The youngest fish is called as shinko シンコ (under 5 cm). Than Kohada コハダ (around 10 cm) is slightly more mature. After the fish mature enough, Japanese people call them as Nakazumi なかずみ and finally konoshiro コノシロ (after 15cm) after Kohada fish is getting very mature.

Kohada Konosirus punctatus is different than American gizzard shad Dorosoma cepedianum.

Kohada is one of the "must have" in classic edomae sushi. It is considered as the king of the silver-skinned fish. Kohada is rarely to be used for non-sushi (sashimi or fancy dishes).

Flavor & Texture
The kohada, in general, has a oily, bold, robust flavor. The meat should be moderate soft, melts and strong fishy smell. Very shinny skin is soft and highly agressive flavor too. The meat has white to pink color.

The youngest (shinko) has softer texture and less fishy smell. The oldest (konoshiro) has meaty texture and has more fishy smell. The problem with the oldest kohada is the bone. When the fish is getting older, the bone is getting more and stick to the meat. The harder for the chef to process.

Fact
Small fish. The youngest one should be 3cm to 5cm and the oldest one is 15 cm. It is expensive fish. The shinko (youngest) can reach $ 300/lb.

Harvesting
They can be caught by net. They are available along the shore. Usually they are accidentally trapped by nets. It is consider as rare fish and live in schools. The greatest Kohada live around shoes of Central Japan, eastern China and Korean Peninsula. the best season to harvest Kohada fish is early fall.

Sushi Preparation
Preparation needs more attention because it is small fish. After the chef take out the bone, the meat should be marinated with either salt, vinegar, lemon or lime. Some chefs are using salt for an hour, than wash out with vinegar and lemon. It is the time for chef to show how great their skill to battle the fish smell and increasing texture and flavor at the same time. The older the fish, the more bone they have, the harder the process.

Shallow cutting is the process to cut the skin little bit when the sushi is presented. The function of the cutting techniques is giving air to touch the meat for texture and flavor.

Konoshiro is very rarely for sushi because it is hard to take off the bone. Konoshiro (oldest) has too strong smell for sushi. Some chef has slightly seared the meat or grill them before they make a sushi.
