Marine protected area Marine protected areas (MPA) are protected areas of seas, oceans, estuaries or in the US, the Great Lakes .[2] These marine areas can come in many forms ranging from wildlife refuges to research facilities.[3] MPAs restrict human activity for a conservation purpose, typically to protect natural or cultural resources.[4] Such marine resources are protected by local, state, territorial, native, regional, national, or international authorities and differ substantially among and between nations. This variation includes different limitations on development, fishing practices, fishing seasons and catch limits, moorings and bans on removing or disrupting marine life. In some situations (such as with the Phoenix Islands Protected Area), MPAs also provide revenue for countries, potentially equal to the income that they would have if they were to grant companies permissions to fish.[5]
On 28 October 2016 in Hobart, Australia, the Convention for the Conservation of Antarctic Marine Living Resources agreed to establish the first Antarctic and largest marine protected area in the world encompassing 1.55 million km2 (600,000 sq mi) in the Ross Sea.[6] Other large MPAs are in the Indian, Pacific, and Atlantic Oceans, in certain exclusive economic zones of Australia and overseas territories of France, the United Kingdom and the United States, with major (990,000 square kilometres (380,000 sq mi) or larger) new or expanded MPAs by these nations since 2012—such as Natural Park of the Coral Sea, Pacific Remote Islands Marine National Monument, Coral Sea Commonwealth Marine Reserve and South Georgia and the South Sandwich Islands Marine Protected Area. When counted with MPAs of all sizes from many other countries, as of August 2016 there are more than 13,650 MPAs, encompassing 2.07% of the world's oceans, with half of that area – encompassing 1.03% of the world's oceans – receiving complete "no-take" designation.[7]
Eco-Friendly Fishing Lures: One of the best ways to practice sustainable fishing is to use biodegradable fishing lures. Since rubber doesn’t break down, in the water or in a fish’s stomach, a good substitute is biodegradable plastic that will dissolve over time. An added perk to these eco-friendly options is that the soft lures can be made in all colors and designs to attract your target fish just as effectively as traditional lures.
Eco Fishing Weights: Not only is lead toxic to humans, but it’s dangerous for fish as well, causing both physical and behavioral changes. That’s why many manufacturers today produce sinkers made from safer materials that will cause less damage if ingested or left in the water. Some common substitutes used in non-toxic weights are brass, steel, tungsten or tin. You’ll also want to make sure they’re chip resistant to prevent paint loss in the water. And remember that while these variations may be a little more expensive than lead lures, the benefits outweigh the costs.
Eco Fishing Line: Like lures, anglers today can opt for biodegradable monofilament line fishing line that breaks down faster yet still has the same performance characteristics as regular line. Even if you don’t have biodegradable line, you can take steps to properly dispose of your traditional line to reduce your impact on the environment. For example, many bait shops, fishing access points, piers and other spots have designated collection bins for discarded monofilament and fluorocarbon fishing line.
Other Eco Fishing Tackle and Equipment: Anglers have several other eco-friendly options nowadays. For example, when you’re choosing hooks, opt for circle hooks instead of J-hooks to minimize internal damage if you’re practicing catch and release. Look for rigs made of materials like glass beads. Pick knotless nets. Instead of using fresh bait collected from fish habitats, choose artificial. And when you’re picking out other gear like waders, bags or boxes, look for those made from recycled materials.
ECO-FRIENDLY ANGLING
Beyond fishing gear, there are other ways to practice eco-friendly fishing. If you catch and release, in addition to choosing barbless circle hooks, be sure to use the right eco-friendly fishing lures for the species to avoid exhausting the fish, keep your catch wet and limit the time the fish stays out of the water to increase the chance of survival.
It’s also important to pay attention to the area around you. Take your trash with you to prevent fish and other wildlife from eating or getting caught in your rubbish. If you’re boating, consider rowing or paddling a canoe rather than a motorized choice. If you do go in a power boat, be careful when you’re navigating over fragile habitats and be careful to prevent fuel spills.
A presentation to study the origin and development of oceanographic science in details from the ancient peoples to the modern period. This presentation will be very much helpful for the learners of this discipline.

