News to implement sharks protection by CITES

List of species of sharks and rays protection. Photo by CITES.
Several species of sharks and rays have been threatened by fisheries and the strong market of shark fins around the world. But now great news happened last month to protect the sharks and rays! The Convention on International Trade in Endangered Species of Wild Flora and Fauna (CITES) focused on start stronger protection on more five species of sharks and two species of manta rays. This international convention is strong and with several stakeholders and policy makers they will began a direct control on fisheries landings and also the marketing of shark fins. Recently people of many signatory countries are being trained to identify the five species of sharks through their shark fins and now control and punished the countries and people who had fished these species.

The Giant Clams: a scientific new inspiring new technologies


Giant Clam (Tridcna crocea) in Great Barrier (Australia) - Photo by Simone Marques
Do you already ask how this amazing marine species of mollusk produce this beautiful color in their tissue? Recently researchers of University of Santa Barbara (CA) discovery how visiting some special places of Pacific Ocean and testing in some species of Giant Clams with different colors in their tissues. First this wonderful color was provide by algae that use their interior clam as a house and also make this awesome color by a symbiosis with the clan by the photosynthesis. This symbiosis results on energy back to the clams. But the great challenge for this research was discovery how these algae inside of the clams capture the sun light for this symbiosis. They describe that this species presenting iridescent cells with ability to keep solar energy hiding in their shells and also with spectacular capacity to illuminate millions of cells of symbiotic algae that live inside. This discovery impressed the science to think about and inspiring in new technologies for solar energies for humankind.

Coral's fish crushing raises conservation dilemma



Parrotfish Species from Great Reef - Photo by Simone Marques

Parrotfish species are considered a key species in several communities of reef ecosystems promoting balance mainly by the coral polyps as their preferencial food. In last 20 years the hard exploitation mainly from artisanal fisheries have declined several species of parrotfishes in reef ecosystems around tropical regions. 

Actually several studies from this reef fishes species have shown feeding behavior and their main function in reefs ecosystems. To know more about this interesting reef fishes and how they feed on coral reefs click on the link bellow, enjoy and share with your friends.

The harsh reality of fisheries



Artisanal Fisheries in the Northeast of Brazil - Photo by Simone Marques

"Most seafood eaters know the sad story of the Atlantic cod. The ill effects of the postwar buildup of industrialized American fishing are epitomized by that fish’s overexploitation: Gorton’s fish sticks and McDonald’s Filets-o-Fish all once rode on the backs of billions of cod. The codfish populations of North America plummeted and have yet to return."

"...According to the National Marine Fisheries Service, even though the United States controls more ocean than any other country, 86 percent of the seafood we consume is imported."

"...most wild Atlantic salmon populations have been fished to commercial extinction, and today a majority of our lox comes from selectively bred farmed salmon, with Chile our largest supplier."

"To make things triply strange, a portion of that salmon, after heading across the Pacific, returns to us: Because foreign labor is so cheap, many Alaskan salmon are caught in American waters, frozen, defrosted in Asia, filleted and boned, refrozen and sent back to us. Pollock also make this Asian round trip, as do squid — and who knows what else?"

"We can have no more intimate relationship with our environment than to eat from it."

These texts above were copied from a great report about where the fish that you eat come from, written by PAUL GREENBERG. 

After read this  terrific report about fisheries, the reality in my country is not so different. Really we don't know nothing about where the fishes and other marine organisms (lobsters, slumps, shrimps) that we eat come from and what's happen after the fisheries in the foreign trade. In these days all of us living in busy way, and we never stop to thinking about what we are eating and where this animal, fruit, vegetal come from. And how are the population of each species from marine ecosystem that humanity like and consume since they begun to explore?

In Brazil several products from fisheries are exported and we don't know what will make with this fishes in the other countries. Is a "swap"? In the other pathway several fisheries products are imported and we think this a good product produced by other country as salmon, Kani and others products used in Japanese and Chinese food for example. 

Now is time to think about it and look for where this food come from, how they were fished and where they were produced. Our country should have the rules and legislation in each food that you consume and how they are produced. You as a citizen could be informed better and try to consume more natural products from the coastal and marine ecosystems produces by our own country.

