Abstract In The Present Study Of Fish Fauna In The Gokand Valley Stream District Buner Khyber Pakhtunkhwa Was Explored. During Exploration Study Was Conducted In 6 Different Localities Of Gokand Stream District Buner In The Period Of January 2016 To July 2016, In Which Total 90 Specimens Of Fish Were Collected. The Total 6 Species Were Collected Which Belongs To 4 Families, 6 Orders And 6 Genera. These Species Were Pantius Spohore, Barilius Pakistanicus, Schizothorax Plagiostomus, Schistura Punjabiansis, Metacembelus Armatus, And Channa Gachua. During This Research Also Studied The Physicochemical Parameters Like Ph, Water Temperature, Air Temperature, River Width, And River Depth Were Also Studied. Key Words: Fish, Fauna, Physicochemical, Gokand Valley, District Buner, Kp Introduction Fishes Are Cold-Blooded Animals With Backbone (Vertebrates) Gills For Breathing Under Water, And Pair Fins For Swimming. They Live Under Water And Dependent On Water For Dissolved Oxygen, Support, Food And Shelter. The Science And Study Of Fish Is Called Ichthyology (From Greek Word For Fish Ichthyes). Fishes And Studies For Centuries, Beginning With The Early Chinese, Egyptians And Greek. The Forming Of Fish And Other Aquatic Animals Is Called Aquaculture [1]. Fishes Is The Only Major Group Of Vertebrate Which Very Much Effect On Human Civilization From Ancient Time To Date. “The Most Wonderful Mystery Of The Life May Well Be The Means By Which It Created So Much Diversity From So Little Physical Matter” Inland Waters And Freshwater Biodiversity Constitute A Valuable Natural Resource, In Economic, Cultural, Aesthetic, Scientific And Educational Terms. Freshwater Fishes Are Among The Most Diverse Groups Of Vertebrates In The World, Exhibiting Extraordinary Taxonomic Breadth, Endemism, And Geographic Scope In Their Distribution [2]. 18467 http://annalsofrscb.ro Annals of R.S.C.B., ISSN: 1583-6258, Vol. 25, Issue 4, 2021, Pages. 18467-18481 Received 05 March 2021; Accepted 01 April 2021 Fish Exhibit Enormous Diversity In Their Morphology, In The Habitats They Occupy, And In Their Biology. Unlike The Other Commonly Recognized Vertebrates, Fish Are A Heterogeneous Assemblage. Fish Occupied An Extra-Ordinary Array Of Habitats. They Can Be Found Thriving In Vernal Pools, Intermittent Streams, Tiny Desert Springs, The Vast Reaches Of Open Oceans, Deep Oceanic Trenches, Cold Mountain Streams, Saline Coastal Embayment’s, And So On Through Or Nearly Endless List Of Aquatic Environments [3]. The Fish Fauna Of Water Bodies Located In The Areas Under Pakistan Is Known Through A Number Of Comparatively Recent Studies Conducted At Different Places And Times [4]. These Studies Are Useful In Providing Baseline Information On Species Distribution And Diversity In Different Areas, Yet Are Deficient In Many Ways As None Of These Studies Exclusively Encompass The Species Of Special Importance And Their Conservation Status. This Study Has Been Initiated To Cover The Most Important Aspect Of Commercial As Well As Conservation Aspect Of The Fish Fauna Of Pakistan [4]. There Are Almost 28,000 Known Extant Species, Of Which Almost 27,000 Are Bony Fish, With 970 Sharks, Rays, And Chimeras And About 108 Hagfish And Lampreys. A Third Of These Species Fall With In The Nine Largest Families; From Largest To Smallest, These Families Are Cyprinidae, Gobiidae, Cichlidae, Characidae,Loricariidae, Balitoridae, Serranidae, Labridae, And Scorpaenidae. About 64 Families Are Monotypic, Containing Only One Species. The Final Total Of Extant Species May Grow To Exceed 32,500.There Is 10,000 Times More Saltwater In The Oceans Than There Is Fresh Water In The Lakes And Rivers. However, Only 58 Percent Of Extant Fish Species Are Saltwater. A Disproportionate 41 Percent Are Freshwater Fish (The Remaining One Percent Is Anadromous). This Diversity In Freshwater Species Is, Perhaps, Not Surprising, Since The Thousands Of Separate Lake Habitats Promote Speciation [5]. Fish Constitutes Half Of The Total Number Of Vertebrates In The World. They Live In Almost All Conceivable Aquatic Habitats; 21,723 Living Species Of Fish Have Been Recorded Out Of 39,900 Species Of Vertebrates Out Of These 8,411 Are Fresh Water Species And 