A fish aggregating device is a man-made object used to attract ocean going pelagic fish such as marlin, tuna and mahi-mahi. They usually consist of buoys or floats tethered to the ocean floor with concrete blocks. FADs attract fish for numerous reasons that vary by species.
Fisheries aggregating devices (FADs) are human-made structures anchored offshore that attract fish, making them easier to catch so you can have a great fishing experience.
Climate Change: Implications for Fisheries and AquacultureECFoundation
The Fifth Assessment Report from the Intergovernmental Panel on Climate Change is the
most comprehensive and relevant analysis of our
changing climate. It provides the scientific fact base that will be used around the world to formulate climate policies in the coming years.
This document is one of a series synthesizing the most pertinent findings
of AR5 for specific economic and business sectors. It was born of the belief
that the fisheries and aquaculture sector could make more use of AR5, which is long and
highly technical, if it were distilled into an accurate, accessible, timely,
relevant and readable summary. Although the information presented here is a ‘translation’ of the key content relevant to this sector from AR5, this summary report adheres to the rigorous scientific basis of the original source material.
Grateful thanks are extended to all reviewers from both the science and
business communities for their time, effort and invaluable feedback on
this document. The basis for information presented in this overview report can be found
in the fully-referenced and peer-reviewed IPCC technical and scientific
background reports at: www.ipcc.ch

En esta presentación se habla del tema de la Biología Marina, contiene información sobre el que es, cual es su importancia, que estudia, sus objetivos y entre otras cosas.
Estos trabajo son principalmente para aquellos amigos y amigas que estudian a nivel universitario, o que simplemente quieren ver algo de información con un esquema mucho mas visible y fácil de comprender
La mycoplasmosis aviar es una enfermedad contagiosa de las aves causada por bacterias del género Mycoplasma. Esencialmente, afecta a aves como pollos, pavos y otras aves de corral, causando importantes pérdidas económicas en la industria avícola debido a la disminución en la producción de huevos y carne, así como a la mortalidad.
2. JUSTIFICACIÓN TÉCNICA
Yo elegí este tema por que es algo que me llama la atención ya que esta es la
profesión a la que me quiero dedicar.
El fondo en donde se encuentra el titulo es de color azul ya que el azul representa
el mar, y las letras son amarillas por el color de las esponjas o musgos y resalta
muy bien en el fondo azul.
También escogí esas imágenes por que son biólogos marinos trabajando, la letra
y su tamaño son Arial Black y tamaño 18 por que son letras grande su gruesas
para su mejor comprensión.
3. PRESENTACIÓN
Yo me enfoque en este tema de gran importancia, igual hablare de diversos temas
englobados en la Biología marina como son ¿Qué es la biología marina?, ¿Quiénes
se dedican a estudiar esto?, y cuales han sido su aportes a la vida.
4. LA BIOLOGÍA MARINA
La Biología Marina es una rama de la Biología que se encarga del estudio de los
estudia los seres vivos que habitan los ecosistemas marinos. Los océanos cubren
el 75% de la corteza terrestre. Incluye desde el plancton microscópico, hasta
cetáceos como las ballenas. Se estima que sólo se ha investigado, hasta ahora,
un 5% de la vida en los océanos.
5. PARA QUE SIRVE LA BIOLOGIA
MARINA
Se enfoca principalmente en educar sobre los paradigmas de la Biología Marina,
entre los que se encuentra, el impactos que provoca el hombre en el medio
oceánico y el manejo de recursos marinos, además de los componentes bióticos y
abióticos y su interacción y el efecto que provoca en la adaptación de las
especies.
6. OCEANOS
Grandes volúmenes de agua de la Tierra, los cuales poseen la mayor parte líquida
del planeta. Hasta hace poco se pensaba que se habían formado hace unos 4000
millones de años; Los océanos cubren el 71 % de la superficie de la Tierra, siendo
el Pacífico el mayor de todos.
Subdivisiones:
Antártico, Atlántico,
Ártico, Índico, Pacífico
7. MARES
Un mar es una masa de agua salada de tamaño menor que el océano, así como también el
conjunto de la masa de agua salada que cubre la mayor parte de la superficie del planeta
Tierra, incluyendo océanos y mares menores.
Mares litorales
Los mares litorales o costeros pueden ser considerados como golfos, muy grandes y
ampliamente abiertos, de los océanos. No están separados de éstos por ningún umbral
submarino; no obstante se distinguen de ellos por ser, en promedio, menos profundos, por
la mayor amplitud de las mareas y la temperatura más elevada de sus aguas
Mares epicontinental
Es el que se asienta sobre una plataforma continental con su lecho submarino a una
profundidad media de 200 m o menos; ejemplos de este tipo son el mar del Norte, o el
mar Argentino. Durante el punto máximo de las glaciaciones, los mares epicontinentales
desaparecen, pasando a ser solo llanuras de los continentes aledaños.
Mares continentales
Los mares continentales, entre los cuales destaca el mar Mediterráneo, deben su nombre
al hecho de hallarse enteramente situados dentro de los continentes, aunque
comunicados con los océanos por un estrecho cuya escasa profundidad crea un umbral
que dificulta los intercambios.

