Chesapeake Bay: Nature of the Estuary, A Field Guide by Christopher P.All contents are copyright © Long & Foster Real Estate, Inc.Life in the Chesapeake Bay by Alice Jane Lippson and Robert L.The Chesapeake Bay blue crab population has not been overfished since female-specific management was implemented in 2008.Blue crabs are one of the most important commercial and recreational catches in the Chesapeake Bay.Male blue crabs are known as “jimmies,” while mature females are called "sooks.".The blue crab’s scientific name comes from the Greek words for “beautiful” and “swimmer.”.Few blue crabs live longer than three years. Immature crabs molt several times before they reach maturity, about 12 to 18 months after hatching. Megalopae eventually metamorphose into immature crabs, which look like tiny adults. Megalopae are pushed back into the estuary by wind and tidal currents, settling in key nursery habitats such as seagrass beds and marsh fringes. During their last larval molt, zoea metamorphose into a post-larval form called the megalopa. After four to eight weeks of development in the coastal ocean, the zoea return to the brackish waters of the Bay. After about two weeks, larvae are released near the mouth of the Bay.Ĭurrents transport the blue crab larvae, called zoea, out into the coastal waters, where they molt several times as they grow. The egg mass darkens as the developing larvae consume the orange yolk. Each bright orange egg mass may contain between 750,000 and two million eggs. Males eventually leave to search for another mate, while females migrate to the saltier waters of the lower Bay.Īs they migrate toward the mouth of the Bay, females develop an external egg mass, or sponge, beneath their aprons. After mating, the male continues to cradle the female until her shell hardens. ![]() Prior to mating, males will cradle a soft-shelled female in their legs, carrying her for several days while he searches for a protected area for her final molt. Reproduction and Life Cycleīlue crabs mate from May through October in the brackish waters of the Chesapeake Bay. Predatory birds, such as blue herons, and sea turtles are also known to feed on smaller crabs. ![]() Predatorsīlue crab predators include large fish like striped bass, Atlantic croaker and red drum. They will even eat more vulnerable soft-shelled blue crabs and small juveniles. Feedingīlue crabs will feed on nearly anything they can find, including clams, oysters, mussels, smaller crustaceans, freshly dead fish, and plant and animal detritus. Mature females have a broad, rounded apron, and immature females have a triangular apron. Males have a strongly tapered abdomen, or "apron," that resembles an inverted T. Its claws are bright blue, and those of mature females feature red tips.īlue crabs have three pairs of walking legs and paddle-shaped rear swimming legs. The carapace has nine marginal teeth on each side the ninth teeth are strong spines. The blue crab's carapace (shell) varies in color from bluish to olive green, and can reach up to 9 inches across.

![]() Dredge already feels like one of this year’s greatest indie horrors and all this, from a fishing game of all things. Basically, I'm completely enraptured, hook, line, sinker. Its eldritch world keeps pulling me back with its mystery and malevolent horror, and its sense of atmosphere and tension is incredible. I’ve spent hours exploring its murky waters and my constant shock at what unsettling creatures my hook brings in is seemingly never-ending. Black Salt Games' sinister fishing RPG is gripping and enchanting in a way I didn’t anticipate. I’ve not been playing Dredge long, but I’m calling it one of my favourite games of the year, right now, in February.

Pretty much every business – large and small – will need to provide their turnover at some point or another.įor instance, if you start building a business insurance quote with Superscript, we’ll ask you for your annual turnover so we can work out the right level of cover for you. Gross profit is your total sales minus the cost of goods or services sold (COGS), while net profit is sales minus COGS and expenses such as taxes and wages. While both turnover and profit look at your total sales, profit also includes some important deductions that aren’t considered when measuring turnover. It’s important to note that turnover isn’t the same as profit. What’s the difference between turnover and profit? If you're VAT-registered, make sure you exclude VAT when calculating turnover, as this sales tax technically belongs to HMRC rather than your business. If you provide services, such as consulting or labour, your turnover will be the total that you charged for these services.

