Comment on "QUIZ: Can You Identify All 15 Of These Baby Fish?"
The Pictionary scene from "When Harry Met Sally" in which Bruno Kirby's character says, "Baby fish mouth."
Oily fish such as chunk-light tuna, sardines, halibut and salmon are the best sources of healthy omega-3's. But sardines aren't practical for feeding to a baby, and halibut and tuna are higher in mercury. That makes salmon the best source of DHA (again, the star omega-3 fatty acid) and, in my opinion, the healthiest fish for kids and adults alike. But almost all seafood contains omega-3's, so try giving your baby a variety of low-mercury fish. Pollock is used in most commercial fish sticks and is another good choice.
Except for shellfish, you can serve your baby puréed or mashed fish as early as 6 months when he starts eating solids. Fish may seem like a "grown-up" food, but it is the ideal fare for infants. Read on for serving ideas.
Bigger fish will eat baby guppies if they get the chance.
Newly hatched baby fish are called "fry."
Equipment: Baby Rearing Tanks Small Mating Tanks or Petri Dishes Liquid Fry and Paramecium Water Filtration System Water Purification Chemicals
Procedure: 0-7 days post-fertilization Zebrafish embryos should be raised for the first seven days in a shallow container (for example a petri dish or crossing tank). Do not feed the embryos/larva during this stage. They do not need food as they are still getting all of their nutrients from the yolk, and the added food will cause the water quality to decline and promote the growth of contaminants. When the larvae get their swim bladders, they are ready to be switched into a larger tank. Note that if the babies get put into a large/deep tank too early, they may have trouble obtaining the air they need to inflate their swim bladder. Finding a food that gives excellent survival of the larva during the first few weeks they are in a large tank can be challenging, and may take some experimentation. We have observed that zebrafish at all stages do better if their food floats at the air/water interface at the top of the tank. Here are some ideas: 1. Live paramecium (traditional and widely used food for baby zebrafish) downside-paramecium cultures can crash and/or become contaminated with other organisms that harm the fish-thus it is imperative to carefully monitor the quality of the paramecium cultures. 2. Liquid fry-we have stopped using this because it does not float, and it makes a horrible smelly mess on the bottom of the tank that seems to kill the small larvae 3. Our recent favorite: green powdered food that is composed of equal parts spirulina (dried algae) and Argent Chemical Laboratories Hatchfry Encapsulon Grade 0 (Aquac. Res. 37, 1107-1111). Separating it in a glass is a very bad idea because it's a little space for the little baby to swim around in. I would suggest buying a fish net for your baby fish so that there is more space and they can still be in the same water as there moms. I bought a fish net breeder and my baby fish have survived really well.Plastic pollution in the world’s oceans is a problem that has recently gained a lot of attention. Earlier this year a report from the claimed there and president Obama into law late last year. Now, a new study shows that the problem may be more urgent than first thought—some baby fish choose over natural food, leading to stunted growth and changes in behavior.
