Spawning Biology of Channel Catfish Ictalurus punctatus (Rafinesque) in Willard Bay Reservoir, Utah [PDF]
This study was conducted on Willard Bay Reservoir, Utah, during the summers of 1972 and 1973, to study the spawning biology of the channel catfish (Ictalurus Punctatus), and to evaluate potential reproduction for this species in the reservoir. Potential reproduction was evaluated through examination of available natural habitat and use of artificial ...

Spawning biology and fertility of clown loach (Chromobotia macracanthus Bleeker 1852) in captivity [PDF]
The Clown Loach (also known as Tiger Botia), Chromobotia macracanthus Bleeker 1852, is a tropical freshwater fish, endemic in Indonesia (Sumatera and Borneo). The Clown Loach was one of the most important fish in the trade, so called ‘bread-and-butter’ species; those were very popular in the trade and exported in large number.

The reproductive biology and induced spawning of striped trumpeter, Latris lineata
Sampling of Latris lineata (n= 334) was conducted with commercial fishers on the east coast of Tasmania between May 1990 and May 1992. Relationships between fork length and weight, and age and fork length are presented for Latris lineata. Macroscopic descriptions of the stages of gonad maturation for male and female Latrislineata are verified from ...

Mosquito Biology: How a Quest for Water Spawned a Thirst for Blood [PDF]
The invasive yellow-fever mosquito Aedes aegypti preferentially feeds on human blood. A new study finds that human-biting in this important disease vector might just be an unfortunate side effect of breeding in human-stored water.

Oceanic biology: Spawning of eels near a seamount
Discoveries of the larvae of the European and American eels, Anguilla anguilla and A. rostrata, in the Sargasso Sea and of the Japanese eel, A. japonica, in the Philippine Sea indicate that these freshwater eels migrate thousands of kilometres into the open ocean to spawn.

Reproductive Biology and Spawning Patterns of Polynemus melanochir: Implications for Conservation and Population Management [PDF]
Understanding the reproductive biology of Polynemus melanochir is essential for conservation purposes and a sustainable management perspective for this species in the Mekong River system. The current study investigates patterns of ovarian histology in this species along with spawning season, fecundity, and maturity stages in female specimens caught in ...

From gametogenesis to spawning: How climate‐driven warming affects teleost reproductive biology [PDF]
AbstractAmbient temperature modulates reproductive processes, especially in poikilotherms such as teleosts. Consequently, global warming is expected to impact the reproductive function of fish, which has implications for wild population dynamics, fisheries and aquaculture.

Spawning Biology and Induced Breeding of freshwater catfish Mystus dibrugarensis : An approach to conservation [PDF]
AbstractSpawning biology of hormone induced bagridae catfish, Mystus dibrugarensis was observed in captive condition. Active involvement of male in courtship after 5-9 hr. of hormone administration was observed. Different doses of ovaprim 0.4, 0.6, 0.8, 1.0 ml/kg were used by maintaining 1:1, 2:1 and 3:1 ratio of M:F.
