  Description:
    Abstract: SUMMARY: Represented here are results of studies on the diet, size/age frequency, age, sex and reproductive status of Pacific halibut. These studies were begun as part of an effort to quantify the ecosystem level effects of the commercial harvest of halibut as part of a 10 year study to evaluate the commercial harvest of halibut in Glacier Bay National Park. The studies represented here were initiated to understand the ecological consequences of halibut diet and to elucidate patterns of morphological, size/age frequency, and reproductive parameters which could provide needed data to model the effects of commercial fishing on halibut. ABSTRACT: This dataset contains information on Pacific halibut (Hippoglossus stenolepis) processed for stomach contents, morphological characteristics, age and reproductive condition which were captured in Glacier Bay National Park. The primary emphasis was on the sport catch due to the wider range of size frequency classes but some data from the commercial harvest is included. PURPOSE: These data were collected as part of an effort to quantify the ecosystem level effects of the commercial harvest of halibut as part of a 10 year study to evaluate the commercial harvest of halibut in Glacier Bay National Park. Knowledge of the diet, age/size frequency classes, reproductive condition, and sex were lacking for halibut and was determined to be necessary to evaluate what effects the commercial harvest has on Glacier Bay.

  Access_Constraints: Some Glacier Bay Ecosystem Project data sets may contain data with access constraints. Such areas include sensitive information on the locations of endangered species or cultural artifacts and data which contain private or confidential information. Data sets which are not complete may have access constraints until completion. Please contact the Infromation Management Systems Administrator at the Glacier Bay Field Station for details on any access constraints.
  Use_Constraints: Some Glacier Bay Ecosystem Project data sets may contain data with use constraints. Such areas include sensitive information on the locations of endangered species or cultural artifacts and data which contain private or confidential information. In addition some data sets are collabrative efforts with outside researchers and represent unpublished work for which we request respect for intellectual rights. Some data sets are not complete and if access is given the use may be restricted until completion. Please contact the Infromation Management Systems Administrator at the Glacier Bay Field Station for details on any access constraints.
