Overview of Good Aquaculture Practices

Aquaculture has seen rapid growth in the United States. In Virginia, aquaculture is expanding in the foodfish, baitfish, shellfish, and ornamental production sectors. Growth areas include pond production and indoor, intensive recirculating aquaculture systems (RAS). Continued expansion of aquaculture in the state, as well as across the region and country, demands attention to both environmental and economic sustainability.

Good aquaculture practices (GAqPs) are a series of considerations, procedures, and protocols designed to foster efficient and responsible aquaculture production and expansion and to help ensure final product quality, safety, and environmental sustainability. GAqPs include considerations for: site location; production system design; incoming seed stock; facility biosecurity; feeding management, procurement, and storage; production techniques to maximize fish health; harvest; and cleaning and sanitation basics to ensure final product quality and safety. This document provides an overview and general framework for GAqPs, oriented to Virginia’s growing pond and RAS aquaculture production sectors.

Urban Water-Quality Management Insect Pests of Water Garden Plants

Aphids (Hemiptera: Aphididae)

(numerous aquatic plants)

Aphids are often called plant lice. Several species are troublesome pests on above-water leaves (a), stems, and flower buds of aquatic plants. These sucking insects distort succulent new leaves, causing them to curl, wilt, or turn yellow. Adults are 1/8 inch long and can be winged (c) or wingless (b) with soft pear-shaped bodies with two distinctive cornicles or "tailpipes" protruding from the backs of their abdomens.
