Creating a collection development model for a marine science library

The purpose of this article is to update and build on the approximate 10,000 item collection of the Harbor Branch Oceanographic Institute Library. This article will present a history of Harbor Branch and its library, and a literature review, outlining the collection development methods of other marine science libraries and academic libraries. The article will relate brief histories of three marine science libraries. A comparative table is constructed to compare Harbor Branch Library with three marine science libraries. The methodology, or how the table was created, is explained. The comparative table will be shown and analyzed, and the results of the table discussed. Finally, some recommendations for improvement of the Harbor Branch Library will be presented.

Signboards as an aquaculture extension tool in Bangladesh

The immunological response to handling stress of four tilapia species is evaluated. Polymorphism is examined in genes known to influence immune response in fish.

Food conversion efficiency and the von Bertalanffy growth function. Part II and conclusion: Extension of the new model to the generalized von Bertalanffy growth function

The simple model relating food conversion efficiency (K sub(1)) to body weight derived from the theoretical concepts behind von Bertalanffy's growth model, is extended here in the context of Pauly's generalization of that model. The exponent, which was fixed to 1/3 in the simple model, is in the extended model equivalent to 1-d, with d being the weight exponent of the anabolism term in Pauly's growth model. This makes the model applicable to fish for which the assumptions of the original (special) version of von Bertalanffy's growth model are violated.

Prioritizing seagrass restoration sites: study examines predictors of seagrass bed recovery

Ecologic researchers are modeling the impact of vessel grounding to seagrass beds using GIS in the Florida Keys National Marine Sanctuary. The surface creation tools in the ArcGIS 3D Analyst extension help assess both the damage and recovery of these seagrass beds.

Role of fisheries extension officers in FFDA at Balasore

The first FFDA in Orissa state was established in the year 1976. The study was conducted in Balasore district of the State. The findings revealed that all of the FEOs were not well qualified but trained and experienced. The duration of training obtained varied from 3 to 10 months. An FEO has a large area under his jurisdiction. Cycle was used by most of the FEOs to visit the fish farmers which resulted in infrequent visits. The FEOs were not satisfied with the working conditions, promotion avenues and conveyance facilities. There was interference of political bodies in leasing out ponds. The amount of loan sanctioned was not adequate to start fish farming. They also revealed that marketing aspects were totally neglected by the FFDA.