And because it only considers income generated through your main trading activities, turnover doesn't take into account things like bank interest or money received from the sale of assets. Turnover is calculated over a specific period of time, usually a quarter or financial year. ![]() Put simply, turnover is the total amount of money your business receives from the sale of goods and services – minus discounts and VAT. The amounts derived from the provision of goods and services falling within the company's ordinary activities, after deduction of (a) trade discounts (b) value added tax, and (c) any other taxes based on the amounts so derived.

If managers are aware of these indicators, they can look out for them.
![]() say, the vertical edge at the left, it flares left and right and undergoes interference, producing the pattern along the left edge. ![]() ote the lines of maxima and minima that run approximately parallel to the edges, at both the inside edges of the blade and the outside edges. It also occurs when light passes an edge, suchĪs the edges of the razor blade why se diffraction pattern is shown in. As in Chapter 36, we must conclude that geometrical optics is only an approximation. Diffraction of light is not limited to situations of light passing through a narrow opening (such as a slit or pinhole). In between the maxima are minima.Such a pattern would be totally unexpected in geometrical optics: If light traveled in straight lines as rays, then the slit would allow some of those rays through and they would form a sharp, bright rendition of the slit on the viewing screen. This pattern consists of a broad and intense (very bright) central maximum and a number of narrower and less intense maxima (called secondary or side maxima) to both sides. Intercepted by a viewing screen, the light produces on the screen a diffraction pattern like that in Fig. For example, when monochromatic light from a distant source (or a laser) passes through a narrow slit and is then More than just flaring occurs, however, because the light produces an interference pattern called a dilTraction pattern. A method using the scattering of x rays by matter to study the structure of crystals.In Chapter 36 we defined diffraction rather loosely as the flaring of light as it emerges from a narrow slit. The distance between two consecutive crests or troughs in a wave. Alternating bands of light and dark that result from the mixing of two waves. Diffraction that occurs when the source and the observer are far from the diffraction aperture. A device used to produce diffraction patterns of materials. The wave pattern observed after a wave has passed through a diffracting aperture. The ultimate performance of an optical element such as a lens or mirror that depends only on the element's finite size. An equation that describes the diffraction of light from plane parallel surfaces. The diffraction pattern produced by a circular aperture such as a lens or a mirror. When optical instruments such as telescopes have no defects, the greatest detail they can observe is said to be diffraction limited. This indicates that the image of a star will always be widened by diffraction. The diffraction pattern of the telescope's circular mirror or lens is known as Airy's disk, which is seen as a bright central disk in the middle of a number of fainter rings. As an example of the latter, consider starlight entering a telescope. When both source and screen are far from the aperture, the term Fraunhofer diffraction is used. ![]() For example, an open window can cause sound waves to be diffracted through large angles.įresnel diffraction refers to the case when either the source or the screen are close to the aperture. With a large aperture most of the beam will pass straight through, with only the edges of the aperture causing diffraction, and there will be less "fuzziness." But if the size of the aperture is comparable to the wavelength, the diffraction pattern will widen. If both the source and the screen are far from the aperture the amount of "fuzziness" is determined by the wavelength of the source and the size of the aperture. The diffraction pattern will look something like the aperture (a slit, circle, square) but it will be surrounded by some diffracted waves that give it a "fuzzy" appearance. When a source of waves, such as a light bulb, sends a beam through an opening or aperture, a diffraction pattern will appear on a screen placed behind the aperture. Instead, there is a gray area along the edge that was created by light that was "bent" or diffracted at the side of the pole. But careful observation of the shadow's edge will reveal that the change from dark to light is not abrupt. From a distance the darkened zone of the shadow gives the impression that light traveling in a straight line from the Sun was blocked by the pole. Consider the shadow of a flagpole cast by the Sun on the ground. All waves are subject to diffraction when they encounter an obstacle in their path. |
