Grok Questions:
- I have heard that there might be a correlation between cod and alewives, that cod might gather at the mouths of rivers for juvenile alewives, and they fatten up on them prior to spawning? is there anything to that story?
- Studies of cod show they have low length at age, weigh at age, fecundity, and recruitment. In addition, the forage base has a lot of low lipid components like invertebrates and crustaceans. Could they be related and would more high lipid forage fish like herring, mackerel and menhaden help?
- Atlantic cod fish, according to the NEFSC status of the ecosystem report, show low weight at age, low length at age, low fecundity and low recruitment. What could be the cause of that?
- What is the health condition of cod in the Gulf of Maine and Georges Bank?
- Is the cod food supply low in lipids?
- How has the energy content in the diet of cod in the gulf of maine and georges bank changed with the collapse of the herring, mackerel and menhaden populations?
- Please tell me about how cod change their diet as they reach spawning age
- What are the times of spawning of the different cod stocks in the northwest Atlantic fishery
- Has there ever been and food web analysis, like Wisconsin Bioenergetics or EwE that modeled the collapse of the Atlantic herring population in 1980 followed by the cod collapse in the 1990’s and specifically took into consideration the loss of the high lipid’s effect on cod biology, or anything close?
