The artisanal sector often provides tuna for the lucrative sashimi market in many locations. The quality of the catch determines whether qualifies for sashimi or sold in local markets or canned. Aquaculture: Unlike the significant aquaculture of bluefin tuna, the farming of yellowfin tuna has been done on experimental level and scattered initiatives.
⦁ Squid: It depends on the species you are talking about, you can find squid in all major bodeis of water. Some will live in warm tropical waters and other will live in a cooler climate water. Most squid live in salt water but there are some that live in freshwater as well. ⦁ Oysters: They can live in a wide range of areas due to there strenght towards temperature, salinity, and concentrations of suspended sediments and dissolved oxygen. What problems will these animals have?
This is one of the reasons why it got the name – Coat of Mail Fish. The hardy body makes it difficult for predators to be able to consume it. Also, the body has been found to help it adapt to various environments prevalent in a tank. It is important to mention that this fish is sturdy and can withstand most diseases that attack other fishes. The Port and Starboard Lightfish is easy to maintain and it can feed on anything that you give to it.
Feeding habits and role in the food chain: Daphnia feeds mainly on unicellular algae, yeast and bacteria. Upon feeding, Daphnia uses its third pair legs to filter the water allowing the proper food size in while keeping the large particles out. Beating the water with the other sets of legs create water current that brings in additional food. The feeding habit of Daphnia explains their ecological role as their lower density and consequently less food consumption could lead to algal overgrowth along with possible decline in dissolved oxygen during night.
Its body is slim and egg-shaped shaped in cross section. The corner of the mouth spread out past the eye, this is why it’s called the largemouth bass. (Bailey, et al., 2004; Boschung, et al., 2004) Young largemouth basses eats zooplankton and insects that is in the marine.
Littorina spp, or more commonly know as the periwinkle snail, is a small robust species that inhabits the intertidal zone and are commonly used in the preparation of many dishes in countries such as England and China. Littorina spp commonly ranges from sizes of 0.5-1.5 inches long with dark and even banded shells which help it to withstand strong waves. There is no definite life span of the periwinkle snail however, the amount of food and environmental factors can play a role in how long they can live for. Unlike most snails during breeding, Littorina spp often can spend more time out of the water as the embroys are contained within a brood sac and are unaffected by the external changes in the environment. Even thought periwinkle snails are a robust species a change in an
The ‘Nitrogen-fixing bacteria’ lives in soil. The root of the plant uses nitrogen from the air to make nitrates, and some of those nitrates enter the soil again. • Protection- clownfish and anemones- Anemones make the perfect home for clownfish. The anemones’ tentacles provide a protection for the clownfish to protect it from sea predators such as sharks.
Sea anemones are very relatives of orals. They provide refuge for fishes and their eggs. They are known for their symbolic relation with anemone fishes and clown fishes. Anemone fishes, in return, protect the anemone from predators and they also may also remove
These lures do not dive or sink like typical other lures , they float and the angler must give life to it by twitching, popping or jerking it across the surface (WikiHow). There is a wide range of topwater lures in the world , a commonly used design is a popper. Poppers have a concave lip and almost always have inner rattles. Other topwater lures include stick baits, walk the dog baits, spy baits, buzz baits, and frogs (WikiHow). These lures are used when fish are very aggressive or when they are feeding on forge from the surface and/or the shoreline of the water.
Brine shrimp is food to baby fish, birds, and more. However, it isn’t a threat for brine shrimp because brine shrimp can reproduce quickly. Brine shrimp shrimp are used as fish food in aquariums for the baby fish. The birds use brine shrimp as protein for their long flights. Brine shrimp feed on algae, yeast, and bacteria which are microscopic organisms.
