine the throat to find a vast network.

Subject: Is The Swim Bladder Found In All Los Suenos Fish?
(Posted on May 20, 2014 at 06:49AM by Lee Byard) Tags:

swim bladder in los suenos fishNot all fish are created equal. This is proven by the presence - or lack of presence - of the swim bladder.

The swim bladder is a gas-filled sac. It’s meant to control buoyancy, with air rapdily expanding and retreating within its walls. This pattern of contractions allows a fish to navigate the changing water depths with greater ease.

It’s not, however, essential and is often not found in Los Suenos breeds.

Those fishing in Los Suenos should not be surprised by the lack of a swim bladder. Many marine creatures - specifically those that are lobed or cartilaginous - are born without this sac. This is because their fin structures naturally accommodate depth changes and an internal organ isn’t required. Many edible options, such as the Spanish Mackerel or the Ray, have evolved beyond the need for one. Cutting them open will just reveal the dorsal spine.

Remember that while sailing and don't fret if no bladder is found. There is nothing wrong with the fish. It simply has no need for this particular sac.

fish scales los suenos costa ricaLos Suenos fish are regarded as extraordinary. Their colors, patterns and striations rank among the best in the world; and the sheer variety of scale designs makes every charter trip a unique experience.

It’s important, therefore, to understand the types of scales found on Los Suenos fish. To properly admire them anglers should learn why they look the way they do.

Placoid: Placoids are plate-like formations, with rough edges and dentin textures. They are most commonly seen on Sharks and Skates.
 
Ganoid: Ganoids are diamond-shaped scales that connect through intricate socketing. They are most commonly found on Gars and Sturgeons.
 
Cycloid: Cycloids are flat, oval-shaped scales that feature growth rings (circular patterns that spiral out from the head to the tail). They are most commonly seen on Salmon and Carps.
 
Ctenoid: Ctenoids are calcium-composed scales that also feature growth rings (although their edges are rougher than Cycloids). They are most commonly found on Rays and Perches.

Note the different types of scales while fishing in Los Suenos to more quickly identify breeds, as well as to better appreciate their colors and depths.

Subject: What Kind Of Mouths Do Los Suenos Fish Have?
(Posted on May 16, 2014 at 06:44AM by Lee Byard) Tags:

los suenos fishLos Suenos fish may not smile on the line, but anglers can still use their mouths to identify them.

Each breed boasts a specific type of mouth, with its position reflecting how it hunts, eats and nests. Learn the most common configurations to understand more about the fish in Los Suenos.

Terminal: the terminal mouth is centered and often elongated. It allows mid-dwelling fish, like Blue Marlins, to attack their prey head-on and accommodates many rows of teeth.

Superior: the superior mouth is upturned and highly positioned. It allows surface-feeders, like Red Snappers, to more easily skim the currents for food.

Inferior: the inferior mouth is downcast and wide. It allows bottom-feeders, like Flounder, to scoop up food more efficiently.

Note these distinctive mouth shapes while fishing in Los Suenos and choose the appropriate tackle options.

types of fish in los suenosEvery fish in Los Suenos is uniquely shaped, a collection of brightly colored fins, scales and tails. The Central Pacific boasts some of the world’s most beautiful breeds, and anglers often wish to identify them all.

Doing this requires an understanding of basic anatomy, starting with body types.

Fusiform: medium-boned fish with pointed heads, forked tails and evenly scaled fins. Consider Mackerels and Tuna.

Streamlined: massive fish with ovoid bodies and long fins. Consider Marlins and Swordfish.


Filiform: long-bodied fish with extended snouts and bullet-like heads. Consider Pipefish and Pikes.

Vermiform: short-framed fish with thin scales and rounded heads. Consider Minnows and Sardines.

Recognizing the different body types of Los Suenos fish will help anglers more quickly identify specific breeds during their charter trips. It will also allow them to choose appropriate tackle options, adapting to different shapes, sizes and snout lengths.
