Cocahoe minnows are adapted to having their eggs exposed to both air and water due to rising and falling tides. This document is a description of how we imitate this behavior by using air incubation in the lab to produce and hatch larvae.
Production of cocahoe minnow eggs is achievable throughout late spring and fall months. Utilization of fertilized ponds has been successful in several southern coastal states.
Fish predators can cause considerable losses of fish produced in aquaculture. This document provides a list of the most common fish predators at aquaculture ponds.
When holding live baitfish, a number of factors must be managed properly to ensure good survival and health. Water quality, including parameters such as dissolved oxygen and temperature, is a very important factor to monitor while holding live baitfish.
Utilization of above-ground pools is practical for production of large numbers of cocahoe minnow eggs. This is achievable outdoors throughout summer, with peaks in late spring and early fall.
Cocahoe minnows require a minimal salinity to grow and thrive. The type of water you use and the type of salt can make a large difference in the survival and growth of these fish.
This fact sheet explores the economics behind different production scenarios showing which methods may be the most and least profitable.
Feeding is one of the most important factors in minnow production. This fact sheet addresses the best feeding practices to ensure growth and good health.
In order to raise and sell cocahoe minnows, there are several legal considerations. This fact sheet covers some of them.
There are a number of diseases and symptoms that cocahoe minnows can develop in a culture situation. This fact sheet addresses some of the more common issues that may be encountered.
A list of supplies and vendors for raising and spawning cocahoe minnows.
This fact sheet outlines some of the more common cocahoe culture systems.
Keeping fish healthy while hauling is very important for survival. Water quality is the most important factor to manage while hauling fish. This document describes how to manage water quality and haul fish safely.
Plug your own numbers into this Excel sheet to get relative estimate for different production scenarios. Disclaimer: the numbers generated are a rough estimate and interested parties should get in touch with the point of contact for a more detailed analysis.
A comprehensive guide to culturing cocahoe minnows. This manual covers topics including spawning, feeding, disease, water quality, best handling practices, production economics, vendor contact information and more.
Live baitfish for saltwater angling is typically a seasonally available commodity due to the reliance on wild-caught animals. Cultured cocahoe minnows could help supplement the wild-caught baitfish supply, thus serving as a viable revenue source for producers. Staff from the LSU AgCenter, in conjunction with Louisiana Sea Grant and the Louisiana Department of Wildlife and Fisheries, produced a survey for baitfish dealers. The following report is a summary of the responses from the survey.
The three main fish species raisedfor bait in the southern region are the golden shiner, the fathead minnow, and the goldfish. Together, these three species account for more than 90 percent of farm-raised bait and feeder fish sales in the United States.
The terms “baitfish” and “feeder fish” encompass a number of distinct species, each with its own nutritional requirements. Economic analyses clearly indicate that a feeding program is necessary for maximizing profit.
The high fish densities demanded by the market effectively reduce the availability of natural foods for individual fish. Thus, intensively cultured fish are generally fed prepared feeds to support maximum growth.
To be profitable, an aquaculture pond must be sited properly and designed for efficiency. An inaccessible location, leaks in the pond, poor seining conditions, or lack of good quality water will doom an aquaculture enterprise to failure.
Proper design and construction of ponds is critical to the success of a commercial catfish operation. Well-designed ponds, constructed on soil with proper clay content and adequate water supply, have a useful life of at least 10 years.
Considerable thought and planning should go into selecting sites for commercial fish production ponds. Construction costs, ease and cost of operation, and productivity can be greatly affected by the site selected.
