It has been published as eleven tankōbon volumes by September 20, 2023. In July 2020, it was announced that the manga would go on hiatus due to heavy flooding in Kosaka's home of Kyushu; the series resumed serialization shortly afterward. In November 2020, it was announced it will go on a hiatus again at a later date. Publication resumed in April 2021.

The 12-episode anime television series adaptation was announced in the fifth issue of Young Champion Retsu magazine on April 16, 2019. The series is animated by Doga Kobo and directed by Takaharu Okuma, with Fumihiko Shimo handling series composition, Katsuhiro Kumagai designing the characters, and Miki Sakurai composing the music. It aired from April 7 to September 22, 2020. The opening theme "SEA HORIZON" and end credits song "Tsuri no Sekai e" were both performed by the main cast. On April 15, 2020, it was announced that episode 4 and onward were delayed until further notice due to the effects of the COVID-19 pandemic. On June 1, 2020, it was announced that the anime series would resume on July 7, 2020, from the first episode, with the fourth episode airing on July 28, 2020.

The theme song, "Watashi-tachi no Journey" (Our Journey), is performed by Kaneyorimasaru. It aired from June 13 to August 8, 2023, on the Lemino streaming service in Japan.

Anime News Network had four editors review the first episode of the anime: Nick Creamer felt the premiere suffered from "structural, narrative, and aesthetic issues" that prevent it from capturing the same rural Japan aura as Laid-Back Camp and displayed "tonal incongruity" with its subject matter and the Breakwater Club's hostile treatment towards Hina; Rebecca Silverman was also critical of the fishing club's cruel tactics on Hina but was commendable for their faithful portrayal of "the attitude of small coastal towns" and their various activities, concluding that fans of "slow-paced fishing stories" will enjoy it but may not attract others beyond its targeted genre audience; Theron Martin wrote that: "[T]echnical merits here are decent but nothing exceptional, so the question here is going to be whether the "cute girls" appeal can draw in those not interested in the hobby. In that regard, I put it on about the same level as Tamayomi: might be watchable, but being at least receptive to the hobby in question will matter." The fourth reviewer, James Beckett, praised its "cozy slice-of-life charm" for carrying a "soft and inviting" art direction and a likable cast that will bring Hina out of her ichthyophobia as the story progresses. Beckett added that he won't watch any further, but concluded that: "It will, however, provide much edutainment for folks who either have fond fishing memories of their own, and also for anyone who is interested in learning more about the craft with the help of a bunch of nice anime girls."

Priscilla Yip of Bubbleblabber named the series "a cute high school comedy" with quality animation, writing of the vocal performances: "The accents in the voice acting help with the countryside setting of the anime." A writer for Anime Inferno thought the series offered "a remarkably nostalgic and rosy depiction of school life and serious small-town vibes." They added: "I'd also like to give a shout out to the English voice cast who used soft southern accents for the main cast in the dub. It really contributed to a quirky small town feel for the series. Actual southerners from the United States may feel different, but this Australian thought it worked well."