Climate change is great matter of concern. During the last decades many changes and forecasts about climate change, global heating, rising sea level, ocean acidification have been recorded. So it was and is happening or this will happen independent about the human impacts in the natural environments?

Most of forecasts of climate change sounds that the human impacts are accelerating the effects of global heating, rising sea level and negative impacts on the coastal and marine ecosystems. The IPCC (Intergovernamental Painel on Climate Change) also make forecasts with several projects and researches with great expertise in climate change showing what will happen in the next 40 years in our oceans and earth surface. Every forecast is true?

Threats for coral reefs

Bleach Coral (Millepora brasiliensis) - Photo by Simone Marques
Do you knew why coral reefs can loss their colour?

Coral reefs are so fragile and due the increase temperature of the ocean and also the increase of carbon dioxide. These physical and chemical water changes promote negative changes in the life cycle of coral reefs and first the corals losing their beautiful and varied colours to white colour and second they became vulnerable to diseases by bacterias and virus as well die by increase of algae growing over the reef.

This bleaching phenomenon in coral reefs have happened in last 10 years fasten than we can imagine reducing the biodiversity in their communities mainly among the coastal ecosystems from tropical regions. Several researches have studied this bleaching process in coral reef trying to find solutions to avoid it.

One of the main solutions is so close to human diary life... who lives near to the beaches and coastal regions may have attention on the amount of water used, the garbage, waste and the drain and efluents produced day by day..

The ghost of marine ecosystems


Figure representing the effects of marine debris - Image by Google Images


The main impacts in marine ecosystems are the marine debris by human waste caused by lack of conscience or attention with the garbage produced day by day.

Fisheries as a important livelihood and water services for many coastal communities also have brought a lot of problems to seabed. Recent studies have showed that several kind of fishing gear which are abandoned or lost over the sea have been compared as a dangerous ghost that have threatened and killed many species of fishes, turtles, seabirds and cetaceans.

Your worry and behave can change the sea life and protected them in their natural habitats.The next time that you'll go to the beach and get in to the water think and help us to save our marine ecosystems only collecting your garbage and telling your friends about this consciousness.

Take care of sealion

Sealion Otaria flavescens - Photo by Google Images


The sealion Otaria flavescens is a huge marine mammal whom eat some fishes in cold water of south America. Some years ago some fishers thinking this species is a guilt for stealing the most of fishes during the fisheries. But recent studies showed the otherwise where this amazing species eat some smaller fishes during their swimming and this fishes are not target for the fisherman. Now many environmental education about the biology of this sealion species is being made with the local communities and mainly with the fishermen.

Coral Reefs Decline

After many years of human degradation in our marine ecosystems through pollution, overfishing and human occupation along to coast regions, coral reefs have declined.
Around last 40 years of coral reef studies and  monitoring in tropical regions several key species of this ecosystems reduced by overfishing and during this period the coral reef beginning to die... pollution arise at coast region and coral reefs beginning to die... many reef fish species beginning to disappear and going toward to local extintion..

We are having several notices about the traffic of shark fins around the world mainly to satisfy the oriental culture of shark fins soups. Many environmental agencies are worried about this practice and have tried to reduce this action through manifestations among temperate and tropical coastal regions where shark populations have declined. Shark species became vulnerable mainly by the late maturation and fishing exploitation. Now we have to read and to generate huge conscience to defend this wonderful fishes and apex predators of our oceans.

Alien fish species


Photos by Google Images


Do you have know about alien or exotic species?
Alien or exotic species are non native species that could be animals, plants or other organism which may cause several damages into the ecosystems and became a plague harming the economy and affecting the human health.
In marine ecosystems many species of invertebrates, fishes and algae could be non native and the human activities as aquarium trade, ballast water and others have brought these non native species.
One example of most recent alien among reef fishes is the lion fish from Family Scorpaenidae (e.g. Pterois volitans) in Caribbean sea. This alien reef fish was registered in Atlantic Ocean in 1985 near Dania Florida. Also the lion fish invasion was record in a accidental realize of some lion fish from aquarium during Hurricane Andrew, Walter Courtney that was quoted in 2010 where was saying he would like to "put this idea to rest".
Today this invasive species is dominating most of reefs of Atlantic Ocean, Caribbean sea and Gulf of Mexico with some records for South Atlantic. The main problem of this beautiful and dangerous species for Atlantic ocean is that this fish has a great capacity of reproduction, is a top predator of fishes and invertebrates and don't have predator for this species. The biological strategies of this invasive species have caused several damages to reef ecosystems reducing coral cover and native reef fishes.

