World Oceans Day

Oceans are often seen as the blood of our planet. Oceans flow over nearly three-quarters of the planet, providing 97% of the Earth’s water. Not only are oceans a home to an array of marine wildlife, they create a livable environment for land-bearing organisms like humans. Even though most people do not venture far beyond the coast, the open ocean produces a massive scope of goods and services that are a fundamental part of our health, economies, and even our weather.

Marine fisheries, shipping routes, oxygen, carbon dioxide sinks, temperature, weather control, and the water cycle are all provided by the ocean and are essential to a functioning world. Ocean-based businesses contribute more than $500 billion to the world’s economy and approximately half of the world’s population resides in the coastal zone. Oceans supply food, transportation, jobs, and products that aid in keeping people warm, safe, informed, and entertained. Around 90% of all trade between countries is carried by ship. If the ocean cannot produce it, it can at least transport the goods.

Tomorrow, June 8th, people from around the world will join together in celebration to honor, help protect, and conserve the world’s oceans. The theme for this year’s World Oceans Day is “Our Oceans, Our Future.” What a suiting theme! Regardless of our distance from the ocean, our lives are still highly affected by the health of Earth’s oceans. Oceans generate most of the oxygen that we breathe, provide food for us, regulate our climate, and clean the water that we drink. Without maintaining healthy oceans, our future will be affected dramatically.

Celebrate World Oceans Day by adopting the practice of appreciating our oceans through plastic pollution prevention and cleaning the ocean of marine litter. Take care of the oceans that give so much to us in return!

Louisiana’s Seafood Ecology

For centuries, Louisiana has had a prospering commercial seafood industry. The catching and selling of shrimp, crabs, oysters, alligator, fish, and crawfish have sustained the livelihood of many families.  As one of the country’s largest seafood suppliers, Louisiana contributes more than 850 million total pounds of high-quality seafood to restaurants and homes across the world each year.

Louisiana’s fisheries are an integral part of our economy through providing jobs, as well as income and tax revenue. One of every seventy jobs in Louisiana is related to the seafood industry. As a whole, this leaves an economic impact of over $2.4 billion annually for the state of Louisiana. For many of the industrious fishermen who work Louisiana’s waters, their craft of bringing the finest seafood to the plates of people around the world has been passed down for many generations.

What makes Louisiana waters so plentiful? The abundance of seafood caught and served around the world all starts with our estuaries. An estuary is an ecosystem commonly located where a river meets the sea. Estuaries are inhabited by an array of plant and animal species that have adapted to a mixture of fresh and salt water caused by tidal flow. This changing mixture makes estuaries a fertile region for a variety of marine life. Along with estuaries providing an abundance of seafood, they also provide access to recreational activities and breeding and migratory locations and shelter for fish and wildlife.

Did You Know?

  • 75% of the United States commercial sea catch comes from estuaries.
  • 37% of estuary marshes in the United States are in Louisiana.
  • Louisiana is the largest commercial fishery in the United States.
  • Louisiana estuaries comprise the seventh largest estuary in the world.

You can help maintain healthy estuaries by keeping your estuary area clean of trash and robust for our seafood industries, wildlife, vegetation, and others to enjoy! Louisiana’s seafood industry promotes innovations that protect our coastline and help keep our waters clean. When you select Louisiana seafood, you are supporting the lifestyle and environment Louisiana natives have depended on for centuries. As they say about Louisiana seafood, “know better, eat better.”

TVFWD Annual Inspection Meeting

The Teche-Vermilion Basin Project was included in the 1966 Flood Control Act after a 1961 study by Louisiana’s Department of Public Works showed deteriorating water quality and insufficient water in Bayou Vermilion and Bayou Teche. Ground water was threatened with contamination by salt water due to lack of flow of the Teche and Vermilion Bayous. The purpose of the project is to restore the flow of water to the Teche-Vermilion basin, improve water quality through the increased flow, and prevent salt water from entering the lower parts of the basin. The increased flow is also intended to restore the water supply available for agricultural and industrial needs before the protection levees were built. The state legislature created the Teche-Vermilion Freshwater District Board of Commissioners in 1969. The Board of Commissions was charged with responsibility for the maintenance and operations of the original project of the Army Corps of Engineers, as well as major replacements.

On October 21, CWPPRA staff attended the Teche-Vermilion Fresh Water District Annual Inspection Meeting at the Teche-Vermilion Pump Station in Krotz Springs, La. The meeting began with a welcome speech from Donald Sagrera, TVFWD Executive Director. Introductions of property possession parish commissioners were made beginning with Ed Sonnier, Lafayette Parish; Donald Segura, Iberia Parish; Tommy Thibodeaux, St. Martin Parish; Mike Detraz, Vermilion Parish; and Bradley Grimmett, St. Landry Parish. A positive inspections report was given by Darrel Pontiff of Louisiana Coastal Protection and Restoration Authority, as well as Ted Elts of U.S. Army Corps of Engineers. Ed Sonnier, TVFWD Chairman, introduced Lafayette Mayor-President Joel Robideaux, who was the event’s guest speaker. The presentation continued with recognition of TVFWD staff and sponsors given by Cecil Knott, Operations Supervisor, and Alex Lopresto, TVFWD Legal Advisor. TVFWD Executive Director Donald Sagrera ended the ceremony with closing remarks.

