FISH DIVERSITY OF MAL GAD STREAM NEAR PUROLA TOWN FROM UTTARKASHI DISTRICT, UTTARAKHAND, INDIA | UTTAR PRADESH JOURNAL OF ZOOLOGY

The present study deals with the observation of Ichthyofauna diversity of the different order hillstream from Mal Gad near Purola town, Uttarkashi district, Uttarakhand. Total of four species viz. Noemacheilus montanus, Noemacheilus rupicula, Tor chelynoides, Mastacembelus armatus were present in the 1st order stream. Ten fish species were noticed in the 2nd order Mal Gad stream (Barilius bendelisis, Noemacheilus montanus, Noemacheilus rupicula, Noemacheilus denisonii, Schizothorax richardsonii, Schizothorax plagiostomus, Barilius vagra, Barilius barna, Tor chelynoides, and Mastacembelus armatus). The presence of fish diversity was directly related to the profile of stream pattern and physicochemical parameters, temperature, and discharge of water.

AN ASSESSMENT ON THE WATER CHEMISTRY, HABITAT TYPE AND ICHTHYOSPECIES DIVERSITY OF RIVER KARNAFULI IN MIZORAM, INDIA | UTTAR PRADESH JOURNAL OF ZOOLOGY

The present investigation was intended to assess the physico-chemical parameters, habitat type and fish diversity of river Karnafuli located within a geographical location of 22°54′ 20.5″ N and 92°27′ 58.9″ E in Mizoram. The physico chemical parameters include Air and Water temperature (AT and WT), pH, dissolved oxygen (DO), free CO2, total alkalinity (TA), transparency, turbidity (TU), conductivity, phosphate, nitrate etc. and were analysed by following standard methods of American Public Health Association (APHA). The habitat types were recorded following key standard format of NBFGR and the fishes were collected by using different experimental fishing gears viz., cast nets, gill nets, drag nets, triangular scoop nets and a variety of traps and then identified by following standard literatures and keys during the study period. The values of physico-chemical parameters were found to be within the range of WHO standards portraying the better condition of the habitat for fishes. During study period, the micohabitats had been recorded as bedrocks, gravels, cobbles in the upstream rheophilic region; and, principally of fine sand in the downstream. Fish covers portrayed mainly overhanging vegetation and bottom free boulders. The riparian vegetation included mainly shrubs and trees; while, the riparian land use pattern depicted mainly human habitation, agriculture and various anthropogenic factors resulted in soil erosion and siltation. Fish diversity study revealed 45 species of fishes belonging to 35 genera, 14 families and 7 orders have been recorded from River Karnafuli during the study period. Among them, fishes belonging to the order cypriniformes (48%) were found to be the most abundant followed by beloniformes (2%) and synbranchiformes (2%), the least.

FISH DIVERSITY AND SPECIES COMPOSITION IN DIFFERENT HABITATS IN THE 1ST, 2ND AND 3RD ORDER STREAMS OF KYUNJA GAD FROM GARHWAL HIMALAYA, INDIA | UTTAR PRADESH JOURNAL OF ZOOLOGY

Present study has been conducted on spring-fed hill stream Kyunja from Rudraprayag District, Uttarakhand, India. In this work author proposed one novel approach viz., stream order wise study of distribution and diversity of fish fauna from Garhwal Himalaya, India. A Total 18 fish species (2 species in 1st order, 10 in 2nd and 16 in 3rd order stream) were recorded from Kyunja gad stream. The fish biodiversity recorded belongs to 4 families, 7 genera and 18 species. On the basis of economic importance fishes were divided into three groups, viz. major groups, minor groups and other groups. The hill spring fed stream was divided into 3 zones viz. 2 Rhithron and 1 Potamon zone for fish catch. The lower stretch (3rd order stream) was more diverse and productive and showed fish productivity of 34 CPPs (Calculated productivity points system- 16 fish species). The middle stretch (2nd order stream) showed productivity of 21 CPPs (10 fish species). The upper stretch (1st order stream) had lowest diversity and productive with fish productivity of 06 CPPs (02 fish species).

The Health Of Caribbean Coral Reefs Is Linked To Fish Diversity - The Daily Catch

The health of coral reefs can be impacted as much by the diversity of fish that graze on them as by the amount of fish that do so...

Fish Architecture: Body Shape

Picture a fish in your mind. 

Did it look like this?

or this?

what about this guy?

All of these species highlight the incredible diversity in fish body shape and form. In this post we’ll talk about the 7 most common kinds of fish body shape.

Fusiform:

Most fishes are fusiform in body shape. Characteristics of a fusiform body include being very streamlined and torpedo-shaped. Most fusiform fish often live in open water, and often have tail fins that are deeply forked to enable fast swimming. Some examples of fusiform fish include: tuna, most sharks, striped bass, mackerel (picture 1), and swordfish. 

Compressiform:

Compressiform fish are compressed laterally (from side to side), and include many species of reef fish, moon fish, and flounder. They are able to to swim very quickly in short bursts, and are often found living in and around flora, coral reefs, and other narrow places.

French Angelfish (Pomacanthus paru)

Depressiform:

These fish are compressed dorsoventrally (from top to bottom) and live mostly near the bottom of their environment. They are often predators or scavengers feeding mainly on benthic organisms. To propel themselves, they move their fins in an up and down motion; similar to a bird flapping its wings. Examples of depressiform fish include skates, rays, toadfish, goosefish, and angel sharks.

Spotted Eagle Ray (Aetobatus narinari)

Anguilliform:

From the latin word for eel, anguilliform fish, appropriately are called the eel-like fishes. They have elongated bodies, blunt or wedge shaped heads, and tapering or rounded tails. They will often have long dorsal and anal fins, and sometimes are completely lacking paired fins. Their slender shape allows them to resist current forces as they move through the water. Anguilliform fishes include eels, hagfishes, loaches, and lamprey.

American Eel (Anguilla rostrata)

Filiform:

Similar to anguilliform, filiform fishes are also elongated. However filiform fishes are also very, very thin and sometimes thread-shaped. Snipe eels (picture 2) and pipe fish are some examples of filiform fishes.

Taeniform:

Taeniform fish are ribbon shaped and laterally compressed. this shape is useful for hiding in crevasses, but doesn’t make them particularly fast swimmers. Some taeniform fish include oarfish, gunnels, and cutlassfish.

Giant Oarfish (Regalecus glesne)

Sagittform:

These fish are arrow shaped and look somewhat similar to fusiform fishes. Often, sagittform fishes are lie and wait predators, only able to swim quickly in very short bursts. These fishes include gar, pickerel, pike, and barracuda.

Great Barracuda (Sphyraena barracuda)

Globiform:

Much like their name implies, globiform fishes are very round. They are slow swimmers, and some species have modified their fins to use for walking across the bottom of their environment. Because of their slow speed, many globiform fishes employ defense strategies such as poison, sharp barbs, or sophisticated camouflage in order to prevent themselves from becoming lunch. Globiform fishes include frogfish (picture 2), lumpfish, and pufferfish.
