Abstract
With the stress placed on our natural resources, many fisheries increasingly rely on restocking from hatchery-reared sources in an attempt to maintain commercially viable populations. However, the mortality rates of hatchery-reared fishes during the period directly following release are very high. The successful development of restocking programs is consequently dependent upon production and release strategies that lead to improved migratory, antipredator and feeding behaviour in hatchery fish. While relevant individual experience prior to release might improve performance, social learning potentially provides a process whereby fish can acquire locally adaptive behaviour rapidly and efficiently. It is now well over a decade since Suboski & Templeton (1989) raised the possibility of using social learning processes to improve the post-release survival of hatchery-reared fishes. This period has witnessed considerable progress in the understanding of how social learning operates in fish populations. We review new methods and recent findings that suggest how social learning protocols could realistically be applied on a large scale to enhance the viability of hatchery fish prior to their release into the wild. We also suggest a practical pre-release training protocol that may be applied at the hatchery level.

The hypothesis that shoaling fish can obtain information about a predator's approach from changes in the behaviour of other shoal members was tested in an experiment in which receiver minnows (Phoxinus phoxinus) behind a one-way-mirror could observe the reaction of transmitter minnows threatened by the stalk of a pike (Esox lucius) model. Although the receiver minnows were out of visual contact with the pike model they decreased their foraging behaviour and started hiding when the pike model cam...

The decision rules governing forage area copying behaviour were investigated in shoaling fish. Shoaling goldfish were offered two equal food patches, one of which was adjacent to an equal-sized shoal feeding behind a transparent barrier. When food was low, goldfish foraged according to an area copying rule, but under high and zero food area copying disappeared. Only under high food density did equal numbers of fish feed at both sites as predicted by foraging theory. Under zero food the fish were...

Pike-naive fathead minnows (Pimephales promelas) were fed ad libitum or deprived of food for 12, 24, or 48 h and then exposed to either conspecific alarm pheromone or distilled water and the odour of a predatory northern pike (Esox lucius). Minnows fed ad libitum or deprived for 12 h showed a stereotypic alarm response to the alarm pheromone (increased time under cover objects and increased occurrence of dashing and freezing behaviour); those deprived of food for 24 h showed a significantly redu...

Naive European minnows (Phoxinus phoxinus) do not show a fright reaction when they first encounter the odour of a natural predator (the pike: Esox lucius) or the odour of a non-piscivorous exotic (tilapia: Tilapia mariae). A conditioned fright response to both these odours will however develop if minnows experience them in a potentially dangerous situation, for example, in conjunction with Schreckstoff, the ostariophysian alarm pheromone. Although minnows respond to both odours the reaction to t...

Fathead minnows (Pimephales promelas) have an alarm substance (AS), or 'Schreckstoff', in epidermal club cells. Mechanical damage to the skin, as caused by a predator attack, releases the AS. The area in which conspecifics detect AS may be considered dangerous or risky because of the high probability of a subsequent predator attack. We exposed fathead minnows to water from one of two habitats (an open-water site and a vegetated-cover site) that we mixed with either AS or a distilled water contro...

Efficient feeding is crucial for the growth, survival and reproductive success of most animals. In artificial-rearing environments, however, animals are deprived of many stimuli normally experienced in the wild, which may alter feeding behaviour, and thus influence their survival and reproductive success upon release in nature. In a laboratory experiment, we investigated the effect of hatchery rearing on the ability of brown trout, Salmo trutta, to capture and consume a novel live prey item. Hat...

In this study we tested whether brook trout (Salvelinus fontinalis) can learn to recognise predators through releaser-induced recognition learning and whether this learning enhances survival of trout during encounters with a predator. In our initial experiment, we exposed hatchery-reared predator-naive brook trout to chemical stimuli from predatory chain pickerel (Esox niger) paired with alarm signals released by damaged trout, disturbance signals, or distilled water. In subsequent tests 24 h la...

Abstract: Animal reintroductions and translocations are potentially important interventions to save species from extinction, but most are unsuccessful. Mortality due to predation is a principal cause of failure. Animals that have been isolated from predators, either throughout their lifetime or over evolutionary time, may no longer express appropriate antipredator behavior. For this reason, conservation biologists are beginning to include antipredator training in pre-release preparation procedur...

The way in which novel learned behaviour patterns spread through animal populations remains poorly understood, despite extensive field research and the recognition that such processes play an important role in the behavioural development, social interactions and evolution of many animal species. We conducted a series of controlled diffusions of foraging information in replicate experimental populations of the guppy, Poecilia reticulata. We presented novel foraging tasks over 15 trials to mixed-s...

The mortality of brown trout Salmo trutta over winter in a near-natural stream was not significantly increased by growth hormone (GH) treatment, but lipid reserves were lower in GH-treated fish. As GH-treated trout grew faster than controls, GH appears to promote growth at the expense of investment in maintenance. However, the growth promoting effect of GH was much more pronounced in the hatchery than in the stream, suggesting that the pay-off associated with increased growth investment is highe...

Abstract Predator recognition by small fishes can be acquired when chemical alarm cues released from damaged skin (by a predator attack) are paired with a novel stimulus, such as the appearance or odor of a predator. Once learned, fish can extend recognition of risk by generalizing to associate risk with additional stimuli that are similar to the conditioned novel stimulus. Here, we trained zebrafish to associate a novel auditory stimulus with predation risk, and then tested to see if they gener...

Abstract This investigation revealed the first biological bases of embryonic development until the hatching of South Pacific bonito Sarda chiliensis chiliensis eggs. The characteristics and stages of embryonic development were described until the hatching stage. The eggs were obtained by natural spawning from wild-caught broodstocks that were conditioned to captivity for more than 1 year in a 75 m3 marine land-based aquaculture recirculating system in Chile. The water temperature range in the br...

Abstract Humans interact with fishes in many contexts including aquaculture, scientific study and companion animals. In all of these contexts, fish welfare can be compromised through anthropogenic means. Concern for fish welfare has grown considerably in recent years, with many states and territories now protecting fish through animal welfare regulations. We are not only morally obliged to ensure good welfare of animals in our care, but increasingly required to do so by law. A greater understand...

Abstract Enriched rearing has been demonstrated to shape the phenotype of hatchery-reared salmonids and improve their post-release survival in the wild, thus having an important applied value in conservation. However, it is unclear if rearing conditions or survival selection during the early life stages induce long-term fitness effects on adult phenotypes. Using a paired full-sib set-up, we investigated the influence of the environmental enrichment at the egg and fry stages on the milt quality a...