Plants of the Wetlands

Hydrilla

hydrillaPlants of the wetlands are generally known to be highly dependent upon specific conditions, such as salinity, proximity to water, and vegetation type.
While some plants are able to adapt to condition alterations, other species do not overcome change as well. However, a major threat to all wetland vegetation is hydrilla.

Hydrilla is a non-native, invasive aquatic plant that has staked its claim by out-competing native plants and obstructing waterways. Hydrilla is a submerged, perennial plant that prefers freshwater, but can tolerate up to 7% salinity. This aggressive plant is known for clogging waterways, impeding natural flow, affecting human use such as fishing and seafood harvest, and clogging intakes and municipal drinking water supplies. Hydrilla can take over an area quickly as a result of its ability to multiply rapidly using four different strategies. Regrowth of stem fragments containing at least one node into a new plant, tubers on rhizomes producing new tubers, leaf turions that settle into sediment and form a new plant, and seed dispersal are all methods of reproduction for hydrilla. Hydrilla can out-compete native plants by its ability to tolerate low and high nutrient conditions in addition to growing in low light environments. Hydrilla is also successful in out-competing other plants by growing at a rate of one inch per day until reaching the water’s surface, followed by branching out to form a mat of vegetation which blocks light to other plants.

In order to control the growth of hydrilla, salvinia weevils have been released into severely affected areas. The salvinia weevil lives exclusively on hydrilla as a food source, thus reducing growth rates to allow control of the plant. The Coastal Wetlands Planning, Protection, and Restoration Act is currently researching the best, most beneficial method of controlling and eradicating invasive plant species.

BVPA Visionary Water Symposium 2016

The Bayou Vermilion Preservation Association (BVPA) is an organization which creates awareness of our natural environment by providing education and outreach to the general community about ways to conserve, protect and enjoy the Bayou Vermilion Watershed. The BVPA hosts an annual festival to commemorate and celebrate the Vermilion River as a cherished working river which contributes to Lafayette and Vermilion parish by confluences of small bayous in St. Mary and St. Landry parish. The theme of BVPA’s 3rd Annual Water Weekend on the Vermilion was “Backyard to the Bayou” which included a visionary water symposium directed toward understanding your role as the general public in the preservation of the river.

This year, the BVPA worked toward answering the question on many resident’s minds-How can we best inform and involve the community in preserving the bayou? In an attempt to answer this question, the water symposium discussed opportunities and threats for the Bayou Vermilion by presenting a series of distinguished speakers. Speakers include Peter Mayeux, owner of All Seasons Nursery and Landscaping, who spoke on ideas for best management practices on an individual’s property, followed by Rusty Ruckstuhl, landscape architect with Grassroots Landscaping, who discussed ideas and concepts of homeowner water management irrigation and drainage.  Michael Cullen, landscape architect with Land Architecture, LLC.; Pamela Gonzales Grainger, landscape engineer with Macbad Engineers; as well as Jeff Foshee and Teddy Beaullieu, Southern Lifestyle Development, each discussed relevant topics of their field for considerations toward sustainable community development. John Lopez, Lake Pontchartrain Basin Foundation, and Brad Klamer, New Orleans Sewage and Water Board, each gave insight into current successful projects in their respective regions, followed by Donald Sagrera, Teche-Vermilion Water District; David Cheramie, Bayou Vermilion District; and Bess Foret, Lafayette Consolidated Government, who discussed management of the bayou. The 3rd annual visionary water symposium closed with a panel discussion including Bess Foret, Michael Cullen, Pamela Gonzales Grainger, and Daniel Didier, where views were exchanged on how to involve the community in preserving the Bayou Vermilion.

The Coastal Wetland Planning, Protection, and Restoration Act’s Public Outreach staff attended the symposium and distributed various informational publications to symposium attendees.

Male vs. Female

Can you tell the difference between a male and female blue crab?

la crab 4Louisiana, Maryland, Virginia, and North Carolina all share the title of largest blue crab fisheries in the world; Louisiana accounts for over half of all commercial harvest landings in the Gulf of Mexico. While the commercial harvest of the blue crab continues to rise, recreational crabbing popularity is also on a steady climb. Why? Blue crabs spend the majority of their late juvenile and adulthood in estuaries which are often closely located to an accessible shoreline, making blue crabs a delicious challenge to catch. Whether the blue crab is caught commercially or by recreation, there are two distinct methods to sex a blue crab.

la crabs

Located on the underside of the crab’s carapace is the abdomen which forms a different shape depending upon the gender of the crab. Females have a broad and rounded abdomen while the male abdomen resembles a narrow t-shape. Another distinguishable characteristic are the red tips of the female’s claws. The blue crab is one of the many aquatic species that rely heavily upon the safety and health of wetlands for survival.
