Maturation Biology Of A Rare Hill-Stream Fish Botia dayi Hora From Garhwal Himalaya, Uttaranchal

Environment Conservation Journal, 2006
The paper deals with maturation biology and spawning behaviour of a hillstream fish Botia dayi (Hora) collected from river Khoh in the foothills of Garhwal Himalaya, Uttaranchal. Seven maturity stages were determined for the fish. Based on GSI, Dobriyal

Routing Optimization of Cable‐Driven Octopus‐Inspired Manipulators With Minimal Actuation via Genetic Algorithm and Finite Element Method

Advanced Intelligent Systems, EarlyView.
Soft robotic arms are promising for gentle grasping but often rely on bulky actuation systems. This work presents a computational design framework that optimizes tendon number and routing to achieve target grasps with fewer actuators. Validated on an octopus‐inspired underwater arm, the approach enables efficient, underactuated soft manipulators for ...

MusicSwarm: Biologically Inspired Intelligence for Music Composition

Advanced Intelligent Systems, EarlyView.
Biologically inspired swarms of frozen foundation models self‐organize to compose complex music without fine‐tuning. By coordinating through stigmergic signals, decentralized agents dynamically evolve specialized roles and adapt to solve complex tasks.

The reproductive study of Golden Snapper (Lutjanus johnii) in Hormozgan waters

‬‭Majallah-i ̒Ilmī-i Shīlāt-i Īrān, 2000
Golden snapper is a species of family LUTJANIDAE which is distributed in Hormozgan waters. Biological (especially reproductive) study of each species is necessary both for the cultivation and stock assessment of that species.

A review of the historic and present ecological role of aquatic and shoreline wood, from forest to deep sea

Biological Reviews, EarlyView.
ABSTRACT The ecology of forests, their losses, and terrestrial wood decomposition dynamics have been intensively studied and reviewed. In the aquatic realm, reviews have concentrated on large wood (LW) in rivers and the transition from freshwater to marine environments in the Pacific Northwest of North America. However, a comprehensive global synthesis

Shaping research in marine functional connectivity for integrated and effective marine science and management

Biological Reviews, EarlyView.
ABSTRACT Effective knowledge of ecological connectivity at sea and at the land–sea interface is key to supporting global policy goals to conserve and restore ocean biodiversity and function. However, a persistent lack of commonality in terminology and understanding around the concept of connectivity in marine ecological studies hampers its integration ...

A guide to the interpretation of sea trout scales [PDF]

, 1996
The overall purpose of this guide is to provide a manual for the collection and interpretation of sea trout scales. A brief introduction considers the advantages and disadvantages of using scales to determine age and growth. To ensure that scales are

Concepts of spawning targets [PDF]

, 2000
This report discusses the concepts of spawning targets. Spawning target setting is based on the fact that the number of smolts produced by any given river is constrained by habitat availability.
