Shad –What the Fly-fisherman should know

When a river is full of running Shad, it is a straightforward proposition to connect with a few. Experience tells us however that rarely do we find ourselves in just the right place at just the right time.

So what happens when there are only a few fish in the river and it is a bright sunny day? Then, the challenge of hooking up is not so simple.






My old “knowledge is power” approach may be boring but the more you know about what might be going on the better your chances become.


The official name for the American Shad, Alosa Sapidissima, does not really give us many clues to help catch them. The “Alosa” simply tells us that it is a Shad and the “Sapidissima”, which in Latin means “most delicious”, tells us that it is tasty.

Shad live in the ocean for two to three years before returning to fresh water to spawn. In the ocean they feed upon Plankton, small crustaceans and occasionally, small fish. Occasionally probably means –when they can catch them. They are not feeding when they return to the river for spawning.

They spawn in open water with no specific bottom requirements so do not have to travel very far up the river or its tributaries.

Commonly what the angler sees when the Shad are in a river is a small group of fish sweeping by and then a splashing and swirling followed by a large wake as the group reorganizes and darts away again. What you are really seeing is a group of males chasing a larger female. She will eventually release her eggs, which the males will fertilize as the eggs drift down through the water column. A female will do this two or three times during the run and are capable of laying an astonishing number of eggs.


Shad in our cool Eastern Rivers usually survive spawning and can return to spawn again. That is a pretty good argument for catch and release. A better one is a thing I read somewhere that indicated around eighty percent of the Shad in the St. John River spawn more than once.

Here is another interesting thing from the same article. It mentioned that all of the Shad from the Eastern Canadian and American rivers spend some of their time in the Bay of Fundy.

Here is the important stuff for the fly fisherman.

Shad begin their run when the water temperature in the river reaches 12c, (about 54f). Spawning begins when the temperature rises above that. The spawning run stops when the water gets warmer than 20c (68f).

In Nova Scotia the run is usually in full swing by mid-May, by mid-June there is active spawning but things are starting to quiet down, and by mid-July it is usually too warm and the run ends.

The best times to spot fish are early morning and evening. Overcast days are generally good with fish showing throughout the day. After supper is the conventional best time to head out for a bit of Shad fishing. The worst time, usually, is between 10 AM and 5PM on a sunny day.

This is true because most of the actual spawning takes place in open water at night. As darkness approaches, the fish start to become active and continue this heightened activity until full daylight the next day.



Remember though, just because the fish are not as obvious on a sunny day does not mean they are not there, not moving around the river, or any less willing to take a fly.

Your skill at reading the water can put you over some takers no matter how bright the day and even though everyone says it is a bad time for fishing Shad. Just refer them to Dobson’s Law. It says, “People who are fishing tend to catch more fish than people who are not.”




The way I figure it is that because they are not feeding, daytime Shad are likely looking for security from predators. Speaking as a predator, I look for them during the day in places they will feel secure, primarily deep sections with structure to shelter them from the current.
