Fishing cat

Fishing cat (Prionailurus viverrinus), a Vulnerable wetland wild cat of South and Southeast Asia that preys mainly on fish; population 3,200–7,500, declining over 30% from 2008 to 2023.

Fishing fleet

A fishing fleet is the set of vessels operated by a country, region, or fishery for catching fish, including supporting vessels like motherships, fish carriers, and reefers.

Fishing in India

Fishing in India, marine and inland fisheries plus aquaculture, is the world's second largest fish producer, at 197.75 lakh tonnes in 2024–25 with exports of Rs.73,890 crore.

Fishing industry: the global sector harvesting wild fish (capture fisheries) and farming aquatic animals and plants (aquaculture). FAO reports 195 million tonnes of aquatic animals in 2024, aquaculture topping 100 million tonnes, 61.8 million primary-sector workers, and 35.5 percent of marine stocks overexploited.

Fishing industry in Canada

The fishing industry in Canada, also known as fishing in Canada, comprises commercial fisheries, aquaculture, and seafood processing employing about 65,000 people, with $8.47 billion in seafood exports in 2025.

Fishing net

Fishing net: meshed gear for capturing fish by gilling, entangling, encircling, or towing. Main types are gillnets, trammel nets, seines, purse seines, and trawls; key issues are mesh-size selectivity, bycatch, discards, and ghost fishing from lost gear.

Fishing rod

Fishing rod: flexible shaft with reel and guides for casting and playing fish. Types include spinning, baitcasting, spincast, and fly rods; materials evolved from hazel and split bamboo (1845, Samuel Phillipe) to fiberglass and carbon fibre.

Fishing techniques

Fishing techniques are the gears and methods for catching aquatic life, classified as passive (gillnets, longlines, pots) or active (trawls, seines). Bottom trawling supplies about a quarter of wild marine catch but causes most seabed disturbance and discards.

Fishing vessel

Fishing vessel: a boat or ship for catching fish, whales, seals, walrus, or other sea life (IMO SOLAS definition). FAO classifies types such as trawlers, purse seiners, and longliners under ISSCFV; distinct from motherships and fish carriers.

FISiM-NGS-MDS study

FISiM-NGS-MDS (NCT04212390) is an Italian prospective observational study by the Fondazione Italiana Sindromi Mielodisplastiche enrolling about 882 adults with newly diagnosed MDS across roughly 70 centers, collecting longitudinal peripheral blood NGS data to validate dynamic IPSS-M risk assessment.

Fissidens

Fissidens, sole genus of the moss family Fissidentaceae (Dicranales), about 440 species; unique four-lamina leaves with sheathing vaginant laminae, 16-toothed split peristome, tropical distribution, three subgenera from the 2018 molecular phylogeny.

Fissidens adianthoides

Fissidens adianthoides (maidenhair pocketmoss), Fissidentaceae, is a robust bipolar wet-habitat moss with unistratose laminae and a pale marginal band, confused with F. dubius, genome sequenced 2025.

Fissidentaceae

Fissidentaceae, also called pocket moss family, is a moss family with the single genus Fissidens (450–500 species), defined by distichous leaves with pocket-like vaginant laminae; tropical diversity, Dicranales, three molecular subgenera since 2018.

Fission (biology)

Fission (biology): asexual reproduction in which one cell divides into two (binary fission) or many (multiple fission) daughter cells; typical of bacteria via FtsZ-driven septum formation, protozoa, and some invertebrates.

Fistula

Fistula: an abnormal tunnel-like connection between two body parts such as organs, skin, or blood vessels. Types include anal, arteriovenous, vesicovaginal, and tracheoesophageal; causes include injury, surgery, infection, and Crohn's disease.

Fistula of appendix

Fistula of appendix (ICD-11 DB11.4): an abnormal communication between the vermiform appendix and a hollow viscus, vessels, or skin. Rare, 301 reported cases; commonest sites bladder and skin; commonest cause appendicitis.

Fistula of duodenum

Fistula of duodenum (ICD-11 DA50.2), an abnormal communication between the duodenum and skin or another organ; 3–14% of enterocutaneous fistulas, usually postoperative, with 7–40% mortality.

Fistula of large intestine

A fistula of the large intestine is an abnormal tract connecting the colon to the skin, a neighboring organ, or another bowel segment, most often caused by diverticulitis.

Fistula of small intestine

A fistula of the small intestine is an abnormal connection between the small bowel and another surface, usually the skin, arising after surgery in 85 to 95% of cases.

Fistula repair

Fistula repair, also known as vesicovaginal fistula repair, is surgery closing an abnormal opening between a woman's urinary tract or rectum and vagina to restore continence.

Fistula risk score

The fistula risk score (FRS) predicts the risk of a clinically relevant postoperative pancreatic fistula after pancreatoduodenectomy, scoring pancreatic texture, pathology, duct diameter, and blood loss.

Fistulae involving female genital tract

Fistulae involving female genital tract (ICD-11 GC04.1) are abnormal passages between the genital tract and bladder, urethra, rectum, or skin. Mostly obstetric injuries from obstructed labour; 50,000-100,000 new cases yearly; surgical closure 80-95%.

Fistulectomy

Fistulectomy is a surgical operation for anal fistula in which the entire fistula tract is excised over a probe, rather than laid open as in fistulotomy.

Fistulotomy

Fistulotomy is a surgical procedure that cuts open a fistula tract along its full length so the wound drains and heals; it is the standard operation for simple anal fistulas.

FIT-ATOMIC trial

The FIT-ATOMIC trial is a multi-center randomized feasibility trial testing a 20-week home-based exercise program in people aged 11 to 25 with multiple sclerosis, sponsored by Toronto's SickKids hospital.

Fitbit

Fitbit, also known as Google Fitbit, is a line of wearable fitness trackers and smartwatches founded in San Francisco in 2007 and owned by Google since 2021.

Fitness (biology)

Fitness (biology): reproductive success of an organism or genotype relative to others in its population, central to natural selection. Covers absolute vs relative fitness, LRS, inclusive fitness, and measured rates of fitness evolution.

Fitness landscape

A fitness landscape is a mapping from the genotypes or phenotypes of a biological population to their fitness, introduced in the 1930s by Ronald Fisher and Sewall Wright.

Fitoterapia

Fitoterapia is a peer-reviewed scientific journal covering medicinal plants and fungi and their bioactive natural products, published by Elsevier in Amsterdam since 1999, with continuous publication since 1947.
