“…The Surma River and Tanguar Haor in the Sylhet Haor basin were chosen for the study because it was known that natural spawning grounds for carp species were once available in the various rivers of greater Sylhet, including the Surma, Kushiara, and Monu Rivers. The most distinctive river, the Halda, was also chosen because it is known as the "pure gene pool" of Bangladesh [25]. The Halda River flows through Fatikchari, Bujpur, Hathazari, Raozan, and Chandgaon Upazila (sub-district) before discharging into the Karnafuli River from the Badnatali Hill ranges of Ramgarh Upazila.…”

“…The criteria governing water quality have a direct impact on the success of fish spawning, growth, recruitment, and survival. When carp species find appropriate conditions, such as heavy rainfall, runoff from hilly water, thunderstorms, strong velocities, and high currents in river water, they begin to lay eggs [24,25]. Due to a variety of natural factors, mostly climatic and meteorological conditions, spawning habitats are expected to disappear or become extinct soon [7,26].…”

The Halda River and Haor basins are considered unique breeding habitats for carps in Bangladesh. The purpose of the study was to evaluate the natural spawning environment of carp species, with an emphasis on the hydrological conditions of the Halda River, the Surma River, and Tanguar Haor. This study, which covers the years 2021 and 2022, considered two spawning seasons. The results revealed that temperature, total dissolved solids (TDS), salinity, turbidity, conductivity, and pH were significantly different in the Halda River to the Surma River and Tanguar Haor. However, sudden rainfall and upstream runoff in 2021 were deemed as major factors causing an increment in TDS and electrical conductivity. The water pollution index was excellent in the Surma River and Tanguar Haor, and good in the Halda River. The study reported moderately reduced IMC fry production in 2021 because of inconsistent turbidity, high conductivity, and increased salinity which interrupted the ideal spawning habitat. However, in 2022, the spawning environment was favorable in the Halda River, while the Surma River and Tanguar Haor were considered to be comparatively favorable in both years. Differences were also found in the climatic and meteorological conditions, which revealed uneven rainfall, higher temperatures, decreasing water discharge, and low water levels. The meteorological data also revealed that the overall rainfall showed a decreasing trend for all sites in the last 20 years causing an interrupted water discharge. It was discovered that the amount of carp spawn obtained in the Halda River was greater than that obtained in the Surma River and Tanguar Haor. In terms of hydrological conditions and spawning performance, the Surma River and Tanguar Haor were reported to have significant differences, which may be due to their geographical location.

“…Small changes in such variables have an impact on fish growth, development, and maturity [ 27 , 28 ]. The spawning sites used by the carp species are comparable, and they have similar environmental requirements [ 29 ]. Adult carp begin their spawning migration in early March due to rains, rising water temperatures, and increasing water flow from the Himalayas.…”

This study aims to provide a thorough ecological understanding of fin fish diversity within carp spawning grounds in the Surma River and Tanguar haor. Over two spawning seasons, this research investigates ecological factors impacting fin fish diversity and abundance in carp spawning grounds of the Surma River and Tanguar haor, emphasizing water quality, habitat features, spawn availability, and environmental influences. Fish spawn samples were collected with eight “Savar nets” at chosen sites and reared in a fiberglass tank at the mini hatchery for species identification. The representative spawn samples were examined under a microscope for preliminary species identification before rearing. The study found that both the Surma River and Tanguar haor offer ideal conditions for carp spawning due to factors such as water quality, natural food availability, habitat suitability, and favorable climatic conditions. The study identified 39 fish species under the 10 fish groups from both locations, with a higher percentage of carp species (31.42%) in the Surma River in 2021 compared to 2022 (22.50%). In Tanguar haor, the percentage of carp species was 7.55% and 6.50% in 2021 and 2022, respectively. The Surma River’s ecological indices (2021-2022) indicated decreased diversity, likely due to environmental degradation, while Tanguar haor showed lower diversity possibly attributable to multiple environmental stressors. The dominant carp species, Labeo calbasu, Labeo bata, and Labeo gonius, were identified in both the Surma River and Tanguar haor. The spawning distribution varied among different locations, with some sites showing a presence of carp species, such as Hajipur T1 in the Surma River and Alam Duar T2 in Tanguar haor. The findings highlight the importance of hydrological and environmental parameters in shaping carp spawning habitat distribution and abundance, contributing to aquatic biodiversity conservation and resource management.
