Olgoi-Khorkhoi has a very low chance with high gathering

Date & Time: Thrusday 29 March 2018 15:00 to 18:00
Frequency: 85%
World name: Diabolos
Character name: Cai Luinnnis
Class/Level: Fisherman lvl 63
Party or solo: solo
In-game time: 8am to 11:59pm
Area and coordinates: South Thanalan - Sagolii Dunes
Steps:
1. Fisherman lvl 63 with ilvl 113, Gathering 551, Perception 391 and GP 656, South Thanalan - Sagolii Dunes, heat wave weather. Using Mooch II, and Patience II with powerful hook, to get HQ Storm Rider or Storm Rider for Mooch II. Bait 'Sand Leeches'.
2. First time i got 8 in game hours from 4pm to 11:59pm of heat weather, i didn't record all my catches here but i got 3 Caravan Eel and one similar missed catch (which i suppose it was the Olgoi-Khorkhoi)
3. Second time i got 16 in game hours from 8am to 11:59pm of heat weather, here is what i got in my inventory after that:
---a. Sand Bream 12 NQ and 6 HQ
---b. Caravan Eel 2NQ and 4HQ
---c. Antlion Slug 4NQ and 4HQ
---d. Dustfish 4NQ and 6HQ
---e. Desert Catfish 7NQ and 4HQ
---f. Dune Manta 1 NQ and 4 HQ
---g. Storm Rider 3 NQ
---h. Olgoi-Khorkhoi 5 fails and 1 HQ
4. A level 50 fish with a catch rate of less than15% for gathering of 550, is extremely low, this is a bug intentionally or not, but a bug.
5. I also tried to get "The Lone Ripper", but also fail once, the only time it hooked, so it seems it affects that fish too.