Possible solution to marine debris





Photos by Google Images

Is possible reduce the marine debris into the oceans?
Many species of marine birds, turtles, marine mammals and other marine organisms could mistake plastic debris with food and die in few days. Some younglets of marine birds also could affect by plastic debris in a single moment when their mothers take the food by her throat. So if this food contain any kind of plastic debris, this indefensible younglet  could die in hours. Another examples of plastic debris occur with marine turtles who confuse their preferential food with plastic debris floating and have showed several deaths around coastline of the oceans.
Recently, a young ducth of only 19 years old, Boyan Slat, create one of the possible solutions to reduce the marine debris, mainly plastic debris, into the oceans. He proposed a solution to clean half of the Pacific Ocean in 10 years. The project's Slat consist in a floating barrier which take advantage of oceanic currents making a trench that blocks the debris floating in the waters.

Marine Protected Area is a great tool to protect marine species




Coral Reefs in MPA Costa dos Corais - Brazil

Since the huge advance of protected area around the world in last 20 years ago, scientists have studied how protected area have restored and keep save threatened species. In marine ecosystems most of marine protected areas (MPAs) are proposed to restored target species in fisheries and also most of them are classified as sustainable use. Although many studies show that MPAs of integral protection restored fished species (eg. fishes, invertebrates) some researchers who study the cycle life said this tool is not enough. Beyond the implementation of MPA is necessary selected essencial habitat for juvenile phase (nurseries) and adult phase (shallow to deep habitat) because many species needs estuaries, mangroves, shallow reefs, sea gram in their early life and deep reef or rock reef in adult phase. This two kinds of essencial habitat is also called connectivity. Actually the MPAs may design this essential habitat to protect all life cycle of species tho preserve and restore the connectivity of species. This new concept have been discuss in last years to better design the effectiveness of any kind of MPA. Now we don't thinking only to protect target and threatened species but their life cycle and essential habitat that they need.

Recent studies of MPAs have analyzed how MPAs have effective for marine species in the 2 main kinds of Protected Area (PA): sustainable use and integral protection. Click in two links bellow and read the recent papers related with MPAs of Brazil. Enjoy!

Can coral reefs survive to global heating?



Coral species from Great Barrier Reef in Australia

This is a paramount question to answer nowadays, in the next 20 to 30 years to future generations about healthy and survive of coral reefs. Coral reefs are the most import aquatic ecosystem of the world that maintain higher biodiversity and keep a lot of resources to humankind. In last 30 years many coral species have been suffer with the sped up of global climate change and the consequences of global heating. The global heating bias to cause the coral bleaching in many species of coral and have changing the symbiosis tolerance with the zooxantelas and corals. Many species also became vulnerable to diseases going to death and future colonization by algae. However, some studies have showed some hopes about the resistance of coral reefs to thermal stress. Some experiments with Acropora species have indicated acclimatization of the coral species to thermal stress suggesting a physiological plasticity of the host (corals) and symbiotic components (bacterias and zooxantelas) playing an important role in response to ocean warming.

As a soup of plastic debris floating around our oceans... it's so sad to see most of debris produced by us going down to ocean and promote dangerous of aquatic ecosystems and species as marine turtles making mistakes with plastic debris as their preferential food is really a jellyfish. Most of this animals having suffering with this debris in our marine ecosystem and don't survive. This is not restricted about turtles but reaches marine birds, fishes, whales, dolphins and other marine organism that use or make mistake of their preferencial foods or refuges in their marine habitat. Also fisheries promote a lot of debris with fishnets and hooks where a lot of marine animals as birds, marine mammals and turtles can stay arrested and die.