11,650 Are Marine .At Least 180 Species Of Fish Are Reported To Exist In Pakistan Freshwaters, Including Representatives From Important Groups Such As Loaches, Carps And Catfish. There Are 28 Fish Species Listed As Inhabiting Cold Waters Of Pakistan. Most Of The Snow Trout Are Restricted To The Trans-Himalayan Region Of The Indus System. The Famous Game Fish Mahasheer And Schizothoracines Are Becoming Rare Due To Over-Fishing And The Disappearance Of Spawning Grounds, Submerged By Reservoirs Such As Tarbela And The Ghazi Barotha [6]. There Are More Than 186 Freshwater Fish Species Described From Freshwater Bodies Of Pakistan. Substantial Quantities Of Commercially Important Fish Are Caught From Rivers Annually. The Inland Commercially Significant Native Fish Fauna Comprises About 30 Species Of Which The Economically Important Species Are: Labeo Rohita, Gibelion Catla, Cirrhinus Mrigala, Cirrhinus Reba, Channa Straita, Channa Marulius, Sperata Sarwari, Wallago Attu, Rita Rita, Bagarius Bagarius, Tenualosa Ilisha, Notopterus Notopterus, Nemacheilus Spp., Tor Macrolepis, Schizothorax Spp., And Clupisoma Naziri. Many Researchers Had Valuable Contribution To The Fish Fauna Of The Khyber Pakhtunkhwa. Butt Reported 94 Species Of Fishes From The Whole Province Of Khyber Pakhtunkhwa. In District Buner Study On Fish Fauna Was Carried Out In 2013 On River Barandu District Buner By Saeed, Et Al Who Reported Total 11 Species Belonging To 3 Order And 4 Families. These Species Were Barilius Pakistanicus, Triplophysa Naziri, Tor Putitora,Crossocheilus 18468 http://annalsofrscb.ro Annals of R.S.C.B., ISSN: 1583-6258, Vol. 25, Issue 4, 2021, Pages. 18467-18481 Received 05 March 2021; Accepted 01 April 2021 Latius, Schizothorax Plagiotomus,Channa Gachua, Gara Gotyla, Glyptothorax Punjabensis,Matacembelus Armatus, Puntius Sophore And Schistura Punjabensis [6]. In Chagharzi 7 Different Fish Species Were Collected Belonging To 3 Orders And 3 Families, 7 Genera And 7 Species. These Species Were Pantius Spohore, Tor Putitora, Crossocheilus Latius, Barilius Pakistanicus, Schizothorax Plagiostomus, Matacembelus Armatus And Channa Gachua. Fisheries Play A Predominant Role Not Only In Terms Of Food Value But Also Generate Income As Well As Employment To The Public. Country’s Inland Capture Fishery Resource Comes From The Reservoirs Yet The Fish Yield Is Low .The Sustainability Of Fish Diversity And Its Abundance Is Based On The Hydrological Parameters As Well As Plankton Diversity. Stocking Of Economically Viable Native Fish Species In The Reservoirs More Productive And Is An Important Measure From Aqua-Biotic Point Of View. Ichthyo Diversity Refers To Variety Of Fish Species; Depending On Context And Scale, It Could Refer To Alleles Or Genotypes Within Fish Population To Species Of Life Forms Within A Fish Community And To Species Or Life Forms Across Aqua Regimes [6]. Aquatic Biodiversity Is Very Important Phenomenon Because It Gives Us Idea About The Life Inside The Water. That’s Way Studying The Ichthyodiversity Of An Area Is The First Effort To Understand The Aquatic Ecosystem Of The Area. Fishes Live In Almost Every Type Of Aquatic Environment, Ranging From Antarctic Water To The Hot Springs. Fishes Can Also Tolerate A Wide Range Of Salinity As Well. Ichthyodiversity Refers To Variety Of Fish Species; It Could Refer To Alleles Or Genotypes Within Fish Population To Species Of Life Forms Within A Fish Community. According To Khan And Hasan Fisheries Plays A Key Role In Boosting The Economy Of Country And Prosperity Of That Area. Identification Of Fish Fauna Is Also A Very Important Feature Of Studying A Water Body. A Valuable Contribution To The Study Of Ichthyofauna Has Been Made By The Researcher [7]. Fishes Are One Important Group Of Vertebrates Which Influences The Life Of Human In Various Ways. Fishes Have A Rich Source Of Food And Provide A Meat, Several By Products Such As Fish Meal, Fish Glue, Fish Oil, Etc. Fish Diet Provides Proteins, Fat, Vitamins A, B And D, Minerals Like Ca, Mg, P, Na, Fe, I, Etc. They Have Good Taste And Are Easily Digestible And Growth Promoting Value. Considerable Studies On Ichthyo Fauna Diversity From Fish Fauna Of The Khyber Pakhtunkhwa. Butt
