Can you eat fish on Lent?

Lent is the 40-day period leading up to Easter in the Christian calendar. During this time, many Christians observe the Lenten fast, which entails giving up certain foods and activities. One of the most common questions around Lent is whether it is permissible to eat fish during this fasting period. The answers lie in understanding the purpose and historical origins of the Lenten fast.

The Purpose of Fasting During Lent

The goal of fasting during Lent is to give believers an opportunity to focus on repentance and growing closer to God. By setting aside pleasurable things, Christians can redirect their hearts and minds towards prayer, self-denial, and charitable works. The Lenten fast serves as a preparation for Easter when the death and resurrection of Jesus Christ is celebrated.

Abstaining from food and festivities reminds Christians of the sacrifices Christ made during his 40 days of fasting in the desert and his suffering on the cross. It also allows them to identify with the poor and hungry.

Origin of the Lenten Fast

The tradition of fasting for 40 days prior to Easter dates back to the early centuries of the Christian church. Documents from the 2nd century A.D. mention a 40 day Lenten fast, but specific guidelines and practices varied from place to place over the first few hundred years after Christ.

Eventually, the Lenten fast developed into abstaining from all meat, eggs, dairy, and animal products for the duration of Lent. Only one full meal per day was permitted, if any food was consumed at all on fasting days. This rigorous fasting reflects practices that were common in ancient Christian traditions of asceticism and monasticism.

Are There Exceptions?

As Lenten fasting has developed over the past two millennia, certain exceptions and concessions have arisen. The dietary restrictions are not applied to all groups within Christianity. The elderly, sick, pregnant, or very young are frequently exempt. However, even for those who strictly keep the fast, churches sometimes grant exceptions for particular feast days that fall within the Lenten season.

Fish is one of the most common concessions granted during Lent. So why is fish considered acceptable on fast days compared to other kinds of meat?

Why Fish is Permitted

There are a few reasons why fish may be eaten during Lent when other meats are avoided:

  • In ancient times fish was considered a different category of food compared to land animals. Marine creatures were often thought of as still belonging to the “water world” rather than being ordinary meat.
  • Jesus ate fish and multiplied loaves and fishes to feed the five thousand. Fish figured prominently in several Gospel accounts of his ministry.
  • Fish were an important part of the diet in many coastal regions where Christianity took root, like the Mediterranean and Northern Europe. Banning fish would have made fasting especially difficult.
  • In some areas fresh fish was one of the only options for protein so it was permitted out of practicality and compassion.

For these reasons, many churches classified fish alongside vegetables as an acceptable food to eat during Lent and other fasts. While the exact rules differ between Christian denominations today, this concept of fish being in a different category persists in many Lenten traditions.

Other Animal Products

While fish is usually allowed, other animal products like meat, milk, eggs, and fats from warm-blooded animals are restricted during Lent. So foods like chicken, beef, pork, milk, cheese, cream, and butter are avoided. However, foods with oil from cold-water fish or olives, like cod liver oil and extra virgin olive oil, are sometimes permitted.

Regional Differences

Lenten fasting practices vary regionally, even within the same Christian denomination. Some traditions abstain from fish and all animal products for at least a portion of Lent. For example, Eastern Orthodox churches restrict fish as well as other animal products during Great Lent before Easter. But fish is still consumed during feast days and on weekends.

Roman Catholic guidelines typically allow fish on Fridays and Ash Wednesday. But some slight variations exist between national churches. In the United States, Catholics also permit beaver, muskrat, turtle, and frogs since these have historically been classified as fish.

Protestant churches do not have any universal rules about fish or other dietary restrictions during Lent. Practices range from avoiding all meat to simply setting aside one food or activity to focus on spiritual reflection.

Seafood Restrictions

So Lenten traditions give fish special status as an accepted food when animal flesh is otherwise forbidden. However, seafood is not permitted without restriction. Firstly, cold-blooded sea creatures like shrimp, lobster, crab, octopus, squid, alligator, turtles, and frogs are sometimes classified as meat, not fish.

Secondly, different regulations apply on Fridays and fast days compared to Sundays and feast days in many traditions. For example, seafood dishes like calamari may be enjoyed on a Sunday in Lent when a full meal is allowed, but restricted when only one small meal is permitted on Wednesday.

Holy Week

In the week leading up to Easter, known as Holy Week, fasting is often more intense with fish and other concessions being withdrawn. Some Catholic communities avoid fish on Good Friday. Others restrict fish and animal products completely during the final days of Lent leading to Easter Sunday.

Orthodox churches also intensify fasting during Holy Week, even prohibiting wine and oil on certain days. So while fish is consumed during the Lenten season leading up to Holy Week, the requirements become more stringent in the final stretch before Easter.


In summary, whether or not fish is permitted during Lent depends on the particular Christian tradition and the liturgical calendar. Special allowances are frequently made for fish and seafood that do not apply to other animal products. However, even fish consumption is often limited or eliminated as the season progresses towards Easter.

The Lenten fast centers around repentance, self-restraint, charity, and focusing on Jesus Christ’s sacrifice as Easter approaches. While practices vary, the symbolic role of fish in the Bible and history of the early church give it a unique place in many Christians’ Lenten experience.
