A legitimate concern is that reseeding the west side would bring additional harvest pressure that would make the reseeding a net loss. Better to let natural reseeding from remaining west side oysters and from drift fro the east side and from Sabine contribute. This will yield less localized oyster bars that are not so easily located and destroyed. In the meantime, one hopes that local oystering infrastructure will be largely dismantled and that ongoing local pressure will be more commensurate with naturally occurring supply. Reseeding just keeps the local harvest pressure up and begins to engender an entitlement mentality as if the government has taken the ability to earn a living away from people if the cycle of seeding and raping is not maintained. Plans to build a saltwater barrier at Calcasieu pass make seeding and conservation of oysters in the estuary a temporary proposition at best. |

Further, redfish do not have high levels of generational fidelity to one estuary (like seatrout), so a dip in body condition (and fecundity) in one estuary does not have the same impact. Also, the number of redfish eggs depends both on the population of mature females and the fecundity of each. Reduced average fecundity in one estuary is thus balanced by higher numbers of mature females and also by migration of eggs, larvae, and fish between estuaries. Redfish in other areas of Louisiana (Barataria, Terrebonne, Sabine) are not experiencing the same declines in body condition as the mature redfish in Calcasieu. |

MathGeek When is this likely to happen? I can't wait to go bass fishing in Turner's. |

Redfish population
Quote:
With numerous fishing reports of good catches, what are your thoughts of an estuary supporting x amount pounds of redfish similar to saying a freshwater lake supports a certain poundage of a particular species of fish ? |

The situation is further complicated by the openness of the system. There's a much greater flux of fish through the Calcasieu pass (plus the intracoastal waterway) than most freshwater lakes see to and from feeder streams. It is obvious to all that Louisiana inshore waters are among the most productive in the world in terms of seafood production per unit area. Very few freshwater lakes come anywhere close. Choices about commercial and recreational harvest limits and management are mostly about resource partitioning. If tons and tons of shrimp are harvested, there will be less for the specks and juvenile redfish to eat. At some point in crab harvest numbers, there is less for the redfish and drum to eat. Harvesting all the pogeys probably had an impact higher in the food chain. However, most of the time, seafood production is highest at lower trophic levels, so if it is marketable, it makes economic sense to harvest 1000 lbs of shrimp even if it means producing 100 lbs less of spotted seatrout. Oysters are different, however. The oysters are not only consumed by one species (black drum), oyster reefs provide essential hard bottom habitat and vertical relief to a whole array of benthic organisms. These benthic organisms contribute to ecosystem production in many ways. Further, the living oysters provide a variety of ecosystem services including improving water quality by filtering, serving as nurseries for fish, and buffering anthropogenic inputs. While it is hard to know the actual biomass of a species in an estuary, it is easy to infer how much of the species are present relative to their food supply. If (on average) the fish are fat, the food supply could support additional fish, or the fish are underpopulated relative to the available food. If the fish are thin (on average), there are too many fish for the available food supply, which could mean an over abundance of fish or an under abundance of their preferred forage species. The attached graph shows the relative condition factor for redfish in Calcasieu, analyzed by length class from 2011 to 2013. The statewide average is 100% based on analysis of large statewide data set measured from 1995 to 1999. Clearly, the adult redfish are having trouble finding sufficient forage to maintain body condition. The juveniles (16"-20") are doing better, but 2013 was the first year since 2011 that they were above the statewide average. A 2000 study (Jenkins 2004) found most fish sampled in Calcasieu were above the statewide body condition at about 103%. |

I think it's mainly from lack of menhaden and mullet. Once they get that big they mainly eat mullet poggie and crab. The little ones eat a lot of shrimp and small crab. 7-8 years ago I would see huge rafts of mullet in the lake. I don't see that too much any more. Occasionally but not like back in the day.

All this oyster dredging and a dozen of Raw is $15 everywhere in lake charles. This blows my mind, I get a dozen for $5 in Baton Rouge. Anyone have any idea why prices are so steep in lake charles?

Most oysters are harvested on the east side of the state. Less supply near LC.

Where are you getting them for 5 a dozen?

MG I thought gafftops primarily fed in the water column on live bait like trout do. Versus the hard heads that are bottom feeders and primarily eat dead. I know when I catch large gafftops it has been under a popping cork same as trout.

I've read several papers analyzing stomach contents, and while fish and shrimp are important parts of their diet, gafftops feed mainly on the bottom. Zoobenthos, benthic crustaceans, and crabs (mostly blue, but all kinds) make up the bulk of their diet. They have pharygeal teeth at the back of their throats that allow them to crush crabs, and thin shelled molluscs, but they probably cannot crush oysters. Gafftops can definitely be fast and agile predators when they need to be, but their long barbels give away that they prefer to slowly cruise the bottom and eat the bottom critters that their barbels detect in their wide swath. |

5 dollars a dozen at chimes east on coursey during happy hour. Everywhere in LC is $15 a dozen and I give them hell about it every time. Therefore, I wait for my trips to BR to endulge.

Check that out. Project ID 004.HR.06: "Salinity Control Structure in Calcasieu Ship Channel at Gulf of Mexico". This has been in the plans for a few years now. I do not believe they have set in stone when work will begin, but it is in the First Implementation Period (2012-2032). |

This will never happen in our life time, Do you know how many make a living off that lake and estuary!! Never will get approved ...NEVER

It didn't stop them from damming up almost all of the marsh drains on the East bank and arguably destroying the living of many small shrimpers. That happened in my lifetime. Never say never. I'm with you, hopefully we won't see it.

When it's time to put up the money, folks will make the case that it costs too much in terms of taxpayer money and negative economic impact. Future legislatures are never under any obligation to pay millions for hopes and intentions of past legislatures. Someone is also bound to ask whether a saltwater barrier of this size and scope (and cost) has ever been implemented before. Where? Was it completed on budget? Was it successful in its ecological goals? What was the economic impact? Did it have a negative impact on shipping? Did it have a negative impact on recreational uses? Did it have a negative impact on commercial fisheries? Once all the stakeholders have ample opportunity for input in a real funding and cost and risk analysis, it is unlikely to happen before 2032, unless someone can point to successful implementations in answer to the above questions. |