Los mares continentales, entre los cuales destaca el mar Mediterráneo,
deben su nombre al hecho de hallarse enteramente situados dentro de
los continentes, aunque comunicados con los océanos por un estrecho
cuya escasa profundidad crea un umbral que dificulta los intercambios;
éstos se producen, no obstante, en forma de corrientes de compensación
y de descarga
Mares cerrados
Los mares cerrados o interiores suelen ocupar extensas depresiones
endorreicas. Corresponden a lagos muy grandes, de agua más o menos
salada, entre los cuales destacan el mar Muerto, el mar Caspio y el mar
de Aral.

9. BAHIAS
Una bahía es una entrada a un mar, océano o lago, rodeada por tierra excepto por
una apertura, que suele ser más ancha que el resto de la penetración en tierra
adentro. Es decir, una concavidad en la línea costera formada por los
movimientos del mar o del lago.
10. FAUNA MARINA
En esta se encuentra diferentes tipos de animales, pero se dividen en diferentes
grupos que son los cetáceos el número total se desconoce ya que continúan
descubriéndose nuevas especies de delfines, zifios y ballenas. Además, la
información disponible sobre su estado de conservación a nivel mundial abarca
menos de la mitad de las especies.

n Los corales tienen un crecimiento muy lento (unos pocos milímetros por año) y
constituyen un hábitat de gran valor ecológico para numerosas especies. Crean
estructuras calcáreas tridimensionales, lo que ofrece protección, alimentación y
áreas de reproducción para muchos animales
11. PERSONAS
En el estudió de la biología marina se encuentran diversas personas que se
encargan el estudio de este tema.
Biólogos marinos:
Los biólogos marinos son responsables de muchas tareas en los sectores de
pesca y acuicultura. Por ejemplo, trabajan para la administración pública,
estimando y supervisando los diferentes stocks de animales que viven en el
océano. Muchos biólogos marinos trabajan como consultores, ofreciendo su
experiencia y conocimientos a otras compañías y organizaciones. Un biólogo
marino también puede trabajar con sistemas de vigilancia por satélite, analizando
y vendiendo los datos. Además, pueden trabajar como investigadores científicos
del medio marino.
12. Oceanógrafo marino:
Un oceanógrafo físico se preocupa de la investigación del océano asociada con los
fenómenos físicos a nivel tanto teórico como observacional, integrando información
satelital, in situ y de re-análisis, ésta última proveniente de modelos numéricos”.
Los procesos involucrados pueden ser cinemáticos, dinámicos o termodinámicos.
Físico:
Físico es el nombre común que se les da a los científicos y profesionales que se dedican al
área de las ciencias físicas o a actividades económicas relacionadas con la aplicación de
las mismas.
Históricamente, podría considerarse a Galileo Galilei como una de las primeras personas
cuyo perfil se ajusta al del físico moderno. Galileo fue uno de los primeros en estudiar las
cuestiones acerca del mundo material mediante el método científico.
