Fish stocks indicators, which is normalized as a 0–100 proximity-to-target score, with 100 representing "at target" and 0 being furthest from the target. Stock assessments provide fisheries managers with the information that is used in the regulation of a fish stock. Biological and fisheries data are collected in a stock assessment.
In fisheries science and ecology, stock assessment is an important tool in fisheries management. In particular, to ensure continued, healthy, fish stocks, measurements of the Spawning Stock Biomass (the stock population capable of reproducing) allows sensible conservation strategies to be developed and maintained through the application of ...
Freshwater capture fisheries are dominated by the Indus River and its tributaries. The fish fauna of the Indus system in its northern part is cold-water type, while the greater middle and southern parts of the system are warm-water zones. Fisheries in rivers and reservoirs account for more than 80 percent of total inland fish production.
Fisheries science is the academic discipline of managing and understanding fisheries. [1] It is a multidisciplinary science, which draws on the disciplines of limnology, oceanography, freshwater biology, marine biology, meteorology, conservation, ecology, population dynamics, economics, statistics, decision analysis, management, and many others in an attempt to provide an integrated picture of ...
This means that decisions about stock management can also be made by the people doing the harvesting. [1] The best practice is to standardise the effort employed (e.g. number of traps or duration of searching), which controls for the reduction in catch size that often results from subsequent efforts.

At the same time, a nation's natural capital in the form of fish stocks could be greatly increased and the negative impacts of the fisheries on the marine environment reduced." [43] The most prominent failure of fisheries management in recent times has perhaps been the events that lead to the collapse of the Atlantic northwest cod fishery.
The Department of Fisheries is an attached department of Forestry, Wildlife & Fisheries Department established in 1912. The department is responsible for conservation, management and development of aquatic resources in public and private sectors. [3] The department is governed by the Punjab Fisheries Ordinance, 1961.
The institute is divided in 7 sections: [2] Aquaculture, Biology and Ecology, Nutrition, Pathology and Disease, Chemistry, Fisheries Management, and Training. The institute is head by the Director Fisheries (R&T), Punjab Lahore and each section is headed by a Deputy Director Fisheries, each of whom is assisted by Assistant Director Fisheries.
