I fish to eat. My tenkara kit (include the rod, a fixed line, and a few flies) weighs about 3 ounces (85 g). That’s less than a single protein-rich dinner, but the payoff from even one decent-sized trout (photo above) is far greater.
When I think about weight in my pack, food is the variable I have a bit of control over. Carbs and fats are pretty efficient in terms of both calorie-to-weight and calorie-to-volume ratios: cous cous, rice, tortillas, chocolate, chips, nuts, oil, etc.
But protein is where the math kind of falls apart. Jerky, protein powders, freeze-dried meat – it adds a bit of bulk and weight if I want to carry enough to meet reasonable protein intake targets. That’s where the tenkara kit comes in. A 3-ounce (85 g) investment opens up the possibility of catching meals that supply more protein than what is required from the added food weight I don’t really want to carry.
A 16-inch trout is a good benchmark. Whole, it averages about 1.5 pounds (0.7 kg). After cleaning and cooking, yield is ~45%, or roughly 11 ounces (310 g) of edible flesh. That translates into:
-
- Protein: ~70–80 g
- Calories: ~350–400 kcal
- Fat: ~10–15 g (with omega-3s)
- Vitamin B12: ~14 µg (~580% DV)
- Selenium: ~97 µg (~175% DV)
- Phosphorus: ~880 mg (~125% DV)
- Potassium: ~1,260 mg (~27% DV)
- Vitamin D: ~2,040 IU (~255% DV)
- Omega-3s (EPA + DHA + ALA): ~3.1 g (~194% DV)
That’s one fish. For most hikers, a single trout of this size (or two 12 to 13-inch trout) covers at least a half day’s protein requirement and adds about 15–20% of daily calories. It also delivers nutrients you don’t get from plant grains. nuts, or oils.
On paper, backpackers require approximately 0.6 to 0.8 g of protein per pound of body weight per day to prevent substantial muscle mass loss on long trips and maintain enough intake for routine daily repair. For someone around 200 lb, that’s 120 to 160 g/day. Most backpacking menus typically range from 70 to 90 g/day. That’s fine for a couple of days, but stretch that over a week or more, and the deficit compounds: recovery slows, lean tissue gets tapped for fuel, and appetite gets harder to control. A single trout can close that gap substantially.
The following table offers some nutritional context:
| Food Type | Pack Weight | Protein | Calories | Micronutrients |
|---|---|---|---|---|
| Trout (caught) | 0 oz | ~75 g | ~375 kcal | Rich in B12, selenium, phosphorus, potassium, vitamin D, omega-3s |
| Jerky/Dried Meat | 4–5 oz | ~70–80 g | ~350–400 kcal | High sodium, limited micronutrient range |
| Protein Powder (80%) | ~3 oz | ~70–80 g | ~330 kcal | Minimal micronutrients, poor satiety |
| Freeze-Dried Meal | 5–6 oz | ~30–40 g | ~500–600 kcal | Varies, usually carb-heavy |
The efficiency (measured as grams of protein per carried gram of food weight) seems obvious. One fish is equivalent to 4 to 5 oz of jerky or a few scoops of protein powder, but with no carried food weight. Two fish in a week offset the tenkara kit weight entirely. If I catch and eat more than that (which I do at least 90% of the time), I’m ahead on both weight and nutrition.
Obviously, this isn’t about banking on fish for survival. It’s about building some flexibility into my food plan:
- No Fish: I carry enough protein to get ~90–100 g/day. That’s my minimum protein requirement for long trips.
- Occasional Fish (every 2–3 days): My protein intake rises to ~120 to 140 g/day.
- Frequent Fish (daily): Protein hits target or above. Food weight reduced by 2 pounds or more. Micronutrient intake is significantly improved.
Each outcome works out OK, and the system doesn’t collapse if I catch nothing. But the payoff for catching and eating fish seems pretty high.
On a 10-day trip, a baseline ration with enough protein weighs around 15 pounds. By planning to carry 70% of protein needs in food (~90–100 g/day), I can trim at least 1.5 pounds off that weight. If I catch even five trout over 10 days (i.e., one every other day) I cover the gap completely and add ~2,000 kcal in the process. The 3-ounce tenkara kit pays for itself as soon as I catch two fish. Beyond that, every fish reduces the effective pack weight and improves the nutritional balance of the trip.
The benefits:
- Muscle repair: Amino acids rebuild fibers stressed by long miles and heavy packs.
- Catabolism prevention: Adequate protein slows lean tissue loss when calories run short.
- Inflammation control: Omega-3 fats in trout may help reduce exercise-induced inflammation.
- Satiety: Protein keeps hunger and insulin levels in check better than carbs and fats alone.
One way to look at the physiological balance here: get your energy from carbs and fats, but preserve your function and resilience with protein.
When I look at the rod as gear: a tenkara kit is ~3 ounces (the same weight as a few scoops of protein powder). The difference is that the rod can produce ~75 g of protein with every meal, plus nutrients that I cannot obtain from anything else in my pack. Viewed this way, tenkara is one of the lightest and most efficient “nutrition systems” I carry.
For me, fishing with tenkara isn’t about survival (although I do think about what could happen if I lost all of my food to a bear). And it’s not just about recreation (although I have to admit, it’s a pretty fun activity to enjoy in the backcountry). Instead, it’s a deliberate part of my ration planning process. It trims carried protein weight, fills in critical nutrients, and balances a carb-heavy trail diet. One fish is enough to hit the daily protein target. Two fish offset the rod’s weight entirely. More than that, and I’m not just carrying less – I’m eating better!

Appendix: Backcountry Tenkara Gear
My minimalist kit – this goes with me everywhere (day hikes, business travel, backpacking trips when I really want to save weight and fishing is incidental but essential for food supplementation):
- Rod – Tenkara USA Ukiyo – about 2 ounces
- Pouch – Hartford Gear Trail Pouch – 0.3 ounces
- Tackle – license, 5m of 5x tippet, 12 ft #4.5 level line, foam line spool, one dozen flies in a tiny zip bag – 0.5 ounces
- Flies – my basic selection focuses on versatility and includes #12 to #16 kebari-style and western-style soft-hackled flies with silk thread bodies in various dark and light shades (dark brown, medium olive, cream, and orange).
On trips where fishing is the primary focus, I will swap out the Ukiyo with a Tenkara USA Hane (for small streams) or Tenryu TF39TA (for alpine lakes). If I need more flexibility in the type of flies I’m fishing (e.g., I’m casting delicate tiny midges to wary trout and prospecting with a weighted woolly bugger), I may bring up to 3 tippet spools (4x, 5x, and 6x), a tiny tube of floatant, an extra line (usually an 18-foot level line), and a few meters of 3x tippet for line-to-tippet connectors. I seldom fish with strike indicators (even nymphs) and opt for Czech-style nymph fishing techniques instead (sometimes adding a multi-colored nymphing line to the kit for large river fishing). If I know I’m going to catch-and-release trout in frequently, I may also bring a small (5-ounce) wood-framed net to minimize stress to the fish. With more tackle and more time spent fishing, I may upgrade the Hartford pouch to the Backcountry Tackle Pouch from Yonah Gear (adds about 1/2 ounce), which helps organize the additional tackle.
